Electrical Panel Replacements in Mesa, Scottsdale, and the Phoenix Valley

Every circuit in your home runs through the electrical panel. When it starts to fail, runs out of breaker space, or can no longer carry the load, everything downstream suffers: breakers trip, lights flicker, AC compressors short-cycle, and EV chargers can't get enough power to charge overnight. At The Wire Guy Electric, panel work is one of the things we do most often. Arizona ROC #365306, fully insured, and coordinated directly with APS or SRP from start to finish.

What We Do

  • 200-amp like-for-like replacement. The job we do most often. Old 200-amp panel comes out, new Square D, Siemens, or Eaton panel goes in. Same service size, fresh equipment, all new breakers.
  • Full service replacement (all-in-one meter base and panel). When the meter base itself is corroded, undersized, or out of spec, we replace the whole assembly as a single combo unit.
  • Recall-brand replacements. Old Zinsco, Federal Pacific (FPE), Challenger, and Pushmatic panels are a known fire hazard. If you have one, it needs to come out. We replace with new Square D, Siemens, or Eaton panels rated for today's loads.
  • Service upgrades (200 to 400 amp). Adding a pool, hot tub, EV charger, casita, or second AC unit can push your home past what existing service can handle. We do the load calculation, coordinate with SRP or APS for the meter pull, and get you upgraded.
  • Panel relocations. Moving a panel from inside a garage to an exterior wall, or shifting it to accommodate a remodel. Includes new meter base, service conductors, grounding system, and utility coordination.
  • Subpanel installs. Sometimes the right answer isn't a full main upgrade. Adding a subpanel for a new garage workshop, casita, or EV charger circuit is often faster and cheaper.

What It Costs

We price panel work at a flat rate with no hidden fees. Ask us for a free quote. Full breakdown of pricing and what drives the number is in our Arizona panel replacement cost guide.

APS and SRP Coordination

A real panel replacement requires the utility to pull the meter, and in many cases temporarily disconnect service at the pole or transformer. We coordinate that for you. We submit the service request to APS or SRP, schedule the meter pull around your work window, and get you back on power the same day whenever possible.

  • Clean work. Labeled breakers, straight wire runs, proper torquing, and no loose neutrals. When you open your panel, it should look like a textbook photo.

    William Pascal Google review · Feb 24, 2026

  • We have used Wire Guy in the past. We had such a great experience previously, so when we had another project, we called them, again. This experience was equally as great. Rhett showed up right at the beginning of the scheduled "window" time, did our installation promptly and quickly, and cleaned up afterwards. He is friendly, knowledgeable, and professional. We enthusiastically recommend Wire Guy Electric for any electrical need,

Questions

Questions about panel replacements

From our FAQ.

All questions on our FAQ

How do I know if my electrical panel needs to be upgraded?

If your breakers trip frequently, if your lights flicker when large appliances kick on, if you still have a fuse box, or if your panel is more than 25 years old, it's worth having it looked at. Homes with 100-amp panels that are trying to run modern appliances, AC systems, and EV chargers are usually overdue for an upgrade. We also strongly recommend replacing any Federal Pacific or Zinsco branded panels, as these have well-documented safety issues. We offer free estimates and will give you an honest answer on whether you actually need the upgrade or not. Read more on our panel upgrades service page.

What is the difference between a 100 amp and 200 amp electrical panel?

It comes down to how much electricity your home can handle at once. A 100-amp panel was standard in older homes and works fine for smaller properties with basic electrical needs. A 200-amp panel is the current standard for new construction and can support modern demands like central AC, electric dryers, pool pumps, EV chargers, and multiple large appliances running at the same time. Most homes in the Phoenix valley that were built before the early 2000s have 100-amp panels. If you're adding major appliances or doing a remodel, upgrading to 200 amps is usually the smart move. Check out our detailed panel upgrade cost guide for more info.
