Main Electrical Panel Upgrades in San Ramon, Danville, Walnut Creek & the East Bay
Crow Canyon Electric upgrades main electrical panels for homes and businesses in San Ramon, Danville, Blackhawk, Walnut Creek, Berkeley, Oakland, Alameda, Livermore, Pleasanton and Fremont. A new main panel adds capacity for EV chargers, ADUs, solar and air conditioning, and replaces old equipment that has reached the end of its life.
Main Panel Upgrades done properly, start to finish
The main panel is the heart of the electrical system: all power from the utility comes through it. Older panels were designed for far fewer circuits than a modern house uses. Add an EV charger, a heat pump, a kitchen remodel or an ADU, and the panel runs out of room or capacity long before the wiring does.
A main panel upgrade replaces the panel, and when needed the service equipment around it, with modern breakers, clear labeling and more capacity. The work is coordinated with your city’s permit and inspection process and with your utility when the power needs to be shut off. Our photos show panels before and after, including the careful wire dressing inside.
