Is A Whole House Surge Protector Necessary

Aug 3

Lightning and downed power lines can pose electrical dangers from the outside. Did you know that most surges originate inside your home? A surge protector for your entire house is a must, as small power surges can occur multiple times per day. They come from:

  • Faulty wiring: A poor quality or improperly installed wiring can lead to surges in electric current.
  • Major Appliances Large appliances, which cycle on and off throughout the day, are the most likely to cause power surges.
  • Short Circuits/Tripped Breakers: A surge in voltage or trip of a circuit breaker can cause severe damage to the wiring and even the box.

A major electrical event like a 200,000-volt lightning storm can instantly destroy wiring, air conditioners, and refrigerators. However, small daily surges can cause more serious damage over time. Although appliances can continue to work without significant damage, their life expectancy may be reduced. Surges can also be caused by sudden increases in electric demand.

What Does a Surge Protector Do?

The whole-house surge protection system works on the principle of electricity following the path of least resistance. This allows current to flow safely to the ground. It effectively stops current from entering electrical circuitry.

Point of Use vs. Service Entry Surge Protection

Point-of-use surge protectors are designed to prevent electrical surges from damaging individual devices such as computers or home entertainment systems. The surge suppressor plugs into the device. This level of effectiveness can be achieved by a plug-in surge protector UL-rated that absorbs 600 joules and has a clamping force of 400 volts.

A whole-house surge protector is installed at the main electrical panel. It continuously monitors the electricity influx. The system can redirect excess electricity to the ground if there is a surge in power from the grid. The voltage will not enter your home at all. The system is usually equipped with connections for cable TV, internet routers, phone lines, and other circuits.

Whole-house surge protection systems can protect up to 40,000 amps.

Multi-Level Protection

A whole house surge protector cannot handle all power surges. You won't be able to stop all internal surges. It is best to have whole-house surge protection between power lines, the electrical meter, and between breaker box and meter. Also, point-of-use surge protectors are available for all major appliances in your home. Your grounding system must be in good shape and properly installed.

Cost of Whole House Surge Protector

It is worth investing in a surge protection system to protect your entire house. Professional installation is required and it will cost more than a point-of-use device. Large appliances can be costly to replace. A whole house can be paid for in a single surge of power, and it will also prevent fires or other dangerous events.
