Main Panel Upgrades — Service & Safety, Done Right

Lights dimming, breakers maxed out, planning EV/solar? A main service panel upgrade gives you safer capacity, cleaner wiring, and room for today’s loads (EV chargers, heat pumps, induction, spas, office gear).

When to upgrade

  • Frequent trips or no free breaker spaces
  • Hot, rusted, or buzzing panel; burning smells
  • Zinsco/FPE or other obsolete gear; double-lugged breakers
  • Adding EV, heat pump, ADU, hot tub, or major appliances

What we install (options)

  • 100/125/200/225/400 A services, meter-main combos or separate meter + panel
  • Load calculation to right-size the service (no guesswork)
  • AFCI/GFCI where code requires, tamper-resistant receptacles downstream
  • Whole-home surge protector integrated at the panel
  • New grounding & bonding (ground rods, water/gas bond)
  • Subpanels for additions/garages; generator or battery/solar-ready provisions

The upgrade process

  1. On-site assessment: panel condition, service drop, grounding, space for new equipment.
  2. Written plan & pricing after the visit: amperage, panel brand, relocation if needed.
  3. Permits & utility coordination: we handle paperwork and schedule the cut-over.
  4. Professional install: safe shutdown, labeled circuits, clean terminations, new grounding/bonding, surge device.
  5. Inspection & handoff: code sign-off, updated panel schedule, photo docs, maintenance tips.

Why it’s worth it

  • Safety: modern breakers and proper bonding reduce fire/shock risk.
  • Capacity: room for EV, HVAC, and future circuits.
  • Reliability: fewer nuisance trips, cleaner voltage to sensitive electronics.
  • Resale: inspections go smoother with a modern, labeled panel.

Note: If aluminum feeders or degraded service conductors are present, we’ll replace or re-terminate with listed lugs/antioxidant and document everything.
