A non-contact voltage test provides an easy and safe way of ensuring that electrical conductors do not have power without having to touch them.

The tester works by detecting the electric fields associated with AC voltages. These fields are usually present near the live conductors, hence the reason why there is no requirement for direct contact with the conductors.

The tester can be used by professional as well as consumers who can use the gadget around the house.
