Surge protection is a surprisingly expansive topic. There are a lot of different things that are good to know about it, even for average homeowners who are not trying to become electricians. Here are a few examples:
- Power surges and spikes can happen for a variety of reasons. A lot of people assume that lightning storms and blackouts/brownouts are the only reason why power surges and spikes happen. However, faulty equipment or wiring or having other high-powered devices on the same circuit can cause them, too.
- You can get surge protection for your entire home. Most people think of standalone surge protection units, but it’s possible to install surge protection for your entire house. The best kinds require installation by a licensed electrician, so do your research.
- Surge protectors need to be repaired or replaced regularly. Every time a surge protector does its thing, it loses a little bit of its effectiveness and will eventually not protect your appliances at all. Be sure to check your protectors every year or two.
