Receptacle & GFCI Testers & Analyzers

26 products

Receptacle and ground-fault circuit interrupters (GFCI) plug into outlets and use colored lights to reveal problems that may result in shock and electrical fires. Receptacle tension testers plug into outlets and measure the spring tension of the receptacle to ensure the outlet has sufficient tension to keep equipment plugged in and secure. Accessories pair with compatible testers to expand use and improve performance.
