Our Work
Benefits
Modern Protection Technology
We design surge protection to grow with your home’s technology. Shaffer Construction specifies Type 1 or Type 2 UL 1449 4th Edition SPDs with high surge current ratings, SCCR compatibility with your panel, and proper MCOV selection. We integrate protection for solar inverters, battery systems, and EV chargers, and can add data/coax protection for home offices and media rooms. The result is a scalable, layered defense that stays effective as you add loads and smart devices.
Code-Compliant Installations
Our licensed electricians handle permitting with the City of Culver City Building and Safety Division, coordinate inspections, and label equipment per CEC 110.22. We follow California Electrical Code grounding and bonding requirements (CEC Article 250), torque terminations to manufacturer specs, and install only UL-listed devices. If a panel upgrade or grounding electrode enhancement is needed, we include code-calculated conductor sizing and clear as-built documentation.
Skilled, Trusted Electrical Experts
We install surge devices from top manufacturers (Eaton, Siemens, Leviton, Square D), using copper bonding jumpers, listed clamps, and 5/8"×8' copper-clad rods when needed. Leads are routed as short and straight as possible to minimize let-through voltage, with ferrules, anti-oxidant on AL conductors, and torque-verified terminations. We test grounding performance and verify line-to-ground integrity so your SPD performs as specified when it matters most.
Personalized Assessment & Design
Every Culver City home is different. We begin with a panel and grounding assessment, evaluate connected equipment (HVAC, EVSE, solar), and measure clearances for mounting. We size SPDs to your service (100A–400A, 120/240V split-phase) and coordinate protection with downstream equipment. If your home office or AV rack needs additional data/coax protection, we integrate that into a single, seamless plan and provide a clear scope, price, and schedule.
What We Offer
Frequently Asked Questions
Do Culver City homes really need surge protection if lightning is rare?+
Yes. Most damaging surges here come from utility switching, faults, or large equipment cycling—especially with solar, batteries, and EV chargers. A panel-mounted SPD clamps those transients before they reach sensitive electronics, protecting appliances, HVAC controls, and home office equipment even without frequent lightning.
Will I need a permit in Culver City for a whole-house surge protector?+
Most installations require an electrical permit from the City of Culver City Building and Safety Division. Simple, like-for-like SPD installs are typically quick to approve; combined panel or grounding upgrades may add plan review time. We handle the permit and meet the inspector so the process is easy for you.
How long does the installation take and will my power be off?+
A typical installation takes a half day on site (about 2–4 hours), with power off for a portion of that time while we connect the SPD and verify grounding. We schedule the outage window with you and restore service as soon as testing is complete. Most homeowners experience minimal disruption.
Will this protect my solar system and EV charger?+
Yes, we coordinate protection with your solar inverter and EVSE. The main SPD reduces surges entering the home, and we can add AC-side protection near the inverter or charger if your equipment or layout warrants it. Proper grounding and bonding are key to ensuring both solar and EV systems are protected.
My home has an older panel (Zinsco/FPE). Can you still install surge protection?+
We’ll evaluate the panel’s condition and short-circuit rating. In many cases, upgrading unsafe legacy panels is recommended to ensure reliable surge performance and overall safety. We can provide options for a modern, code-compliant panel and integrate surge protection during the upgrade.
Do I still need point-of-use power strips with a whole-home SPD?+
A whole-home SPD handles large transients at the service, but sensitive electronics may benefit from quality point-of-use protectors for an added layer. We recommend a layered approach: service-level SPD plus reputable point-of-use devices for computers, networking gear, and AV equipment.
Our whole-building surge protection service is designed for how Culver City lives today: streaming, remote work, EV charging, and smart everything. We start with a focused assessment, size the right UL-listed SPD for your service, and make sure grounding and bonding are ready to do their job. The installation is typically a half day, and most homeowners experience only a brief, planned outage. We finish by testing, labeling, and walking you through what to look for so you know your home is protected. Have an older panel, solar, or an EV charger? We handle the details—permits with the City of Culver City Building and Safety Division, HOA coordination in Fox Hills, and inspection scheduling—so you don’t have to. Get the reliability your home office, appliances, and media deserve. Call or text Shaffer Construction, Inc. at (323) 642-8509 or email hello@shaffercon.com to schedule your assessment. Let’s protect your Culver City home from costly surges—quickly, cleanly, and to code.
