What commercial work do you handle?
Commercial troubleshooting and repairs
Tracing dead circuits, nuisance breaker trips, failing receptacles, and intermittent faults at commercial properties — with the least disruption to the business day we can manage.
Panel repair and service
Service and repair of existing panels and subpanels: failing breakers, hot or loose connections, buzzing gear, and tripping-breaker diagnosis. We do not perform panel upgrades, service upgrades, or panel replacements.
Dedicated circuits for equipment
New dedicated branch circuits for business equipment and other loads that should not share a circuit with everything else on the floor.
EV charger repair and troubleshooting
If a charger at a commercial property stops charging, faults, or trips its breaker, we troubleshoot the charger and the circuit, wiring, and breaker feeding it. We do not install new chargers.
Safety and code-correction work
Correcting unsafe or improvised wiring found during a walkthrough or a repair call. All work follows the 2023 National Electrical Code as adopted in California.
