## Questions & Answers

**Q: Can this be used as a single circuit generator transfer switch? If so, how would that be wired based on the terminals of the switch?**
A: Wired so as to be Acting as a Circuit Transfer Switch.  SPDT, single pole double throw.
Position 1 connects Terminals 1 and 2. 
Position 2 connects Terminals 3 and 4.
Center Position has NO contacts closed.   If you hook (jumper Wire) across Terminals 2 and 4 then it is common [ Wire removed from Breaker] connects on here, and is the LOAD, While Terminal 1 is Source - connect wire  to Breaker = Power Company Source...
 and Terminal 3 is alternate Source, = could be your Generator. 
This will get you started.

**Q: What is diameter of knob shaft?
Does the black plastic split so that one side is inside the panel and the other half is outside?**
A: I drilled a 3/8 inch hole for the knob shaft to fit through and it gave me plenty of room for fine-tuning adjustment to make sure that the switch was centered in the box that I mounted it on. The plate does split into two pieces the front half goes on the outside of the box the back half goes on the inside the box. you will have to mark and drill the holes for the four screws which hold to black plastic plates together and sandwich the mounting surface between them.

**Q: Into what does this mount?**
A: I used an electrical box from Home Depot and modified the cover plate to mount it because I could not find anything better.

**Q: Will this work on standard 120V 20A circuit?**
A: It can be used within the rated voltage and current of this product.
