Load calculation
A written load calculation of existing and planned appliances, so you know whether you need more capacity at all.
Short on capacity for a heat pump, EV charger or induction range? HAXX upgrades and replaces electrical panels in Belvedere and coordinates with PG&E.

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Replacing outdated, full or recalled panels, including Zinsco and Federal Pacific.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.
Older Belvedere homes often have small or outdated panels sized for gas appliances. Electrifying usually starts with a load calculation, not a new panel.
HAXX calculates existing and planned loads to see whether the current service can carry new equipment with load management.
Meters on steep or narrow lots, and corrosion on older equipment near the water, are checked when planning the upgrade.
HAXX files the electrical permit with the City of Belvedere Planning and Building Department and handles PG&E coordination when the service size changes.

“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.”

A load calculation shows whether the current service has room. Some homes can avoid an upgrade with load management or smaller-draw equipment.
HAXX coordinates with PG&E for disconnect, reconnect and service changes, and with the city for the electrical permit.
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.
