What we like most about Triplett products is that they deliver as promised.
Designed for use on 110 – 125 VAC receptacles, the Triplett Plug Receptacle tester detects common wiring problems in both standard and ground fault circuit interrupter (GFCI) outlets.
Easy to use: simply plug into receptacle in order to observe the light pattern; then push the yellow button to test operation of ground fault receptacle. “Test in Progress” LED indicator monitors progress.
This product comes with a manufacturer 1 year limited warranty.
