Tapping 120v from 220v

[captaincrab55]

Thanks again for all the replies.
This was never a "do it yourself" project for me. But, I knew the wealth of knowledge on TBN and wanted to get some ideas from the group. I have learned a lot from reading about the problems and solutions that come across this forum. The ones that have really stuck with me are the safety warnings/suggestions that the "pros" who have the experience (sometimes bad) pass on while answering others questions.
It seems that the best course is to run a new circuit from the main to the shed.
Thanks again.

Great decision.....

There is an additional reason for not sending current through the ground. Electrical systems are designed so that no single failure will cause a safety hazard. If you use the ground wire to carry current and it fails then the metal case of a motor or panel can be come electrically hot (voltage is above ground potential). Depending on the unbalance this could kill you or your cows. If you have a separate neutral and ground, either one failing does not cause a hazard.

Back at the panel you do have the neutral and ground tied together, but that panel is also grounded with a wire to a ground rod. No single failure will create a shock hazard.

Before you had grounds, an electric drill case might short to the hot wire and then you would have 120 volts on the thing you are holding. If, on the other hand, the case were grounded then the fuse or circuit breaker would blow.

I hope this helps

Yes that does help, so it's kind of a "failsafe" system.
Thanks it makes more sence now

I always appreciate the wealth of knowledge that is freely shared on TBN... I know I've had my fair share of questions answered and learned a lot from reading answers to questions posed by others...

Thanks Guys!

Not quite fail safe. Two failures of the right kind can shock you. This is very unlikely though.

There you go. Now you are thinking right. Any other method was a jerry rig and not right or to code in most cases. In the long run you will be money ahead and with the middle buster you already have it will be a easy job to run a piece of 12/2 with ground and put a nice GFI outlet and light in your shed.

Just make sure you use underground rated wire and I would run it through conduit for added saftey.
