Benefits

Future-Ready Solutions Matter

We use advanced diagnostics and scalable solutions to solve today’s issue and prevent tomorrow’s. Tools include FLIR thermal imaging, insulation resistance testing, circuit tracing, and power-quality analyzers to catch hidden faults. We design repairs that support growth—adding spare capacity, labeling, and panel schedules, and preparing for EV charging, expanded POS, or new HVAC controls. When appropriate, we integrate smart lighting control (Lutron Vive, nLight) and occupancy-based sensors for reliability and energy savings.

Permits and Code Compliance

Shaffer Construction handles permitting and compliance per the California Electrical Code (CEC), NEC, and Title 24 energy standards. We coordinate with the City of Santa Clarita Building and Safety Division for plan checks and inspections, and we document torque values, conductor types, and grounding methods. Emergency egress lighting, GFCI protection in food prep areas, and signage power all receive code-focused attention. You’ll get a clear scope, photos, and compliance records for your files and property manager.

Proven Expertise and Care

We repair with commercial-grade components from Eaton, Siemens, and Schneider Electric. Conductors are copper THHN/THWN-2 in EMT or rigid steel, labeled per NEC 408.4 and 110.22. Outdoor repairs use NEMA 3R/4 enclosures, weatherproof fittings, and anti-oxidant on aluminum lugs. Our team follows NFPA 70E arc-flash safety, torque tools are calibrated, and all terminations meet manufacturer specs. The result: cooler panels, fewer trips, and longer equipment life.

Customized Repair Strategies

Every business is different. We start with an on-site assessment during your off-hours when needed, review existing one-lines, and map circuits to isolate root causes. We plan shutdowns, lockout/tagout, and temporary power to protect operations. Our recommendations balance cost, downtime, and future capacity—whether that’s adding a small subpanel, rebalancing three-phase loads, or upgrading lighting controls. You receive a clear estimate and options before work begins.

Frequently Asked Questions

Do you offer after-hours or same-day troubleshooting in Santa Clarita?+

Yes. We prioritize businesses with revenue-impacting outages and can often dispatch same day, including after-hours or early morning to avoid disrupting operations. Many issues are resolved in 1–4 hours. For larger repairs, we schedule overnight or weekend work and arrange temporary power when needed.

Will my repair need a permit from the City of Santa Clarita?+

Many like-for-like repairs don’t need a permit. However, new circuits, panel changes, service upgrades, and parking lot or signage wiring typically do. We’ll advise you on the spot, submit applications to the City of Santa Clarita Building and Safety Division when required, and coordinate inspections to minimize downtime.

Our 277V lighting keeps tripping—what’s the cause and fix?+

In Santa Clarita’s commercial spaces, 277V trips often come from ground faults in fixtures, damaged conductors, or failing LED drivers. Heat and long runs can aggravate the problem. We isolate circuits, megger test conductors, and inspect fixtures to pinpoint failures. Repairs may include replacing drivers/ballasts, repairing wiring, or rebalancing loads to stop nuisance trips.

Can you troubleshoot rooftop HVAC power and VFD faults during summer heat?+

Absolutely. We regularly service rooftop units across Valencia and Saugus. We verify supply voltage, check fuses, contactors, and overloads, inspect terminations for heat-related loosening, and read VFD fault codes. We correct wiring issues, replace failed components, and ensure proper ventilation and surge protection to improve reliability during 90–105°F weather.
