## Questions & Answers

**Q: What are the locations ot the output of the input locations 1 and 2?**
A: The outputs and inputs are located on the mechanical dial.  Use a multimeter to check current path

**Q: I know this is designed and speced for AC, but is there any reason it could not do DC?  Specifically 90V@10A Max (for a DC motor).**
A: A switch is a switch, it doesn't matter if it is ac or dc.  Amperage does count, however, and since this switch is rated for 40 amps your 10a motor should be perfectly ok.

**Q: Will the terminals accept #12 wire?**
A: In my experience, I had no need to use number 12 wire, but my assumption is the way the clamps work that it would hold # 12 wire. You could always put a feral on the end to make it larger if necessary.

**Q: Is it alright to install this box inside a wall? If yes, anything needs to be done before installation?**
A: You can as long as you are not going over the rated amps. I'm assuming you are going to leave the switch on the outside of the wall.
