I have been searching for information on wiring Self contained receptacles and switches used in mobile homes and can't find anything! I have been overwhelmed lately with circuits not working, arc faults, flickering lights, etc. All due to bad connections on self contained devices where you just push the wires onto the connectors. Usually the problem is with 3 NM wires being fed to the device. Does anybody know how many wires these terminals are listed for? I can't find the answer so please help.
