wiring to an out building (shop)

Posted by carolyn on September 20, 2006, 6:06 am

I am thinking of setting up a shop in an outbuilding, and want to put a
panel in the outbuilding. Currently there is a single line running a
couple of outlets and a light in the building. For the shop, I want a 240v
for my table saw, and then 120v outlets for the drill press, and assorted
other tools, radiant heater, and dust collection system. I will be
replacing the house's 100amp panel with a 200amp, and will reinstall the
100amp in the out building. What gauge wire do I need to run between the
two panels? I will be putting it in a trench with a metal conduit. I am
guessing that a 2' deep conduit should be sufficient. Does that sound
about right?

Thanks, Carolyn

It's been years since I did this, and my memory is going fast, but it seems
I was told NOT to put the line in conduit but to use UF line instead. I'm
pretty sure we just used some 12 gage.

Been retired too long to remember the gage size for 100A but #12
is only 20A.

I have my 200A coming from the pole to the house in 2" and though
I would want the 100A spur line to the shop in UF it needs to be
in pipe too. I would use 2" and lay 2 more 1" pipes beside it for
the future things that I know you will want later like phone,
intercom etc. (Three wire or 3 single wires, either. Some want a
bond wire also back to the main panel. I would.)

Thanks for the information. I do plan to run phone and ethernet to the
shop. Should the phone and ethernet be in their own conduit, or can they
share?

Thanks,

Carolyn

As I said, lay seperate conduit. I wouldn't have anything but
plastic.
