What an Electrical Panel Upgrade Involves

The electrical panel takes power from the utility and divides it into the circuits that run through your house. An upgrade replaces that panel, usually to a higher amperage rating and with more breaker spaces, along with the parts that connect it to the meter. It is one of the biggest electrical jobs a home can need, and it affects everything downstream.

Several reasons bring owners to this decision. A panel with no open spaces forces people to double up circuits. A small service, such as 60 or 100 amps, may not handle central air, an electric range, a dryer and a charger together. Certain older panel brands, including Federal Pacific and Zinsco, are known for breakers that may fail to trip, and electricians commonly recommend replacing them.

In Terrell and Kaufman County, a lot of homes combine original wiring with additions made over the years. Window units, a workshop, a well pump or an EV charger can all push an old panel past its limit. A load calculation shows what the service actually needs, and that is what we base our recommendation on, not a default size.

Signs You May Need a Panel Upgrade

No open breaker spaces, or breakers doubled up to fit more circuits.
Frequent tripping when several large appliances run at the same time.
A Federal Pacific, Zinsco or other panel with a poor safety record.
Fuses instead of breakers, or a service of 60 amps or less.
Rust, burn marks or crackling sounds at the panel.
Plans to add a charger, hot tub, workshop or addition.

What Drives Panel Upgrade Costs

Panel upgrades range widely. We quote after looking at the existing setup, because the price depends on more than the panel itself.

Amperage and size

A 200-amp panel with more spaces costs more than a like-for-like swap of a smaller one.

Service entrance work

The meter base, mast and wiring from the utility may need replacing too.

Permit and inspection

Fees and coordination with the utility are part of the job.

Condition of circuits

Damaged or undersized wiring found inside the old panel may need repair while it is open.

Electrical Panel Upgrade: Common Questions

How do I know if my panel is a Federal Pacific or Zinsco?

The brand name is usually printed on the panel door or cover. Federal Pacific panels often say Stab-Lok. If you see either name, have an electrician look at it.

How long will the power be off?

Most panel replacements take a working day, with power off for much of it. The exact time depends on the job and on the utility. We tell you the plan in advance so you can prepare.

Do I need 200 amps?

200 amps is a common size for modern homes with central air and several large appliances, but it is not required for every house. A load calculation tells you what you actually need.

Will I need a permit?

Panel replacements typically do. The requirements vary between city and county, and we will confirm what applies at your address.

Can I add an EV charger to my existing panel?

It depends on spare capacity. A charger is a large continuous load, and some older panels cannot support it without an upgrade. We can check capacity before you buy.
