Services We Provide
Main Panel Replacement
We replace recalled and obsolete panels (FPE, Zinsco, Pushmatic) with modern, serviceable gear.
Service Upgrade (100A → 200A)
We coordinate full service upgrades with PG&E — meter-main, weatherhead, and mast work included.
Sub-Panel Installation
We install sub-panels for ADUs, garages, workshops, EV charging, and high-load appliances.
NEC 220 Load Calculation
We size service to the real load — not the default — so capacity matches future electrification plans.
Authorized SPAN Smart Panel Installer
Upgrade once, future-proof for everything: EV chargers, solar, battery backup, and per-circuit app control with a SPAN Smart Panel.
Not just new equipment — a system done correctly.
Main Panel Replacement
Federal Pacific, Zinsco, Pushmatic, and certain Challenger panels are documented fire hazards. Replacement is a safety upgrade, not just a capacity upgrade — and a known item on most home inspection reports.
Service Upgrade (100A → 200A)
We coordinate full 100A→200A and 225A service upgrades with PG&E, including meter-main, weatherhead, mast, and grounding work. Permits are pulled, inspections are scheduled, and the work is documented.
Sub-Panel Installation
We install sub-panels for ADUs, garages, workshops, EV charging, and high-load appliances. Smart load management is deployed where capacity is tight so projects can proceed without a full service change.
NEC 220 Load Calculation
ABC Service performs NEC 220 load calculations against your real and planned loads — heat pumps, induction, EV charging, HPWH. A panel upgrade should be sized for what comes next, not just what plugs in today.
Why this is worth doing right.
Capacity for electrification
Heat pumps, induction, EV charging, and HPWH all need real capacity. A panel upgrade unlocks the rest.
Removes known fire risk
Older and recalled panels are documented fire hazards. Replacement is a safety upgrade, not just capacity.
Code compliance
Modern panels include the AFCI, GFCI, and bonding required by current code — not by 1985 code.
Resale value
An inspected 200A+ service is documented value at sale and removes a common inspection-report flag.
