The Ideal 61 501 receptacle tester tests GFCI receptacles for proper operations as well as warning against faulty wiring in 3 wire receptacles. The tester is used on 125V AC circuits. Ideal Industries was started in 1916 by J. Walter Becker. His belief that every product should be worth more than the price paid for it has been the core IDEAL business principle for over 90 years. Today, the many loyal distributors and customers that make IDEAL successful are a testament to Becker s original philosophy.
