What is a voltage detector?
A voltage detector is an electrical device that detects the presence of voltage. It’s a handy item to have when you’re troubleshooting a failed product or working on a device and want to ensure that it’s safe to work on. Voltage detectors are different from multimeters, as these tackle a variety of measurements and tests, along with the voltage level on the wire, while a voltage detector only detects the presence of voltage. Using a non-contact voltage tester is easy – simply touch the tip of the tester to the wire or outlet faceplate and it will either light up or make a sound if voltage is detected, depending on the brand you have.
When to use voltage detectors
Voltage detectors are useful for a variety of applications, from checking electrical circuits in commercial or industrial buildings to exercising safe working practices. These tools can make identifying a problem wire much easier for a quicker repair, checking power is switched off before handling a plug or spotting breaks in AC power cables in environments where lighting and audio equipment is used. They can even be used to spot a break in a wire of string lights to save you the time of checking each bulb for the problem. Non-contact voltage testers can be used to identify circuits for a quick reference point while 2-pole voltage testers safely isolate a circuit so you can carry out electrical repairs.
