GFCI testers - hot to ground question
I bought a handy GFCI tester the otherday. My son said I wasted my money since he can test the same function with his voltage multitester.
He proceeded to test from hot to ground of a GFCI outlet and it tripped.
Is that the same thing as my GFCI tester or better yet, is that the same thing that happens when someone drops a radio plugged into a GFCI into a bathtub?
