Signs Your Electric Panel Needs an Upgrade – Safety & Costs to Replace

electric panel

Electrical panels serve two purposes – to provide electricity and safety.

However, it may be difficult for many homeowners to assess the state of their electrical panels and whether or not the panel does its job properly.

Even tougher is the decision when an electrical panel should be considered dangerous and unsafe and if it has to be replaced.

Ultimately, safety for your family and your home comes first. You may be wondering if the electrical panel in your house needs to be replaced or upgraded?

Electrical panels have a typical lifespan is about 40-60 years. However, age is not always a primary concern. Some older electrical panels are inherently faulty and need to be replaced with newer electrical panels with safety upgrades. Electrical panels that are undersized or do not meet National Electric Code safety protection standards should be updated or replaced regardless of age.

Now, I realize that’s oftentimes easier said than done. Electrical updates are not cheap. An electrical panel change – or upgrade – can look like a big challenge to undertake.

This is why we need to know how to recognize the signs of a failing electrical panel first, understand the consequences second, and lastly, what steps we need to take.

Signs That You May Need to Replace Your Electrical Panel

Electrical panels do not last forever and need to be replaced as needed. There is no definitive timetable on when to replace an electrical panel. However, if you see any or all of these items below, you should consider replacing your electrical panel.

Some things will be a clear-cut indication that there may be something wrong with your electrical panel or wiring. In these cases, it is recommended to have a certified electrician carry out a detailed inspection.

1. Rusted Electrical Components

Having rust in the panel is never a good sign. This is a clear indication that moisture has gotten inside the electrical panel, and we all know electricity and water can be a fatal combination.

The fact that there is rust means that the electrical panel is, or has been, subjected to water. There may be different causes for the rust to appear, like chipped paint, higher humidity levels, or water leaks.

High amounts of electrical current are passing through the panel. And the presence of water in any shape or form is not something we want.

This will eventually render the panel unable to work properly, and this is really dangerous as it can lead to electrical faults and fires.

A rusted electrical panel needs to be replaced. The reason that caused the rust needs to be corrected to prevent rust from happening in the future.

2. Circuit Breakers That Trip Constantly

If your breakers trip regularly, this may signify a potential electrical problem with your electrical panel or wiring. It could also just mean you have a bad breaker.

The reasons why a breaker may constantly trip are:

  • The electrical circuit is overloaded.
  • There is an electrical fault.

If this is happening, make sure you speak with a certified electrician to have the panel and the wiring inspected and assessed. In some cases, a panel replacement may be needed.

Questions to ask your electrician before replacing the entire breaker panel:

  1. Is it the same breaker that routinely trips? If the same breaker routinely trips, it’s likely a problem with the breaker itself or the circuit coming into the breaker.
  2. Are there burn marks present on the bus bar where the breaker connects inside the panel? This indicates that there’s a problem with the circuit breaker, the panel, or both. Either way, the panel’s replacement is recommended if there are burn marks on the bus bar.
  3. Are the breaker double-tapped, meaning there multiple circuits connected to a single breaker? When two or more branch circuits enter into a single breaker designed to carry multiple circuits, the breaker will routinely trip. Repair may be as simple as separating the circuits into separate breakers or installing a tandem breaker if the electrical panel allows for it.
  4. Is the breaker undersized for the circuit? An undersized breaker will routinely trip under certain usage loads. Running too many items at one time can also overload and trip a breaker.

3. Underpowered Electrical Panels

Electrical panels have a power rating. Usually, this directly correlates with the size of the electrical panel and how many breakers it can accommodate inside.

Some of the first electrical panels that were installed in residential houses had about 60 amps of power. Later this increased to 100 amps.

Today this considered being insufficient. For example, most homes today have 200 amps of power.

If you live in a home with an older electrical panel, it may be underpowered, and when you plug in a few more electrical appliances, the breakers will trip.

In a few cases, it is recommended to change the electrical panel.

  • If you are going to be doing some remodeling.
  • If you are going to be adding new electrical appliances that have high electrical consumption
  • If more people are going to be living in your home or building.

4. Burned Areas in the Panel

We touched on this earlier but let’s go into more detail. Even though a good electrical panel is believed to last between 30 and 40 years, everything eventually breaks down.

Despite what the manufacturer says, mechanicals oftentimes breakdown prematurely. Manufacturer specifications are really only an estimate given based on ideal circumstances.

Not only the electrical panel itself but the wiring wears down with time, too.

Damaged insulation on the wiring can produce electrical arcs that generate high amounts of heat that can easily start an electrical fire.

Look for burned and charred areas or any distinct smells:

  • In the electrical panel at the breaker or on the bus bar if the breaker is removed.
  • Around the breakers. Are the connectors scorched?
  • Around the wires. Is the insulation around the wires melted?

If you notice anything that may raise a concern, have the panel inspected by a licensed electrician.

5. Breakers Not Working Properly

The electrical breakers are the main component that is providing both your home and family with safety from electrical fires and electrical shocks. So if the breakers are not working properly, this puts you at risk.

This is why breakers should be frequently inspected and tested if they work properly.

6. Bad and Old Wiring

Old wiring can pose a lot of safety issues due to natural wear and tear.

Bad wiring practices can also be hazardous and may require your electrical panel to be changed or upgraded.

Some examples are:

  • Oversized breakers – During the home inspections I have done, I have stumbled upon some mismatched wiring and electrical breakers. This is more than a code violation; it is also incredibly unsafe and dangerous.
  • Double tapped electrical breakers – They can be another fire hazard waiting to happen. And a good reason as to why a specific breaker may trip more frequently than it should.
  • Messy wiring – This often refers to multiple wiring connections made outside of an electrical junction box with a cover plate. We see this often in older homes where rooms were wired in series on one circuit. One leg of the wiring is replaced and then ties into several additional branch legs of older wiring outside of a junction box.

7. Consolidating Multiple Subpanels

Every home has one main electrical panel, which is the main source of electricity.

Some homes may also have one or more subpanels installed. There can be several reasons why your home may have subpanels:

  • In some cases, it may be more convenient to operate specific electrical circuits from a subpanel. For example, this can be seen in garages, granny flats, and other home extensions.
  • A subpanel may be more cost-efficient in some cases. Instead of running multiple wiring with a subpanel, you can have single wiring running to the main panel.
  • We see this often in older homes where the main panel box is at maximum capacity. Adding additional circuits is to either upgrade the main panel or add a subpanel.

If you are going to consolidate multiple subpanels, you may need to replace or upgrade your main electrical panel. This can often be done with one 200 amp panel. Some larger homes may require two 200 amp panels, where one is the main and the second is an equal-sized subpanel.

However, one of the big disadvantages is that consolidating multiple subpanels will be followed by a lot of wiring work, incredibly laborious and expensive.

8. Dimming or Flickering Lights

Another good sign that the time for an upgrade of your electrical panel may have come is observing constant flicker or dimming of the lights.

Usually, the reason may be an underpowered electrical panel, especially if you live in an older home with an older panel. Sometimes the reason for that can also be faulty or bad wiring. In either case, an electrician inspection is needed to determine the reasoning.

9. You Use a Lot of Power Strips

This is one of the little things that may go unnoticed by many homeowners. Throughout the years, I have consulted a lot of clients. And in some cases, I have been pointing out that using a lot of power strips is not necessarily the right solution.

The electrical outlets in our home are connected to different electrical circuits.

These electrical circuits are usually either 15 or 20 amps for a standard 120-volt circuit. In a certain way, we are limited by the amperage of the specific circuits.

If you add one of these long power strips to an outlet and then connect multiple appliances or electronic equipment, it will trip the breaker associated with this electrical circuit.

Usually, the more demanding appliances may even need their own dedicated electrical circuit.

Trying to connect multiple appliances to the same circuit is not only dangerous, but it can damage the electrical appliances, too.

For many, this is one of those aha moments.

If you are buying a home with not enough outlets, you may have to upgrade the electrical panel to add more circuits.

Changing your electrical panel with a newer model will allow for better safety when operating higher-demanding appliances at once. It will also allow you to install more outlets and more circuit breakers in the panel.

Older Electrical Panels That Pose Safety Concerns

federal pacific

Some older electrical panels were just not manufactured up to standard from the beginning. Over time they have been proven to be dangerous and unsafe.

Even if they have been working properly for many years, there is no way of knowing if they will continue doing so. If you have one of the below electrical panel brands, it’s wise to upgrade your electrical panel.

Federal Pacific Stab-Lok Electric Panels

Federal Pacific Electric (FPE) Stab-Lok panels are a long known hazard. They are widely considered as unsafe and dangerous. They have been connected with numerous cases of electrical fires.

So, are Federal Pacific Electric Panels safe or dangerous?

Federal Pacific Electric panels have been considered dangerous by insurance companies and the Consumer Product Safety Commission. Federal Pacific Electric Panels are dangerous due to age and faulty components that have been proven to fail when tested. The breakers have been shown not to trip, causing the panels to catch fire.

FPE panels were installed in older homes built between the 1950s and 1980s.

FPE panels are a tricky subject because there is no official stance from the governmental institutions, and there have never been any recalls initiated.

However, if we look into some of the investigations and testings done on these panels, we will see that they have incredibly high rates of failing to trip in the presence of an overcurrent or short circuit.

During some tests that were carried out, the FPE panels failed to trip at extremely high rates ranging from 25% and going up to 65% in some cases.

This is making them a latent fire hazard and dangerous.

Changing the circuit breakers with newer units has not shown to be making them less dangerous, so a panel upgrade is advised.

Zinsco Electric Panels

Zinsco electrical panels are another outdated electrical panel known for failing to provide proper electrical safety.

Let’s look at whether or not Zinsco panels are safe?

Zinsco Electric Panels have been proven to fail and have the potential to catch fire. The breakers in Zinsco electric panels can melt and fuse to the bus bar causing them to fail. The breakers can also have a poor connection to the bus bar causing arcing to occur.

On the one hand, we don’t have any official position from the governmental authorities. And on the other hand, we have often seen how Zinsco panels have failed to work and even started electrical fires.

The thing that is making Zinsco panels dangerous is the way they were manufactured.

  • In the production of the Zinsco panels, there was a particular flaw. A specific aluminum alloy was used that can easily oxidize.
  • The breakers have been known to melt and fuse to the bus bar, which renders them ineffective to provide any electrical protection.
  • The circuit breakers often are loosely connected to the bus bars, which can lead to arcing.
  • The breakers may appear to be tripped, but in reality, the electricity is not cut off.

An easy way to recognize a Zinsco panel is by looking for the following labels: Zinsco, Sylvania, GTE-Sylvania, Sylvania-Zinsco.

ITE Pushmatic and Bulldog Electric Panels

Unlike the Zinsco and FPE panels, the ITE Pushmatic panels have not proven themselves unreliable. However, they are still not without their issues.

Are ITE Pushmatic electric panels safe?

While ITE Pushmatic electric panels have never been recalled, they are still considered dangerous. ITE Pushmatic electric panels are unsafe because they are outdated and likely are accompanied by aluminum or ungrounded wiring. Electricians and insurance companies recommend replacing electric panels over 40 years old, particularly where aluminum or ungrounded wiring exists.

They are easily recognizable as they don’t have switches but instead buttons you need to push when you want to switch them off.

They were produced and installed during the 1930s up to the 1960s, making them extremely old and outdated. And finding replacement parts for them can be really expensive.

With all that being said, they have been reported to fail to trip in the presence of overcurrent. The circuit breakers that are installed in these panels use a thermal tripping mechanism. While in comparison, newer units use both thermal and magnetic tripping mechanisms, making them safer and more dependable.

One of their inherent faults is that the buttons use grease, and if not frequently operated, they can get tough and stiff to operate.

Even though it may appear to be working, ITE Pushmatic electrical panel should be replaced due to its age and lower safety.

Challenger Electric Panels

The Challenger panels are another brand that is considered to pose a latent fire risk. They were one of the most popular electrical panels installed in the homes built during the 1980s and the 1990s.

So, are Challenger Electric Panels safe to have in your home?

Challenger electric panels are considered dangerous because some of the circuit breakers Challenger manufactured tended to overheat during normal working conditions. Some insurance companies will not insure a home with a Challenger panel. However, this is not true for all insurance companies.

The heat that was generated led to the breakers expanding and contracting. This causes the connection between the breaker and the bus bar to become very loose. A loose connection like this will create electrical arcs that produce tremendous amounts of heat, which will lead to the breaker melting. The result is a circuit breaker that is rendered completely useless and unable to work.

In addition to that, some of the Challenger breakers were recalled because they failed quality testing. It was discovered that they were not able to provide the necessary ground fault protection.

The Challenger panels don’t always have the Challenger label on them. Some of these panels were also labeled under the GTE-Sylvania logo.

Murray Electric Panels

Murray is another electrical panel that was installed several decades ago. There are modern Murray panels that are perfectly fine. These modern Murray panels are safe.

Are Murray electric panels safe or dangerous?

Murray electric panels were less expensive than some of the other electrical panels; however, they were considered safe and without faults. The main problem plaguing Murray electric panels is their age. If your Murray electric panel is over 40 years old, it likely needs to be updated.

During 2010 Murray circuit breakers were recalled by the U.S.Consumer Products Safety Commission (CPSC) because of the inherent danger that they possessed.

It was discovered that a spring clip could break under normal working conditions, which could lead to electrical fires and electrical shocks.

Westinghouse Electric Panels

Westinghouse is another brand of electrical panels that is very outdated and old. Westinghouse has been sold to Eaton.

Are Westinghouse house panels safe?

Westinghouse electric panels are considered safe. However, they are not without problems. The main issue that plagues Westinghouse panels is age. The breakers can also have a poor connection to the bus bar causing the breakers to overheat and melt, thus burning the connection tabs.

This was not found to be a widespread problem resulting in any recalls. If you have a Westinghouse electric panel, have it examined by a licensed electrician, especially if you see a panel with multiple brands of breakers.

If the Westinghouse panel has several other branded breakers, there has likely been an issue in the past and the bus bar could be damaged.

Due to the natural wear and tear these panels face with time, it is making them a potential safety hazard and should be replaced.

Wadsworth Electric Panels

Wadsworth is an older electric panel that is generally well known for their high quality. Wadsworth electric panels and their components are no longer manufactured.

However, are Wadsworth electric panels safe?

Wadsworth electric panels are now considered obsolete as the panels no longer meet today’s stringent safety standards. Other issues related to Wadsworth electric panels are aluminum or ungrounded wiring. The main issue plaguing Wadsworth electric panels is age.

Many Wadsworth panels are still in use today. However, they are being replaced during renovations. Typically, a Wadsworth electrical panel upgrade will include at least some electrical wiring updates.

General Switch Electric Panels

General Switch is another old electric panel that is no longer manufactured. If you have a General Switch electric panel you may have a hard thing finding replacement breakers. While many other breaker brands may fit and work perfectly fine, it’s technically not compliant.

Are General Switch electric panels safe?

General Switch electric panels are safe. General Switch panels will likely require replacement if a breaker fails. General Switch components are no longer manufactured, and replacing bad breakers with other brands is not compliant. Other related issues related to General Switch electric panels are aluminum or ungrounded wiring.

Bryant Electric Panels

Bryant electric panels, much like Murray panels, is another electrical panel that was installed several decades ago. Are Bryant electric panels still safe to have in your home?

Bryant electric panels are considered safe; however, age and condition are the main factors to whether they are safe or dangerous. Cutler-Hammer owns the name rights to Bryant and does manufacture replacement breakers under the Cutler-Hammer name. However, if your Bryant electric panel is over 40 years old, it likely needs to be updated.

Should Split Bus Electrical Panels Be Replaced?

Today’s electrical panels have one bus bar through which the electricity is supplied to the main breaker. From there, it goes to the rest of the electrical breakers.

This is useful because we can easily cut out all the power in the building by flipping the main switch in case of an emergency. However, some older electrical panels had two bus bars with no main breaker (some of the older Murray electrical panels, for example). These are known as split bus electric panels.

So, are split bus electric panels safe or dangerous?

Split bus panels are not necessarily dangerous, but they are outdated. Split bus panels do not meet current NEC codes. This means they may have higher rates of failing to provide the necessary safety.

Split bus panels haven’t been used for well over 40 years. As we stated earlier, this makes them well beyond their expected lifespan. The NEC no longer allows multiple main disconnects.

Other problems related to split bus panels is aluminum and ungrounded wiring as they were commonly part of the split bus panel install. If you find you have a split bus panel in your home, you should consult an electrician about possible panel replacement.

You can likely update the panel without a full house rewire. The NEC allows a panel upgrade and replacement of 2 prong electrical outlets without rewiring provided the circuit is GFCI protected, although rewiring with grounded wiring is the best option.

Should Old Fuse Boxes Be Changed?

Fuse boxes are another big topic that frequently comes up.

Fuse boxes were installed in older homes built before the 1960s.

Fuses are a lot different in how they look compared to the breakers.

We have a socket where the fuses are screwed in like a lightbulb. And just like the lightbulb, they have a tiny metal wiring inside that is rated for specific electrical current. If there is an overcurrent, the wire will melt and stop the electricity from flowing – this is how fuses trip.

To restore power, you need to manually install a replacement fuse or manually replace this tiny metal wiring.

And here lies one of the main dangers of fuses – they need to be appropriately rated for the circuit, and the wire inside has to be the right kind.

Installing a higher rated fuse is known as over fusing, and it is incredibly dangerous.

1. Are Fuse Boxes Dangerous?

Fuses are technically considered safe. Although outdated and regarded as old technology, they do work as intended.

If a fuse is rated for 15 amps, its tiny metal wire will burn and cut out the power if more than 15 amps are supplied. It will not be able to allow more electrical current to pass.

However, they are not designed with the modern electrical consumption needs we have today in mind.

Additionally, fuse boxes cannot provide the same safety features as the modern electrical panels, such as circuit grounding and arc fault protection.

2. Should You Replace a Fuse Box?

Fuse boxes are not installed in newer homes, so the only chance to stumble upon one of these is by buying or renting an older home.

Although not necessarily dangerous, they are considered extremely outdated. An electrician should do an in-depth examination to determine if a replacement is needed. The main issue with fuse boxes is that they may not meet the electrical needs and may not adhere to the higher safety standards we have today.

Usually, fuse boxes have to be replaced, especially if you plan to remodel or add more circuits.

How Much Does Replacing an Electrical Panel Cost?


The price for an electrical panel replacement can vary a lot depending on different factors like:

  • The actual amount of work that needs to be done.
  • What electrical panel you will be installing.
  • The type of the older electrical panel.
  • The number of electrical circuits.
  • The amperage.

The average cost for replacing an electrical panel is about $1,500-$2,000. However, it is usually not that simple. Often, older panels need additional work, which could include:

  • Relocation of the panel from a closet or cabinet to an area that meets current clearance requirements for electrical panels.
  • Wiring updates, particularly if the wiring is undersized, ungrounded, or needs to be extended to accommodate relocation.
  • Meter base upgrades to allow for the inclusion of a service disconnect or increase in amperage.

If you want to install a lower amperage panel, it can cost as little as $500 to $1,000.

For comparison, upgrading to a high-end 200 amperage electrical panel can go up to $4,000 when you add in labor costs, equipment upgrades such as wiring, meter bases, AFCI protection, GFCI protection, etc.

Do You Really Need to Replace Your Electrical Panel?

As we can see, replacing your electrical panel can be a really intimidating thing to do.

Many people will ask if it is worth spending money on a new electrical panel considering the older one is still working.

However, when we realize an electrical panel is not working properly, it may be too late.

Sometimes people may think that when their electrician recommends replacing their panel, they are doing it because they are only after the money.

As home inspectors, we have specific responsibilities to advise our clients on the house’s condition and any apparent safety issues they could be facing soon.

Our primary concern is the safety of our clients, their families, and their homes. Even though replacing an electrical panel can be costly, safety is always going to be more important.

How Long Does It Take to Replace an Electrical Panel?

Every homeowner faced with making the hard decision to replace their electrical panel may need to consider the amount of time it would take.

The time frame we will be looking at is essential because you cannot expect your home to have any electricity running during this time. Any appliances like refrigerators will be left unpowered.

The usual time for replacing or upgrading an electrical panel is generally between 6 to 8 hours. Some upgrades could take several days. If the power has to be terminated to make the upgrade, an inspection from a city building code inspector to clear a permit authorizing the power company to set the meter and turn the power on.

The time can vary greatly depending on:

  • What needs to be done.
  • The number of circuits that have to be relocated.
  • The time required to coordinate with the electrical power company properly and more.

Do I Have to Replace a Full Breaker Box?

Today our electrical needs are constantly growing.

It is not a rare occurrence to find yourself with an electrical panel that has no more space for new breakers.

Luckily it is not always 100% necessary to replace a full electrical panel.

Some electrical panels are designed to fit what is known as tandem electrical breakers. Usually, they take the same space as a standard circuit breaker but have two breaker levers that can operate two different electrical circuits.

It is important to note that a tandem breaker may not always be allowed to be installed. Not all breakers are designed to be interchangeable. Don’t try to force a breaker into a panel box it is not designed to fit into.

Tandem breakers are not used in newer buildings as they don’t offer proper AFCI and GFCI protection.

If your panel is not suitable for tandem breakers to be installed, then the only option is to replace the panel entirely or install a subpanel.

Do You Need an Electrical Permit to Change the Electrical Panel?

Nearly all changes, repairs, and upgrades on the electrical system require an electrical permit.

An electrical permit is required to make sure that properly trained specialists are working on the electrical installations and, consequently, guarantee safety, uniformity, and compliance with the electrical code.

Any major electrical work is advised to be carried out by a licensed electrician and, after that, inspected by the local building code inspector.

Appropriately trained homeowners can work on their electrical systems themselves. However, they need to apply for an electrical permit first. Even electricians do it, so this is an important step.

Still, it must be noted that doing electrical work is incredibly dangerous. Any homeowner that decides to do the electrical panel replacement or the wiring work done by themselves needs to adhere to the safety regulations. That way, they can avoid the potential dangers to their health and property.

Any damage done by electrical fires from improper electrical installations, negligence, and code violations can and probably will not be covered by the insurance companies.

Additionally, if the homeowner decides to sell their property, they must disclose any information that is known to them – including the changing of the electrical panel or wiring. Usually, they will be asked about when the panel was changed and a permit to do that.

A lack of permit may have a negative effect.

  • The buyer may ask for a price reduction.
  • The buyer may have trouble with their insurance company.
  • It can even be a deal-breaker if the potential buyer even suspects the work was not properly done.

A permit and an inspection by the local building code inspector may seem like a hassle but will pay dividends in the long run. They can be considered an investment in your property as they may save you thousands of dollars down the line. is owned and operated by Hubert Miles is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to also participates in affiliate programs with other affiliate sites.
