SAN BRUNO DETAILSPanel upgrades in
Panel upgrades in
San Bruno homes.
Much of San Bruno was built in the 1940s through the 1960s, from Mills Park to Rollingwood and Crestmoor. Original services in homes of that era were often sized well below today's loads.
01
Load calculation first
HAXX calculates the existing load before recommending an upgrade. Some homes can add a heat pump or EV charger without one.
02
Older panels
Federal Pacific, Zinsco and crowded split-bus panels still turn up in post-war homes and are worth replacing.
03
Permit and utility steps
The panel permit goes through SB Permits, and HAXX coordinates the PG&E disconnect and reconnect.

★★★★★
“The technician from Haxx immediately pointed out multiple violations of the National Electrical Code and explained that the wiring was overheating and could potentially become a fire hazard. They offered to redo the installation the correct way, pulled the proper permit, and installed the EV charger safely and professionally. The city inspection passed without any issues.”
★★★★★
“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!”

GOOD TO KNOW
Electrical Panel Upgrade in San Bruno: questions, answered.
Do I need a permit for a panel upgrade in San Bruno?
Yes. HAXX applies through the city's SB Permits portal, schedules PG&E and meets the inspector.
How long will my power be off?
Usually about one working day for a panel replacement, depending on PG&E scheduling.
Do I need 200 amps?
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.
How long does a panel upgrade take?
The panel swap itself is usually one day. Permits and utility scheduling for service upgrades can add several weeks, so plan early.
