Does my electrical panel need to be upgraded?

If your panel feels warm, breakers trip often or you are adding load, have it checked. Circuit breaker panels typically last 25 to 40 years, and a panel can be too small long before it wears out.

  • A warm panel

    Heat at the panel can mean an overloaded circuit or a connection that is failing.

  • Breakers that trip or crackle

    Frequent trips or odd sounds point to overload or a worn breaker.

  • Dimming or flickering lights

    Lights that dim when equipment starts suggest the system is struggling with the load.

  • No open breaker spaces

    If there is no room for a new circuit, the panel is already full.

  • An old or recalled brand

    Zinsco and Federal Pacific panels are widely flagged by inspectors, so have them evaluated.

  • New load coming

    An EV charger, solar system, air conditioner, addition or new equipment can outgrow an older panel.

What is an electrical panel?

The electrical panel is the main point where power from the utility connects to the wiring inside your building. It is also called a breaker box, main breaker panel, fuse box, load center or distribution panel. Each breaker in it protects one circuit, and the panel as a whole sets how much power the building can use at once.

What happens during a panel upgrade?

  1. 01

    Assess the panel

    We check the panel's condition, open spaces, signs of overheating and the connected load, and whether the service feeding it can carry more.

  2. 02

    Plan and permit

    We agree on the panel size and scope with you, pull the permit and schedule with the city and the utility (APS or SRP) when needed.

  3. 03

    Replace the panel

    Power is shut off while the panel is swapped. We schedule it to disrupt you as little as possible, and for businesses around operating hours. Bonding and grounding are corrected where needed.

  4. 04

    Test and inspect

    We test the new panel, label the circuits and have the work inspected so you can use it with confidence.

Do I need a panel upgrade or a service upgrade?

The panel is the box inside your building. The service is the connection from the utility, including the meter and the main feed. If the service is too small, a bigger panel alone will not give you more usable power.

We check both before recommending anything. If the service needs work, see our service upgrades. If you are not sure what the building can carry, a load study measures it first.

Panel upgrades for homes, businesses and multifamily properties

  • Homes

    Older homes often have small, worn or recalled panels, and EV chargers, solar, air conditioning and remodels add load. Aluminum wiring gets checked at the same time.

    Residential electrical services
  • Businesses

    We plan around tenants and operating hours, and size the panel for new equipment, code repairs and expansion.

    Commercial electrical services
  • Multifamily

    We replace aging distribution and unit panels and work with property managers on access and scheduling.

    Electrical inspections

What panel brands do you replace?

We replace panels from Square D, Siemens, Cutler Hammer, Eaton, Westinghouse, Crouse Hinds, Murray, Zinsco and Federal Pacific. A panel upgrade often goes together with breaker replacement or aluminum wire repair.

Electrical panel upgrade questions

How much does an electrical panel upgrade cost?

The price depends on the panel size in amps, the condition and brand of the old panel, how much wiring or grounding needs correcting, permit and utility requirements, and whether the service also needs an upgrade. We quote after we look at the panel. Call (602) 564-1144 or request a consultation with a short description.

Will the power be off during a panel upgrade?

Yes. Power to the building has to be off while the panel is swapped. We plan it with you so it happens at the time that disrupts you least, and for businesses we work around operating hours.

Do I need a bigger panel for an EV charger or solar?

Often. An EV charger, solar system, new air conditioner or addition adds load, and an older panel may not have the capacity or the open spaces. We check the panel and, if needed, run a load study before recommending a size.

Should I replace a Zinsco or Federal Pacific panel?

We recommend having it evaluated. Inspectors widely flag these older panels because their breakers may not trip when they should. We inspect yours and tell you whether replacement makes sense.

Does a panel upgrade need a permit?

Yes. Panel replacement needs a permit and an inspection from the city, and we coordinate the scheduling with the city and the utility.
