Local notes
A typical 100A to 200A upgrade starts with a load calculation: HVAC, range, dryer, well pump, and any EV charger.
Visalia, Tulare, Porterville, and Dinuba usually issue their own electrical permits. Unincorporated Tulare County goes through the county building division (RMA).
Southern California Edison often needs a same-day service disconnect so the meter can come off while the panel is swapped.
Old Federal Pacific and Zinsco panels are a common reason homes in the Valley get upgraded, not a style choice.
Questions people ask
How do I know if I need a panel upgrade?
Frequent breaker trips, flickering lights, a burning smell at the panel, a panel older than 25 years, or adding an EV charger or HVAC are the usual signs.
How long does a panel upgrade take?
A straightforward residential swap is typically 4–8 hours on site, plus a final inspection before the meter is resealed. Commercial work takes longer.
Do I need a permit for a panel upgrade?
Yes. In California a C-10 pulls the permit and meets the inspector. That should be written into the bid.
