Electrical Panel Replacement in Phoenix Done Right
When a panel starts tripping breakers, feeling warm to the touch, or still runs on a decades-old fuse box, it is not a small inconvenience — an overloaded or failing panel is one of the more common causes of house fires, and it only gets worse the longer it is ignored.
The trouble is that panel work is easy to get wrong. A panel gets undersized for what the home actually needs, an aging Federal Pacific or Zinsco unit gets patched instead of replaced, or the utility disconnect and permit get skipped. Cold-calling an electrician means hoping they run a real load calculation instead of guessing.
ShowUp Promise replaces that guesswork: describe what your panel is doing and we match you with a vetted, licensed, insured, background-checked electrician near you. You get an honest assessment, an upfront price, and a pro who shows up — and if they do not, the ShowUp Guarantee means you do not pay.
The Panel Replacements Phoenix Pros Handle Most
Most calls come down to a handful of jobs. The electricians in our network size and wire the right panel instead of dropping in whatever is on the truck:
- Replacing an aging, corroded, or tripping 100-amp panel with a properly sized 200-amp panel
- Removing a recalled-risk Federal Pacific Stab-Lok or Zinsco panel and replacing it safely
- Upgrading capacity for a Level 2 EV charger, rooftop solar, or a pool
- Swapping an old fuse box for a modern circuit-breaker panel
- Combining a separate meter and panel into a single meter-main combo unit
- Relocating a panel during a remodel or room addition
Why Older Panels Are a Real Risk in Phoenix Heat
Phoenix is hard on an electrical panel. Extreme summer heat pushes panels and breakers toward their thermal limits during the exact months air conditioners are pulling the most current, and older Federal Pacific and Zinsco panels are known to have breakers that can fail to trip when they should — a dangerous combination in triple-digit heat.
Corrosion is the other desert-specific problem. Panels mounted outside, near evaporative cooler lines, or exposed to monsoon humidity swings can develop rust and loose connections years before an identical panel would fail in a milder climate.
A pro who replaces panels across Phoenix homes every week recognizes these risk factors on sight, checks for heat damage and loose lugs, and gives you an honest answer on whether the panel needs replacing now or can be safely serviced.

The ShowUp Guarantee
Every electrician in the ShowUp Promise network is vetted, licensed, insured, and background-checked before they ever reach your door.

What Electrical Panel Replacement Costs in Phoenix
A standard panel swap to 200 amps typically runs $1,800 to $4,000 in Phoenix, while a full upgrade that also changes the meter base or service entrance runs about $4,000 to $7,000 or more. Utility service upgrades and difficult panel relocations add labor.
The final number tracks the amperage you are moving to, whether the meter and panel are combined, how much of the existing wiring has to be reworked, and whether the utility needs to upsize the service drop feeding your home.
With ShowUp Promise you see an all-in price and approve it before any breaker is pulled, so there are no surprise add-ons after the job. Ask for the load calculation and any equipment and workmanship warranty in writing so you know exactly what you are paying for.
Upgrade Now for an EV Charger, Solar, or a Pool
The best time to add capacity is while a pro is already replacing the panel. Common reasons Phoenix homeowners move up to 200 amps:
- A Level 2 EV charger that needs its own dedicated high-amperage circuit
- Rooftop solar with battery backup that ties into the main panel
- A pool with a variable-speed pump, heater, and lighting circuits
- A home addition, casita, or converted garage adding new circuits
- A kitchen remodel adding multiple 20-amp small-appliance circuits
- Whole-home surge protection installed directly at the new panel

What Happens on Replacement Day
The utility — APS or SRP, depending on your service area — pulls the meter first so the panel is completely de-energized before any work starts. The old panel comes out, the new panel goes in, and every branch circuit gets landed on its correct breaker.
Once the wiring is complete and the panel is closed up, the city inspector signs off before the utility resets the meter and restores power. A straightforward swap keeps the outage to a few hours during the workday.
A good pro schedules the utility disconnect, the electrical work, and the inspection back-to-back so your home is never left without power overnight, and walks you through exactly what to expect before the crew arrives.
