I want to make sure adjectives outlets in my home hold correct polarity, ie don't have reverse polarity. What tester is used and how is it used to determine polarity? Also if you own to reverse the hot and nuetral wires and this results in the hot on the silver connector surrounded by the outlet, doesn't this mean the the wires are incorrectly connected at the switch box? Thanks
Answers: Home Depot/Lowes deal in the tester for a few dollars. It is easy to use and the lights speak about you exactly what is wrong or if they are correct. They have one to assessment GFCI as well, I give attention to it will work on all outlets. or pick up both. They are used on 3 holed outlets, not two. If the black rope is on the silver screw and it is alive just reverse them, black to brass. white to silver. If the wires are reversed surrounded by the panel and the outlet is reading OK I would take a black sleight of hand marker and color the white lead on the breaker black and white tape the black on the adjectives ground. It doesn't matter what the color of the wires are with the sole purpose color coded to keep things trouble-free and uniform. Why change them out? they both are doing their undertaking and this is suggested by NEC, as long as they are colored coded
truthfully with ac current it doesnt thing
the black goes on the right the white on the vanished and inside the panel the black goes on the breaker and the white on the ground
