A power surge is a sudden increase in voltage that has the potential to damage or destroy electronic equipment in a home, commercial building, or industrial and manufacturing facilities.
Surges can occur when large appliances, such as air conditioners, turn on and off, from electric utilities or lightning. Surges can reach tens of thousands of volts. It is crucial to keep your valuable electronics safe by protecting them from surges that can damage or destroy them.
There are 2 levels of Surge Protection:
- Point-of-Use Surge Protection- This is easy to use by just plugging your electronic. However, it only protects electronics plugged into the device and requires to be replaced over time or after a major surge event.
- Whole Home Surge Protection - this is the best form of surge protection, as it gives protection for your entire electrical system at home including light switches, outlets and large appliances. It protects against bigger surges and provides surge protection for longer as compared to point-of-use devices. This must be installed by a qualified electrician only.
Some important points to keep in mind: No surge protection can protect against a direct lightning strike. Hence, during storms it is best to disconnect sensitive electronics .
Power strips and surge protectors are not the same. Not all power strips offer surge protection.
