I'm helping my brother repair a mobile home and it is wired with self-contained switches/receptacles (14-2). In several areas we had to replace the sheet rock and thus installed new-construction gang boxes for the switches/receptacles. I'm fairly confident with regard to rewiring the receptacles but am not sure about the switches. By the front door there are 3 separate self-contained switches. Each of the three switches has 3 romex wires that terminate in the self-contained device. Each switch was wired exactly the same (per each switch - all ground wires laid on each other in the ground terminal, all white wires laid on each other across both neutral terminals and finally, all 3 black wires were laid on each other across both hot terminals but all 3 black wires had a section removed between the 2 hot terminals (per switch - none of the 3 black wires were continuous across both hot terminals). There is no 14-3 wire in any of these 3 switches. There is no power connected to this mobile home. All of our worked is being performed via portable generator. 1. How would I wire each of these self-contained switches to normal switches? 2. Are these all single pole switches? 3. Are these self-contained devices safe and reliable? 4. If it were you, would you replace all self-contained devices in this mobile home? Thanks very much in advance! Keith.
