Why Your Electrical Panel Matters

Your electrical panel — also called a breaker box, service panel, or main panel — is the heart of your home’s electrical system. It receives power from Southern California Edison and distributes it through circuit breakers to every outlet, switch, and appliance in your home.

When your electrical panel is undersized, outdated, or damaged, the consequences range from inconvenient (constantly tripping breakers) to dangerous (fire risk from old wiring or faulty breakers). A modern, properly sized electrical panel protects your home, supports modern electrical loads, and meets current California Title 24 and National Electrical Code requirements.

Frequently Asked Questions About Electrical Panel Services

What's the difference between an electrical panel upgrade, installation, and repair?

A panel upgrade replaces an existing panel with a higher-capacity one (typically 100-amp to 200-amp). A panel installation puts in a brand new panel where one didn’t exist (new construction, ADU, subpanel). A panel repair fixes specific problems with an existing panel like a faulty breaker or damaged component. SPD Electric handles all three.

How do I know which service I need?

Schedule a free on-site assessment. We’ll inspect your current panel, discuss your goals (more capacity, new construction, fixing a problem), and recommend the right service. Sometimes a simple breaker replacement solves the issue. Other times a full panel upgrade is needed.

How long does each panel service take?

Panel upgrade: 4-8 hours of on-site work, 2-4 weeks total project (including SCE coordination). Panel installation: 4-8 hours for new panels, longer for new construction. Panel repair: typically 1-3 hours for most repairs, same-day in many cases.

Do you pull permits?

Yes, always. California requires permits for panel installations, panel upgrades, and most major panel work. SPD Electric handles all permit applications and inspection coordination as part of every job. Skipping permits creates legal, insurance, and resale problems.

What panel brands do you install?

Eaton, Square D, and Siemens — the brands most trusted by professional electricians. These panels carry 10-year manufacturer warranties and are stocked at electrical supply houses, making future service or expansion easy.
