Load calculation
A written load calculation of existing and planned appliances, so you know whether you need more capacity at all.
Old or undersized panel holding back a heat pump, EV charger or kitchen remodel? HAXX upgrades El Cerrito panels with permits and PG&E coordination.
Serving El Cerrito Plaza, Fairmount, Del Norte, Arlington Park and the hillside streets near the Hillside Natural Area and the rest of El Cerrito. Share your address to confirm availability.

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Replacing outdated, full or recalled panels, including Zinsco and Federal Pacific.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.
Many older El Cerrito homes still have original panels with little spare capacity. El Cerrito lists service panel upgrades as an over-the-counter permit.
A load calculation shows what the panel can carry. Some homes add a heat pump or charger with no upgrade at all.
Federal Pacific, Zinsco and worn split-bus panels show up in older housing and are worth replacing.
El Cerrito's SolarAPP+ path does not cover service panel upgrades, so a solar job with a panel change goes through the standard permit process.

“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.”
“I told him that the lights in my living room had been flickering for a while and asked if he could take a quick look. Instead of brushing it off, he immediately went to the main panel, asked a few questions, and then checked my subpanel in the garage.”

Yes. HAXX applies through the city's eTRAKiT portal, coordinates the PG&E disconnect and reconnect, and meets the inspector.
Usually about one working day for a panel swap, depending on PG&E scheduling.
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.
