So, I have a us stove 2000 stove. I bought a sensor off eBay. Here's the link. http://item.mobileweb.ebay.com/viewitem?itemId=190638618838 The way it says to install it, it says to put it in line with the black hot wire. I have it inline with the black hot ac wire. I'm attaching a pic. There are two things that make me nervous with the install. One, if a kid reaches behind the stove and touches the switch, they'll probably get electrocuted. Two, I had to drill a hole through the side of the blower casing. I ran the wires through that hole. I'm thinking over time the heat and vibbrations are going to cause the wire to wear thin and then short against the wood stove. I wrapped the wire that goes through the hole with electrical tape to help insulate it more. Wonder what people's thoughts are on this too. I guess I'm thinking about how I'd wire a DC switch vs an AC switch. On a DC circuit with something similar, I'd do it the safe way and switch the ground wire so if something shorted, it wouldn't electrocute someone. I'm just getting into AC electrical in the last year or so. I ran electric to my barn. I wired a sub panel. I've slowly been adding more circuits, outlets, etc. I know from wiring that the right way to switch an AC circuit is to switch the hot wire. I don't know even if switching the neutral wire would do anything seeing in a one panel house, it is perfectly acceptable by code to have the neutral and ground wires bonded. So, if I'm switching the neutral wire with the heat sensor but the neutral and ground wires in the motor are bonded or contact eachother, the switch wouldn't do anything, and that's maybe why the instructions say to switch the hot wire. But I don't know even if the heat switch works yet. It's been about 80 in our house all day today and I haven't lit the fire since morning. It's too hot to get it going to just see if the switch works. I'm sure the temp will drop in the next few days or so. Attached a pic.
