I have a couple of in wall heater/fan units that were originally wired to run at 120V/15A. They are Cadet Register Plus Mulitwatt units, so they can also run at 240V. After doing some reading, I thought that it might be better to have them run on 240V, so I was thinking of rewiring them.
In my reading, as I understand, the only thing I would need to do, I THINK, is to change the neutral in the circuit to a hot breaker, and leave the ground the same. The wiring instructions on the device does not state any differences in wiring, so I am assuming that the device handles either voltage the same. Also, right now I have the hot (black) passing through the thermostat (separate). Would I need to change this? I would think it would work the same (it is rated for 240V-not that it will be sensing anything different-would it?).
Also, would it just be two bridged 15A breakers?
thx
