Whole Home Surge Protection

Every summer, monsoon storms roll across the Las Vegas valley with lightning that can send a voltage spike through power lines and into your home in a fraction of a second. A whole-home surge protector, installed at your electrical panel, stops most of that energy before it reaches your air conditioner, appliances, and electronics. Pacific Electric installs and sizes these devices for homes across Las Vegas and Henderson.

Reasons You Should Install Whole-Home Surge Protection

One surge can ruin expensive equipment, and smaller repeated surges wear out circuit boards over time. Here is why Las Vegas homeowners add panel-level protection.

• Monsoon lightning. Storms from July through September bring lightning that can induce surges on utility lines miles from where it strikes.

• Surges that start inside the house. Air conditioner compressors, pool pumps and other large motors create small spikes every time they cycle, and those spikes add up.

• Hardwired equipment has no plug. Your AC, water heater controls, garage door opener and built-in appliances cannot be plugged into a power strip, so the panel is the only place to protect them.

• Electronics run on sensitive boards. Variable-speed pool pumps, smart thermostats, refrigerators and EV chargers all rely on control boards that are easily damaged by voltage spikes.

Whole-Home Surge Protector Installation

A whole-home surge protector, called a surge protective device or SPD, mounts at or inside your main electrical panel. When voltage spikes above a safe level, the device diverts the excess energy to ground in a few nanoseconds, so the surge never travels down your branch circuits.

Installation starts with an inspection of your panel. Our electrician checks grounding and bonding first, because an SPD can only divert a surge through a sound ground path. A corroded or missing ground connection makes any device far less effective, so we correct it as part of the job.

Next, we select a device rated for your service size and panel type. Most homes get a Type 2 SPD installed on a dedicated breaker inside the panel, with the leads kept as short as possible, since longer leads reduce how well the device clamps a surge. Homes with exposed service equipment or frequent storm exposure may be better served by a Type 1 device on the line side of the main breaker. Current devices include indicator lights that show whether the protection is still working, which the 2023 National Electrical Code calls for.

Code is part of why this matters now. Clark County began enforcing the 2023 National Electrical Code, with the Southern Nevada amendments, in January 2026. Section 230.67 of that code requires surge protection on services supplying dwelling units, including when service equipment is replaced. That means panel upgrades and service changes will typically include an SPD.

We also look at what you are protecting. If your home has a standby generator, an EV charging station or pool and hot tub wiring, the electrician will tell you whether a secondary device at a subpanel adds meaningful protection for that equipment.

Surge Protection With a Panel Upgrade

Adding an SPD during a panel replacement costs less than installing one later, since the electrician is already inside the panel.

Layered Protection for Electronics

A panel SPD handles large surges. Quality plug-in surge protectors at your TV, computer and home office equipment catch the smaller residual spikes that get through, and the two together give the most complete coverage.
