What happens if I hook up a GFCI wrong?

What happens if I hook a GFIC wrong? For instance..line side on the load side and load side on the line side? Would I be able to read voltage with a meter? Will the GFIC be ruined?

Welcome to the forums! Hooking it up incorrectly will not give you any protection. That is why there is yellow tape on the load side when you install it. Hook the line side to the incoming line, and any downline receptacles to the load side.

But by hooking it up backwards will not ruin the GFIC? Just no protection. Did I read this correctly? I can not get voltage reading at all and thought that is what I may have done and the GFIC is not bad. It will not test.

Let me add this info here with alot of new GFCI they do have lock out feature if you miswired the GFCI device it will not funtion they designed like that so if you get line and load reversed it will not fuction or one of the line or load conductors switched around it will sense the same thing.

Typcially most new GFCI design with line and load reversed they will simply not reset or enable to run.

Merci,Marc

Hook it back up right and see if you get a reading. If not, and it is an older GFCI, you may have scorched it. I doubt it.
