NON CONTACT VOLTAGE (NCV) TESTERS are an important personal safety device.

A non-contact voltage tester detects electricity in a wire or outlet, just by being in close proximity to the wire or power outlet.

A non-contact voltage tester is a useful tool for any kind of electrical work—there’s no quicker or simpler way to safely check for electrical current in a wire, outlet or switch.

Always read the manufacturer’s operating and safety instructions and always check the tester on a known voltage source prior to using it
