How does El Cajon's climate affect this service?
El Cajon faces the most extreme summer heat outside the desert (100-115°F peaks) combined with the oldest tract housing inventory in East County. Heat stress on aging service equipment, Federal Pacific and Zinsco panel replacement, and aluminum branch wiring remediation drive the highest weekly call volume in our service area.

How much does a 200-amp panel upgrade cost in San Diego?
A straightforward 100A → 200A upgrade in a single-family home runs $2,800 to $4,200 installed, including the permit, new meter socket, main breaker, grounding, and SDG&E coordination. Long meter-to-panel runs, exterior weatherheads, or buried service feeders add cost. Ask for a written quote before work starts.
Do I need a permit for a panel upgrade?
Yes. Every main panel replacement requires a permit through your city or county building department. Electricians in our network pull it, schedule the SDG&E disconnect, and stay on site through inspection. Working without a permit voids your homeowners insurance and creates problems at resale.
