| Hi guys,
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! Cheers!! |

| Your best bet would be to post your question on the electrical wiring forum. There are some pros there that will help you. |

| Thye safety ground is NEVER used as a current carrying conductor. To get 120/240 V you need FOUR wires, hot,hot, neutral (groundED), and groundING (safety ground). A separate structure can only have a single circuit (though a 120/240 V counts as one circuit) without having a panel. Your 240 V tools will run fine on US 240 V wiring. If they have universal motors (brushes and a commutator) they will even run at the same speed. Induction motor will run slightly faster (US is 60 Hz vs. European 50 Hz). |

| Are not Europe and Asia on 3 phase electricity? So, unless a transformer is used in the system, the life may be reduced for the Euro motors... Just a thought. |

| "Are not Europe and Asia on 3 phase electricity? " No more than we are in the US. 3-phase is used for large loads, either industrial or with a transformer setup in large buildings (208 V 'sitnger' system).
