A surge suppressor or guard is a device used to prevent damage to electronic equipment from voltage spikes called transients. A surge suppressor prevents the peak AC voltage from going over a certain threshold such as plus or minus 200 volts. They attempt to control the voltage complete to a device by either locking or shorting to ground voltage over the threshold. Normal American voltage for home & office building is 120 volts and anything over this is considered transient and can damage electronic devices. A surge suppressor works by having a fuse burn out or a circuit breaker trip when excessive power is being inspired by a device. These surges can be caused by the device itself and from external surges that last long enough.

Electrical surge can damage pc equipment by burning its wires and slowly wear down the device’s internal components. Surge protector can also guard telephone and cable lines since they take electric current as well. Some type of surge protector are basically just addition cords with minimal built in guard so be careful when you are import one. When it comes to surge protectors, you get what you pay for.

Surge guard devices can prevent the reparation from most power surges. There are two types of surge guard you can use for your home or office:

Service entrance surge protection

This is a device which is mount at or near the incoming electrical service. Using service entry surge guard provide protection for the entire electrical system. Some are installing outside at the base of the electric power meter, some are installed inside the main circuit breaker panel and some are install at, but outside, the main circuit breaker panel. These will most likely have to be installing by an electrician or the electric company.

Point of use surge protection

These plans are used with the electrical device being sheltered and are the type of surge protector that are plug into the wall. You should only buy surge suppressors that have been tested to UL 1449, 2nd version and have TVSSs with a listed clamp voltage of 330 volts (the lower the better).

not expensive surge protector

Superior class surge suppressor

If likely you should use both for the minimum amount of guard against electrical spikes.

If you don’t like to have those bulky surge protector lying around then you can invest in surge guard electrical outlets. These are unique electrical outlets that contain surge protection built in and are practical for strategy such as a countertop microwave oven

What to look for in a surge suppressor/protector:

• Adequate links for you to plug in all of your electrical devices An on/off switch will let you to shut off power to every device
• A UL-1449 rating
• An display light or alarm to let you know when a surge has occur
• A clamping energy of 330 (lower is better)
• A joule mark of at least 400. This is a measure of the ability to absorb surges
• A response time of 10 nanoseconds or less
• Guard between all three wire combinations: L-G, N-G, L-N
• A warranty against break to any connected devices
• Filter for line noise
