Mine was off for a year as I rewired 3 rooms through the attic.Guess I'm 1 of those big time code breakers..lol
I had my cover off probably 3 months while i updated the old wire and ran new wire in our house. I even got 1 step further and use 12/2 with 15amp breakers. 14/2 wire these days is just brittle and breaks when you do a hook bend.
