Maximum bins are tapped for a #10-32 screw for a floor screw due to the fact as a count number of conference and enterprise practice, that's what anybody makes use of. I consider the minimal screw size is #6, however -32 is the coarsest allowed thread pitch. That is because ul standardizes container thicknesses, and this assures enough thread engagement to be powerful. -Forty is also allowed. A sheet metal screw is out of the question. A self-tapper is ok if it's far -32 or finer.
I'm installing a smart mild switch right into a field with out a floor cord, screw, or threaded hole for a screw. The transfer field itself it steel and grounded (stay twine to box was 120v on my multimeter).
Are also there switches in which the twine is a part of the switch. I loosened the screws but the cord wouldn’t pop out. I’m assuming it’s connected to the transfer itself and i’ll want to reduce the wire. This means that you should connect the ground screw on the transfer to a ten-32 system screw threaded into one of the holes within the back of the container the usage of a naked or inexperienced #14 twine pigtail. Your average big-container shop will carry pre-made-up floor pigtails that you may just screw into the returned of the field then connect to the ground screw at the transfer, or you may make your very own with a 10-32 gadget screw and a duration of 14awg twine that is been shucked of its insulation by looping one end of the cord around the screw.
