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Replacing outdated, full or recalled panels, including Zinsco and Federal Pacific.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.
Plenty of Moraga homes from the 1960s and 1970s still have their original 100-amp service. Recent county permit logs for Moraga show 100-amp to 200-amp upgrades among the routine filings.
An NEC load calculation shows whether you need a bigger service at all. Load management sometimes lets a project fit on the existing panel.
Federal Pacific Stab-Lok and Zinsco panels from this building era are still found in town and are good candidates for replacement.
Contra Costa County lists panel upgrades among projects that need a building permit. HAXX files it and schedules PG&E for the disconnect and reconnect.

“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. Contra Costa County permits Moraga electrical work, and HAXX applies through the county's ePermits Center.
Expect most of one working day. PG&E's disconnect and reconnect times set the exact window.
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.
