Surge Protection Buying Guide

This web page provides a buyers guide to domestic electrical surge protection

 

Why Is Surge Protection Important?

Surge protection is important because a surge protector prevents damage to electrical applianceswhen the electrical power in a circuit increases – a power surge.

 

The electrical voltage or current, or both, can increase for many different reasons, for instance a nearby lightning strike. Electrical appliances are not designed to withstand the rapid increase in electrical energy (power surge) so can be damaged.

What To Look For When Buying A Surge Protector

A very good indicator of the quality of a surge protector is the price – you get what you pay for.

    • The operating voltage – will the surge protector operate at the required voltage?
      • The normal mains voltage in the UK is 240 volts.

 

    • The ‘let through’ or ‘clamping’ voltage. The voltage above which the surge protector operates.
      • You need a surge protector with a let through voltage of less than what will damage your electrical appliances.

 

    • Power rating – will the surge protector withstand the possible increases in electrical energy.

 

    • Response time – how long after the electrical surge begins will the surge operate.

 

    • The number of outlets – the number of electrical appliances that can be plugged into the surge protector.

 

  • Indicator light – does the surge protector have a light to show it is working?
