Whole Home Surge Protectors in NJ

A whole home surge protector (Type 2 SPD) is a device installed at your main service panel to defend against transient voltage spikes. Surges originate externally, from lightning strikes or utility switching, and internally, when motor-driven appliances cycle on. Positioned at the service entrance, the SPD continuously monitors incoming voltage and, upon detecting a spike above its clamping threshold (commonly around 600 V for 120 VAC systems), instantly diverts excess current into the grounding wire.

Unlike plug-in power strips, a whole house power surge protector delivers centralized surge protection for every circuit. It works in tandem with your circuit breaker: while breakers trip on sustained overcurrent, SPDs clamp fast, microsecond-level spikes, preventing nuisance trips and preserving electronics. Many SPDs feature visual status indicators or alarms to signal when the internal module needs replacement after a significant surge.

For the ultimate home surge protection, consider combining a panel-mounted SPD with Type 3 local protectors at high-value equipment points, ensuring maximum defense for servers, home theaters, and smart-home devices.

Surge protectors are capable of keeping all devices safe against power surges.

The most important appliances you want to use with a surge protector are:

• Televisions
• Computers
• Laptops
• Gaming systems
• Charging phones
• Entertainment centers

It's best to use surge protectors on high-end electronic devices that are expensive or difficult to replace. It necessary to use a surge protector on a light bulb because the worst thing that could happen during a power surge is that it would burn out. With high-end electronics, power surges can cause extensive damage or even destroy these appliances completely.
