Whole Home Surge Protection in Phoenix


Your home is filled with expensive electrical appliances and devises that could be damaged in the event of a power surge. Without surge protection, you may be left with the hassle and expense of replacing these items. A whole home surge protector will keep your essential systems and important devises safe. Read on to learn more about surge protection and the solutions Super Electric offers.

What is a power surge?

A power surge is a rise in the electrical current running through your home. The surge usually lasts less than one thousandth of a second, but even in that brief about of time, serious damage can be caused.

Power surges can occur due to a number of causes, including:

  • Lighting
  • Downed power lines
  • Utility equipment problems
  • Faulty wiring in the home
  • Appliances within your home

While most people think of a lightning strike causing a power surge, that is actually fairly rare compared to other causes. More often, devices in the home cause electrical currents to spike. Appliances which use more power, such as air conditioners and refrigerators, can trigger a power surge strong enough to cause damage to the electrical devices throughout your home. This typically happens when the system is switched on, which requires a sudden high demand for electricity.

Not all power surges are strong enough to cause instant damage to your electrical devices. Reoccurring power surges cause damage over time, as equipment is repeatedly subjected to power fluctuations. Appliances and other devices may fail much earlier than their expected service life without surge protection.

What a whole home surge protector does

A whole home surge protector will detect excessive electrical currents in the event of a power surge. The device will absorb increased voltage and divert the electrical current, preventing it from reaching your outlets and the devices that are plugged in. Once voltage levels are detected in the normal range, the whole home surge protector will restore power to the home.

Whole home surge protectors provide protection to the entire electrical system and the devices plugged in throughout your home. They are effective in eliminating power surges caused by both internal and external sources.

Whole home vs. individual surge protectors

A whole home surge protector is connected to your home’s electrical panel, protecting all devices plugged in anywhere inside or outside the home. Whole home surge protectors will offer protection from surges of 40,000 amps, or more depending on the model installed. An individual surge protector only protects the devices plugged into it, and may not have the capacity to protect multiple devices on the strip.

Whole home surge protectors and plug-in surge protectors can be used simultaneously to protect your devices from damage caused by excess current. Plug-in surge protectors are often used by homeowners as a “backup”, especially for expensive electronics of high-power systems like a refrigerator.
