Built by an Electrician Who Spent 18 Years Mastering the Trade

Samuel Hernandez-Cruz spent 18 years climbing the ranks at IBEW Local 11 — from Apprentice to Journeyman to Foreman to General Foreman, and finally to acting Superintendent on his last union project. In 2023, he founded SPD Electric Corp to build something that carries his name and his standards. 

That’s where “SPD” comes from: Superior Power Distribution. It’s the standard Samuel held himself to as a union electrician. Now it’s the standard SPD holds to on every job — from a panel upgrade in Rancho Cucamonga to a commercial tenant improvement across Southern California. 

When you call SPD, you reach Samuel directly. When you hire SPD, Samuel personally runs your project. That’s the difference between a family-owned, owner-operated contractor and the typical large electrical company.

Common Electrical Problems We Solve

Many electrical issues start small but indicate larger problems. Here are the most common issues we diagnose and fix for Southern California homeowners: 

01

Flickering or Dimming Lights

Often signals an overloaded circuit, loose connections, or aging electrical panel. Most common in older homes with original electrical service.

02

Frequent Breaker Trips

Indicates electrical demand exceeds your panel’s capacity, a circuit overload, or a faulty breaker. Often resolved with panel upgrade or circuit redistribution.

03

Burning Smell from Outlets

**EMERGENCY** — Stop using affected circuits and call immediately. Burning smells indicate damaged wiring, overloaded outlets, or electrical fire risk.

04

Federal Pacific or Zinsco Panel

These recalled panels (1950s-1980s) have known safety defects. Most insurance companies now require their replacement before they’ll provide coverage.

05

Dead or Loose Outlets

Could indicate worn-out outlets, loose wiring connections, or a tripped GFCI somewhere on the circuit. Easy to fix, but should not be ignored.

06

Need EV Charger Installation

Most Level 2 EV chargers require a dedicated 240V circuit. Older homes often need a panel upgrade first. SCE Charge Ready Home rebate available.
