Panels & Wiring

200 or 400 amp upgrades, Zinsco, Federal Pacific and fuse panel replacements, new circuits and rewires. All under permit.

Run the dryer, AC and a new range at once and a breaker quits. An old or undersized panel makes the whole house feel it.

First, a load calculation: math on what your house really draws. Sometimes a subpanel, smart panel or load management beats a bigger panel on cost.

Panel and wiring work

Signs your panel or wiring is tired

  • Adding an EV charger, heat pump, induction range, hot tub or battery
  • Panel says Zinsco, Federal Pacific, Stab-Lok or Challenger, or uses fuses
  • Breakers trip when big appliances run together
  • No open slots for new circuits

How panel and wiring jobs go

  1. Look and measure. We check the panel and wiring, then run the load math.
  2. Priced options. Upgrade, replacement, subpanel or load management, priced side by side.
  3. Paperwork. We file the permit and book the utility disconnect and reconnect when needed.
  4. Install and inspect. Installed to code, every circuit labeled, inspector signs off.

Panel and wiring questions

How do I know if my panel needs an upgrade?

A load calculation tells you. It's worth one if you're adding an EV charger, heat pump or battery, breakers trip in normal use, or the panel is full or a problem brand.

How much does an electrical panel upgrade cost?

$5,500 to $11,500 for most 200 amp upgrades, plus permit and utility fees. 400 amp service: $15,500 to $28,000. Same-amperage panel swap: $3,000 to $5,400. Prices updated October 2026.

Are Zinsco and Federal Pacific panels really dangerous?

Both have a documented history of breakers that may not trip when they should, and many insurers flag them. We check yours and recommend replacement.

Do I have to rewire my whole house?

Not always. Many homes rewire in stages, kitchens and baths first, or fix just the damaged section. We price each option.
