I have been trying to figure out how to wire a remote switch to my Nova 1624 and in the process I shorted out the magnetic switch and it is completely toasted :eek:. The switch is a double pole switch so there are 4 contacts 2 for the hots and the 2 neutrals. I figured I would just get another DPST switch with the correct ratings and I would be back in business. Every DPST switch that is not a magnetic switch has the 4 contact but the one I fried has an additional contact :confused:. The wiring diagram on the side of that switch has it labeled as being connected to A1, which goes down into the motor and you can't see what its connected to. From what Ive been told this A1 goes to a thermostat tied into the run windings of the motor and the other end goes to the coil on the mag switch. This makes sence to me because I took the mag switch apart and verified that it does go to the coil in the switch :rolleyes:. So if the thermostat on the run winding get to hot it opens the circuit which cuts power to the coil in the switch and in turn shuts down the motor untill everything cools off. I installed a regular DPST switch and left A1 from the motor disconnected and everything work just as it always has. After I saw that all appeared to be good I made a remote switch, hooke it up averything works just like I wanted it to. So here are a my questions.
1. Is my understanding of the thermostat and magnet switch correct?
2. Do motors in general have some standard as far as labels on a wiring diagram ? I would really like to know for sure what A1 is.
3. I like the regular DPST switch better than the magnetic switch because it doesnt revert to the off position when using the second switch. Besides not having any thermal protection, are there any other risks in leaving A1 disconnected?
Any facts, thoughts, opinions or wise cracks would be greatly appreciated.
