## Questions & Answers

**Q: I plan to connect the generator output and the power company mains using this manual ts. where do i connect the 'earth' wire?**
A: The grounds are common, so the grounds can be connected together. The neutral needs to be switched through the switch.

**Q: can this take 16 mm cable in the terminals ?**
A: 16mm or 16 gauge?  It can take up to 14 gauge MAX.  I tried 12 gauge stranded and it wouldn't fit

**Q: How would i wire this to act as a spdt switch on 12v dc? i wish to switch between two power sources. any advice is appreciated.**
A: You would have to connect a jumper on the output side. (eg. sw to pos 1 will connect pole 1 and 3.  sw to pos 2 will connect pole 2 and 4. pwr source 1 to pole 1 and pwr source 2 to pole 2. add jumper btwn pole 3 and 4 and use pole 4 as an output.)  NOTE!! Check pole switching this is just an example!!!  also be aware of the amperage this is an AC switch box.

**Q: I need to switch between two ac sources, do i use 1/3/5/7 as the output? i follow that 2/6 for pos1 and 4/8 for pos2 , but what output terminals?**
A: Connect the load's hot wire to positions 1&3.
Connect the load's neutral wire to positions 5&7.
Connect AC Source #1's hot wire to 2.
Connect AC Source #1's neutral wire to 6.
Connect AC Source #2's hot wire to 4.
Connect AC Source #2's neutral wire to 8.
