| thanks. I know that AC is 60Hz. I just asked about polarity because the instructions specifically state that one screw has to get hot wire and the other has to get neutral or damage to equipment may occur. So I just followed hot through the switch loop back to the unit. I actually ended up moving things around because the humidifier water line was over where I was going to put a box. So I ended up running to switch first and from there to the power ventor control unit, making my original question immaterial now.
since there is such little draw on this 15amp circuit, I was going to use it to put outlet in an adjacent crawlspace and an outlet or two in the furnace room (in addition to the outlet on the furnace for the humidifier.) My local jurisdiction does not have anything on this other than what is in NEC 2008. Since I don't have NEC 2008 nor do I know how to fully interpret it, any help would be appreciated. |
