Outlet Tester

An outlet tester is a compact device used to verify the safety and wiring of electrical outlets. It plugs into a standard 3-prong receptacle to detect issues such as reversed polarity, missing ground, or faulty connections. Equipped with internal circuitry and light indicators, the tester analyzes voltage and polarity, providing easy-to-read results to confirm proper wiring or highlight potential hazards. Ideal for electricians and DIY users, it ensures outlets are safe to use and helps prevent electrical shock risks by identifying wiring errors.
