Socket testers are portable, handheld electrical test equipment designed to check the functionality and safety of electrical sockets or outlets in various settings. Using a socket tester verifies whether the electrical sockets are working correctly or wired properly, preventing electrical accidents, fire hazards, and appliance damage. Depending on the tester type, they can identify various issues, including wiring faults, improper grounding, open circuits, earth/ground issues, reverse polarity, GFCI and AFCI testing, and overload circuits, among others. Socket testers feature built-in circuitry to detect and analyse the electrical wiring in sockets and use LEDs or digital displays to indicate the sockets’ status. Additionally, outlet testers are a user-friendly interface widely used in residential, commercial, and industrial settings.
