Whole-Home Surge Protection
in Los Angeles

Type 1 SPDs are installed at the main service panel and protect against external surges from the utility. Type 2 SPDs are installed at sub-panels or branch panels and protect against both external surges and internal surges from large appliances cycling on and off. For best protection, use both.

No — a basic power strip only protects the few devices plugged into it. A whole-home SPD protects everything connected to your electrical panel: HVAC, refrigerator, EV charger, well pump, pool equipment, security system, and all outlets and hardwired devices.

Not always. We perform a free load calculation to determine if your existing panel can support a new circuit. Many homes can add a single EV charger or appliance without a panel upgrade if they have 200A service and available breaker slots. Older homes with 100A service typically need an upgrade to 200A. Factors include your current electrical load, the new circuit requirements, and local code requirements. We inspect at no cost and let you know before providing a final quote.

Panel-mounted SPDs typically last 5-10 years depending on surge frequency. Most units have a visible indicator light or alarm that tells you when protection is depleted. We install only UL 1449 4th Edition listed devices.

A direct lightning strike requires a dedicated lightning protection system. However, the majority of surge damage comes from nearby strikes, utility grid switching, and internal load cycling — all of which a Type 1 + Type 2 SPD system handles effectively.
