Electrical code requirements in the US
I am from 220v land in Europe and am finding out about code reqs in the US in order to wire a couple of outlets in a shed.
I intend to run 220v out to the shed to power my European tools but also need 110v for my new US toys!
if I run 3 wires to the garage (2 hots and a ground) this is ok for 220v. If I then want 110v do I simply take one 220v leg and use the ground as the neutral? If so, to what do I then connect the ground on the receptacle?
I understand from what I have read that neutral and ground may only be connected at the main panel subsequent to a code change in 1996, so I am confused as to what to do. Do I need to run 4 wires out to the garage and use one as a dedicated neutral?
Thanks for enlightening me as to how things are done here!
