Benefits

Future-Ready Electrical Solutions

We future-proof your infrastructure with scalable panelboards, oversized conduits for adds and moves, and smart power monitoring. Our designs support networked lighting control (nLight, Enlighted), centralized emergency lighting inverters, surge protection (Type 1/2 SPD), and submetering to allocate costs across tenants. We deploy THHN/THWN-2 copper in EMT, label to ANSI/NEMA standards, and integrate power quality meters to track harmonics, voltage events, and demand peaks—all ready to tie into your building management system.

Permits and Code Compliance

Shaffer Construction manages permitting, plan check responses, and inspections end-to-end. We design to the California Electrical Code (based on NEC), California Energy Code Title 24 Part 6, CALGreen, and applicable NFPA standards (70, 70E, 110 for standby). Selective coordination and available fault current are verified for panelboards and OCPDs. We coordinate SCE meter spots and shutdown windows, provide load calculations, panel schedules, and one-line diagrams, and deliver stamped drawings when engineering is required.

Workmanship You Can Trust

Our electricians are career pros who torque terminations to manufacturer specs, maintain torque logs, and perform insulation resistance tests and thermal imaging before closeout. We use compression EMT fittings, NEMA 3R enclosures outdoors, color-coded conductors, and dedicated equipment grounds. Junction boxes are sized per fill calculations, and penetrations are sealed with fire/smoke-rated systems. Expect clean bends, straight runs, clear labeling, and a system that’s as reliable as it looks.

Customized Rewiring Plans

Every facility is unique. We begin with a detailed site walk, review as-builts, run a load study, and map out phasing so you can stay operational. Our team coordinates ceiling access, dust control, and off-hours work for retail and medical environments. We produce detailed drawings, panel schedules, and device layouts, then align sequencing with your GC, property manager, and IT provider. The result is a customized plan that fits your operations, budget, and timeline.

Frequently Asked Questions

Can my Santa Clarita business stay open during a complete rewiring?+

Often, yes. We develop a phasing plan with off-hours and weekend work, temporary power for critical loads, and a single brief planned shutdown for cutover. Retail and medical suites typically remain operational with careful sequencing and communication.

How long does a commercial rewiring take in Santa Clarita?+

Most small-to-midsize suites finish in 1–3 weeks of on-site work, depending on size, ceiling access, and panel upgrades. Permitting with the City of Santa Clarita Building and Safety Division typically takes 1–3 weeks and can run parallel to preconstruction.

Do I need a permit for panel or circuit replacements?+

Yes. The City of Santa Clarita requires permits for panelboard replacements, new circuits, feeder changes, and service upgrades. We handle plan submittals, inspections, and SCE coordination if service equipment is affected.

Will you bring our lighting into Title 24 compliance?+

Yes. When rewiring lighting, we include required controls—occupancy sensing, multi-level/dimming, daylighting where applicable—and provide acceptance testing documentation so you pass inspections and qualify for utility incentives.

How do you coordinate with Southern California Edison for shutdowns?+

We request meter releases, schedule shutdowns during low-impact hours, and ensure all prep work is complete so power is restored quickly. Our team communicates with your staff to plan around any critical operations.
