Frequently asked

Panel Upgrade Questions, Answered

Straight answers about cost, timing, permits, and whether your panel needs a repair or a full replacement, from a licensed Hollister electrical team.

Q1

What affects the cost of a panel upgrade?

The biggest factors are the new panel's amperage, whether the main service line and meter need upgrading too, and how much rewiring or permit work the local utility requires. Panels going from an old 60 or 100 amp fuse box to a 200 amp breaker panel typically involve more labor than a straightforward breaker swap. Homes needing a subpanel for an EV charger, generator or addition will see added cost for that extra wiring and circuit work.

Q2

How long does a panel upgrade take?

Many straightforward panel swaps are completed in a single day once the permit and utility coordination are in place. Jobs that involve a full service size increase, meter relocation, or utility company scheduling for a temporary power shutoff can take longer. We'll walk you through the expected sequence after assessing your current panel and home's electrical needs.

Q3

Do I need a permit or inspection for a panel upgrade?

Yes, panel upgrades in Hollister and San Benito County require a permit and a final inspection because they involve changing your main electrical service. We handle the permit paperwork and coordinate with the local utility and inspector so the job meets code from the meter to the breakers.

Q4

What signs mean I need a panel upgrade?

Breakers that trip often, a panel with fuses instead of breakers, warm or discolored panel covers, flickering lights when appliances start, and a lack of open slots for new circuits are all signs your panel may be undersized or aging out. If you're adding an EV charger, generator, or hot tub, that's often the trigger that reveals a panel is already near its limit.

Q5

Should I repair my panel or replace it entirely?

A repair makes sense for an isolated issue like a bad breaker or loose connection in a panel that's otherwise in good shape and has enough capacity. Full replacement is the better call when the panel is outdated, undersized for your household's load, still running fuses, or shows signs of wear throughout, since patching an aging panel usually just delays the same decision.

Q6

Can I upgrade my own panel or do I need a licensed electrician?

Panel work should be done by a licensed electrician. It involves working at your main service connection, meets strict code requirements, and requires permitted inspection, so DIY work can create safety hazards and complications when you sell the home or file an insurance claim.
