Electrical Panel Upgrades in Fresno
Jack Surabian Electric works out of 4647 S Cherry Ave in Fresno, and main panel upgrades are one of the most requested jobs we handle in the city. Fresno housing stock spans nearly a century, from Tower District bungalows still fed by 60 and 100 amp services to Woodward Park and Fig Garden homes where the original 125 amp panel now supports a heat pump, a pool pump, a second refrigerator, and a Level 2 EV charger.
Your main panel is the distribution point for every circuit in the building. When it is undersized, obsolete, or full, the whole system inherits that limitation: breakers trip during heat waves, additions cannot be permitted, and modern safety devices like AFCI and GFCI breakers may not even be available for the equipment you have. A panel upgrade resolves the bottleneck at the source rather than working around it.
What a Properly Sized Fresno Panel Delivers
- Headroom for future load
- Modern AFCI and GFCI protection
- Room for new circuits
- Reliable summer AC performance
- Permit-ready documentation
- Cleaner grounding and bonding
- Solar and EV readiness
- Higher appraisal confidence
When to upgrade
Signs a Fresno Home Needs a Panel Upgrade
Some panels fail loudly and some simply quietly limit what your home can do. These are the conditions that bring Fresno homeowners to us most often.
- A 60, 100, or 125 amp service feeding a home that has since added central air, a pool, or an EV charger
- Federal Pacific Stab-Lok, Zinsco, or Sylvania panels that are known to fail to trip under fault
- Breakers that trip repeatedly during July and August air conditioning load
- A full panel with no open spaces, or one packed with tandem breakers
- Fuse boxes, split bus panels without a single main disconnect, or panels with visible rust and heat marks
- A remodel, ADU, kitchen addition, or solar interconnection that requires more capacity
- Burning odors, buzzing, or warmth at the panel cover
How a Fresno Panel Upgrade Is Performed
We begin with a load calculation rather than a guess. Existing appliances, HVAC equipment, planned EV charging, and square footage determine whether 200 amps is right or whether a larger service is justified. We then review the meter, service entrance conductors, grounding electrode system, and panel location for clearance and code compliance.
The upgrade itself is permitted through the City or County of Fresno, coordinated with PG&E for the power cutover, and inspected on completion. We set the new panel, transfer and label every circuit, correct the grounding and bonding, install required arc fault and ground fault protection, and restore power the same day in most residential cases.
Upgrade the Panel Before Summer Load Finds the Weak Point
Fresno electrical systems are tested hardest in the middle of summer, which is exactly when an aging panel is most likely to fail. If your panel is original, full, or tripping, call Jack Surabian Electric for an honest assessment and a written scope.
