Load calculation
A written load calculation of existing and planned appliances, so you know whether you need more capacity at all.

Most panel projects start with a heat pump, EV charger, induction range or remodel. HAXX begins with your real electrical load and only upgrades what the numbers require.

Replacing outdated, full or recalled panels, including Zinsco and Federal Pacific.
Coordinating the utility, meter and service equipment when the home needs more power from the street.
Adding a subpanel for a garage, ADU or new circuits when the main panel is out of space.
Smart panels and circuit-sharing devices that can avoid a service upgrade in some homes.
HAXX handles the permit, the inspection and the PG&E work order.
Most Clayton panels were installed with homes built from the 1970s to the 1990s, sized for gas heat, cooking and drying. Any electrification plan in Clayton begins by measuring that panel's spare capacity.
HAXX measures what your panel already carries. Sometimes load management or a smaller circuit plan avoids a full upgrade.
When the service size changes, HAXX coordinates the disconnect and reconnect with PG&E, which serves Clayton directly.
Panel work is permitted through Clayton's arrangement with Contra Costa County's Building Inspection Division, with a final inspection before the job closes.

“Recently, my dishwasher stopped working, and they discovered it was actually an outlet issue. Not only did they diagnose it quickly, but they also fixed the outlet—saving me from calling an electrician. Reliable, professional, and skilled at handling both appliances and electrical issues.”
“I purchased a couple of ceiling fans and was reluctant due to how old my house was with old wiring so I wanted someone professional and trustworthy. They have been both!”
“Prompt and professional - they helped run a new thermostat wire through a wall and crawl space.”

A load calculation compares your current load with what new equipment adds. HAXX does this before recommending any upgrade.
HAXX coordinates the service work with PG&E and the County inspection, so you do not have to schedule each step yourself.
Not always. A load calculation shows whether your current service can carry the new appliances, sometimes with load management. HAXX recommends an upgrade only when the numbers require it.
The panel swap itself is usually one day. Permits and utility scheduling for service upgrades can add several weeks, so plan early.
