Gosh, bet that makes the Code Enforcement people very angry. This is
why you need to do your own, independent research. Lots of folks have
opinion they are willing to offer as answers on the "net." Of course,
all you had to do was drop by the hardware store, or Lowes, or HD, etc
where you could get a touchy feely answer and see for yourself.



In recent posts I have heard mention of 12/2 and 10/2 wire, as well as
12/3 and 10/3 wire. What is the difference and what would you wire a
new shop with?

I assume the 12/2 and 10/2 mean with ground.? What is the extra wire
in the 12/3 and 10/3 for? Is that for wiring 220V?

10/3 and 12/3 are with ground. Also there are only 3 wires in those cables.

10/2 and 12/2 only have 2 wires.
