HILLSBOROUGH DETAILSPanel and service
Panel and service
upgrades in Hillsborough.
Many Hillsborough homes have subpanels added over decades of remodels, and some original equipment is past its life. Electrifying a large house starts with knowing what the service can carry.
01
Load calculation first
HAXX works out the actual household load before suggesting any upgrade. Load management can sometimes avoid one.
02
Older and mixed equipment
Federal Pacific, Zinsco and worn subpanels from past additions are worth replacing. HAXX maps every panel in the house.
03
WestLight panel bonus
WestLight Energy (formerly Peninsula Clean Energy) lists a panel upgrade bonus when paired with a heat pump rebate; the main panel must be 200 amps or less after the upgrade. Confirm with WestLight.

★★★★★
“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 Hillsborough: questions, answered.
Do I need a permit for a panel upgrade in Hillsborough?
Yes. Electrical work needs a Town permit. HAXX applies through eTrakit, coordinates with PG&E and meets the inspector.
Does every panel upgrade qualify for the WestLight bonus?
No. WestLight ties the bonus to a heat pump HVAC or water heater rebate and limits it to main panels of 200 amps or less after the upgrade. Confirm eligibility with WestLight Energy.
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.
