Common questions for Electrical Panel Upgrade in Castroville
Do I need to upgrade from 100A to 200A?
You need to if your load calc exceeds your current service capacity. Most homes built before 1985 have 100A or 60A service and exceed it the moment you add an EV charger, a hot tub, central AC, or a whole-home generator. We run a real load calc and tell you in writing whether the upgrade is required or recommended.
How much does a panel upgrade cost?
Cost depends on amperage (200A), whether the service entrance conductor needs replacement, the panel brand and breaker count, grounding updates, and the utility coordination required. We quote in writing after the site walk so the number is fixed before work starts.
How long is the power off during a panel upgrade?
Typically four to six hours during the utility cut and reconnect window. We schedule the cut early, complete the panel swap, and call for the utility reconnect once the inspection clears. Some larger upgrades or service-entrance changes run longer.
Do you pull the permit for a panel upgrade?
Yes. Service upgrades require a permit in every jurisdiction we work, and we pull it in the homeowner or property owner name. We schedule any inspection and the utility reconnect, and close the permit when the the work is complete.
Will my existing breakers transfer to the new panel?
Sometimes. If the existing breakers are the same brand and current generation, we can transfer the compatible ones. AFCI and GFCI breakers usually transfer cleanly when the manufacturer is the same. Older, brand-mismatched, or recalled breakers (FPE Stab-Lok, Zinsco) get replaced with new code-compliant breakers.
