Electrical Panel Upgrades
ELECTRICAL PANEL UPGRADES IN Phoenix, AZ
Independent testing found Federal Pacific Stab-Lok breakers failing to trip up to 60% of the time in some tests, and Zinsco panels carry similar concerns, which is why home inspectors flag both brands on sight. MaxCharged handles electrical panel upgrades in Phoenix, AZ: 200-amp service upgrades, like-for-like replacement of aging or recalled panels, subpanels, circuit reconnection and labeling, solar and battery interconnection readiness, and the utility and permit coordination that comes with each job. Tesla-certified and licensed under Arizona ROC #CR11-346079.
THE PANEL DECIDES WHAT THE REST OF THE HOUSE CAN DO.
Every appliance, charger, and air handler in the house pulls through one box on the garage wall. When that box is a 100-amp panel from the 1980s, adding a Level 2 charger means either careful load management or a new service. We run the numbers first, because a panel upgrade is a real project and you should know if you need it.
When the answer is yes, the job is planned like a project: utility disconnect booked, express permit filed, circuits mapped, and the power back on the same day it went off.
✓ 200-amp service upgrades
✓ Federal Pacific and Zinsco replaced
✓ Express permit filed for you
✓ APS and SRP disconnect scheduled
ELECTRICAL PANEL UPGRADES
MORE VALLEY HOUSES ARE OUT OF PANEL SPACE THAN OUT OF POWER.
A full panel and an overloaded panel are different problems. Plenty of homes have 200 amps of service and 40 breaker positions already spoken for, and others have a half-empty 100-amp panel that cannot carry a charger and a heat pump on a July evening. We read the main breaker, run the load calculation, and tell you which problem you have, because one fix is a subpanel and the other is a new service.
PHOENIX HANDS OUT THE PERMIT OVER THE COUNTER.
Phoenix, AZ treats a residential service upgrade up to 200 amps as an express permit, issued over the counter rather than through a plan review, so the paperwork rarely holds a job up. The utility is the longer lead: APS or SRP schedules the meter disconnect 1 to 2 weeks out, the house is without power for 4 to 8 hours, and most upgrades finish in 1 day.
NOBODY GETS A NEW PANEL THEY DO NOT NEED.
In 10 years of EV charger work we have talked many homeowners out of a panel upgrade. A load calculation under the rating, a load-management device on the charger, or a subpanel off a healthy main panel often does the job with less disruption. When the panel is a Federal Pacific, a Zinsco, or a 60-amp relic, we say so and show the math. Want to know which side your house lands on?
WHY CHOOSE US FOR ELECTRICAL PANEL UPGRADES.
A Load Calculation, Not A Pitch
Your upgrade decision comes from a written NEC load calculation of your square footage, fixed appliances, HVAC, and planned additions. If the numbers say your existing service can carry the charger, you hear that first, and the upgrade waits.
Power Back On The Same Day
A panel change means the meter is pulled and the house goes dark. We stage every conductor, breaker, and label in advance so the work fits inside the utility window, and you cook dinner on the new panel that same night.
Breakers That Trip When Asked
Replacing a Federal Pacific or Zinsco panel is about more than capacity. The new panel carries breakers listed for it, tightened to specification, that open the instant a fault happens. That is the whole point of a breaker, and it has been missing.
Every Circuit Labeled Correctly
Each branch circuit is traced to its room before it is reconnected, then named on the new directory in plain language. No more flipping 6 breakers in a row to find the one that kills the bedroom outlets at bedtime.
Room For What Comes Next
Your new panel leaves open positions and bus capacity for the charger, the spa, or the battery you are thinking about. Interconnection space for solar is planned in now, so the next contractor does not need to open the wall again.
Utility And City Handled Together
The disconnect request, the express permit, the inspection, and the reconnect all have to line up on one calendar day. We book the utility, file with the city, and meet the inspector, so your only task is picking the date.
WHAT WE UPGRADE
OUR ELECTRICAL PANEL UPGRADES WORK
Panel work comes in 6 shapes, from a full service upgrade to a subpanel that solves a space problem without touching the meter. The survey tells us which one applies to your house, and the estimate prices only that.
200 AMP
200-Amp Service Upgrades
The service entrance conductors, meter socket, main panel, and grounding electrode system are replaced together and sized for 200 amps. Branch circuits stay put. The result is capacity for a charger, a heat pump, and an induction range at once.
LIKE FOR LIKE
Panel Replacement
Same amperage, new hardware. When the issue is age, a recalled brand, corrosion, or a bus bar that no longer holds a breaker, the panel gets replaced at its current rating with no utility change. It is quicker and removes the actual hazard.
SUBPANELS
Subpanel Installation
A feeder from the main panel to a garage or workshop panel adds breaker positions where there were none. Sized by the load calculation and bonded correctly, it often replaces a full upgrade for a house that is out of space, not amps.
LABELED
Circuit Reconnection and Labeling
Before the old panel comes off the wall, each conductor is identified and tagged. On the new panel every breaker is landed, tightened, and named on the directory in words you will recognize, so nobody guesses in the dark during the next trip.
SOLAR READY
Solar and Battery Interconnection Readiness
Solar inverters and battery systems need a landing spot, a properly rated backfeed breaker, and bus capacity the code allows. We build those provisions into the new panel and coordinate with your solar contractor so the interconnection is a hookup, not another panel.
UTILITY
Utility and Permit Coordination
Express permit to the city, disconnect and reconnect booked with APS or SRP 1 to 2 weeks ahead, inspection scheduled for the same afternoon. You get one date on the calendar, one contact for everything, and no phone tree to sit in.
THE WORD ON OUR WORK
WHAT OUR CLIENTS SAY.
Upgrade jobs get written up more than most, because homeowners remember the day the power went off and came back by dinner. The reviews mention the labeled directory, the clean conduit, and the inspection that passed on the first visit. Read what people across the Valley had to say.
Common questions
FREQUENTLY ASKED QUESTIONS.
Questions about panels come up after an EV purchase or a home inspection report. These are the ones we hear most, answered plainly so you know what an upgrade involves before anyone quotes one.
How do I know if I need to upgrade my electrical panel?
Frequent breaker trips, flickering when big loads start, no open breaker positions, 60- to 100-amp service, or a Federal Pacific or Zinsco label are the signs. A load calculation settles the question, because a full panel and an overloaded panel need different fixes.
How can I tell whether my service is 100 or 200 amps?
Look at the main breaker in the panel; the number stamped on the handle is the service rating. A pair of 100-amp mains is not 200-amp service. MaxCharged confirms the rating and the meter socket on every survey in Phoenix, AZ.
Can I replace my panel without upgrading to 200 amps?
Yes. A like-for-like replacement at the existing amperage is common when the issue is age, corrosion, or a hazardous brand rather than capacity. The utility service stays the same, the permit is simpler, and the fix addresses the actual safety problem.
Do I need to rewire my house for a 200-amp upgrade?
No. A 200-amp upgrade replaces the service entrance, the meter socket, the main panel, and the grounding, while the branch circuits behind the walls stay untouched. Each existing circuit is simply reconnected to a new, listed breaker and labeled.
How long is the power off during a panel replacement?
Plan on 4 to 8 hours without power, from the time the utility pulls the meter to the time the inspector clears the reconnect. Most upgrades finish in 1 day. Keeping the refrigerator closed carries it through that window without trouble.
What is the lifespan of an electrical panel?
Most panels last about 25 to 30 years. Heat, moisture, corrosion at the bus, and years of breaker cycling shorten that. In a hot garage, a panel from the early 1990s is due for a close inspection now and likely for replacement soon.
Are Federal Pacific panels dangerous?
Independent testing found Federal Pacific Stab-Lok breakers failing to trip up to 60% of the time in some tests, which means a fault can cook wiring without opening the circuit. Replacement is the standard recommendation, and MaxCharged does that work across Phoenix, AZ.
Will a new panel work with solar or battery storage?
Yes, when it is planned that way. The new panel can carry a backfeed breaker for an inverter, a landing for battery equipment, and the bus capacity the code allows, but coordination with your solar contractor is needed so the hardware matches.
HOW WE WORK
FROM LOAD CALCULATION TO LIGHTS BACK ON, HERE IS HOW.
STEP 01
Read The Panel And The Load
We check the main breaker rating, the panel brand, the meter socket, the grounding, and the open positions, then run the load calculation with your planned additions included. The estimate comes out of that visit.
STEP 02
Choose The Right Fix
Full 200-amp upgrade, like-for-like replacement, or a subpanel. You see the calculation and the reasoning behind each option, and you pick with the numbers in front of you rather than on faith in a salesperson.
STEP 03
File The Permit, Book The Utility
The express permit goes in as soon as you approve, and the disconnect is requested from APS or SRP, which books 1 to 2 weeks out. That utility date becomes the installation date on your calendar.
STEP 04
Swap The Panel Inside The Window
With the meter pulled, the old panel comes off, the new service equipment and grounding go in, and every branch circuit lands on a listed breaker, tightened to specification. The work is staged to finish in 1 day.
STEP 05
Label, Inspect, Reconnect
Every breaker gets a plain-language directory entry, the inspector signs off, and the utility reconnects the service. Lights back on, usually the same afternoon, with a certificate of completion in your hand before we go.
STEP 06
Owner Sign-Off Before We Roll
The owner inspects the finished panel before we pack up, checks the torque marks and the labels, and walks you through what changed. Then we sweep out the garage, load the truck, and go.
