100A to 200A Outdoor Panel Upgrade with Stucco Repair in San Jose | Drummond Electric
Location: San Jose, CA · Completed: May 2026 · Type: Service upgrade, overhead

The situation
The homeowner was planning a kitchen remodel and an EV charger. Their 100A outdoor panel, fed by an old 1-1/4" service riser, didn’t have the capacity for either. A remodeled kitchen adds circuits for appliances, lighting and countertop outlets, and a Level 2 charger needs its own 40–60A circuit. Upgrading to 200A first meant both projects could go ahead without overloading the service.

What we did
Submitted the PG&E application and scheduled the disconnect and reconnect
Pulled the permit with the City of San Jose
Cut the stucco and removed the old 100A panel
Replaced the 1-1/4" riser with a new 1-1/2" rigid metal conduit service riser
Pulled new 2/0 copper service-entrance conductors, sized for a 200A residential service
Installed a new 200A Square D Homeline panel with 20 spaces / 40 circuits
Added a whole-home surge protector
Installed the grounding electrode system and water pipe bond to current code
Passed City of San Jose inspection, and PG&E reconnected service
Brought in a stucco contractor to patch and finish the wall professionally
Result
The home went from 100A to 200A, with capacity for the new kitchen and a Level 2 EV charger, plus surge protection and up-to-code grounding. The stucco around the new panel was patched by a professional, so the wall looks finished, not patched over.
