Voltage detectors look and act like simple tools, but they’re extremely important whenever you’re doing a job with (or near) electricity. These tools will tell you whether electrical current is flowing to an outlet, through a wire or through anything else that uses electrical current.
These tools are extremely handy to have with you not just when doing major electrical work, but also whenever you’re potentially near electricity. Whether you’re changing an outlet or working close to wires while doing carpentry, for example, it’s important to know with certainty you’re not in danger of electrical shock or worse.
