We have over 100 gfcis at my job all hospital grade we test monthly and find at least 15-20 are bad some of them are never used any ideas.

Do you mean the test button fails or it won't reset or do you mean the GFCI trips for no reason? What brand and model are you using?

What brand of GFI device? Make and model number?


OOps sorry Bal I did not see that you asked the same question.
