I find junction boxes are really rubbish these days with their steel terminals and badly fitting screws,I stripped two just this morning.I also find that no matter how tight I make the terminals with solid conductors if I go back in a few months to do an addition they are never all that tight.I find the screws easily get cross threaded and strip or just strip anyway or there is a crunch as the terminal breaks loose.I don't recall having this problem when all cables were stranded and the terminals were of real brass.Anyone else have this problem?
