What are Surge Protectors?

A surge protector is a device that detects and prevents transient overvoltage from damaging electronic equipment. These units are equipped with specialized circuits that divert power surges to the ground without reaching connected electrical appliances.

Surge protectors are also called surge suppressors, spike suppressors, transient voltage surge protectors, or SPDs. These units protect devices like fridges from power surges or spikes.

Power surges and spikes are increases in voltage beyond acceptable levels. A power surge lasts for more than three nanoseconds, whereas a power spike lasts for two nanoseconds or lower.

What Is the First Thing to Do in an Electrical Emergency?

In an electrical emergency, the first thing to do is turn off the main supply’s power. Cutting the power supply will help reduce the risk of electrocution as you contemplate the next move. It also helps prevent sparks, fires, and the possibility of the electric issue spreading to other sections.

This emergency response is only effective if you know where the main power supply is located. Flip the switch once you find the breaker box.

Cutting off the power supply at the source is only recommended if it is safe. Don’t attempt to switch off the power if the main supply is affected or poses an electrocution threat. Contact an emergency electrician if you’re unable to switch off the power supply.
