01 · Panel upgrades
100 A to 200 A, in a day.
The most common job we do in Sunnyvale. A new 200 A main panel, every circuit landed on a new breaker, grounding electrode system brought to current code, and the meter base replaced if PG&E asks for it. We handle the PG&E service-change request and the city permit; you handle nothing.
