110VAC from 220VAC How to?

Well i AM an electrical contractor, and i believe i also posted on your previous post the simple answer. IT CANNOT be done SAFELY. In a 110 volt circuit a neutral wire HAS to be present to complete the return path on the circuit. this path is not needed in a 220 configuration. You cannot use the ground wire for this path. Even though you will get a 110 reading with a meter between the hot leg and the ground wire, your then placing an electrical current on the fault path (ground)wires...and this can NEVER be done. you will have destroyed the fault path and the safety of this system.

I even checked with my supply house to see if theres a small step down transformer that would work...and they told me ... NOPE.

So then if the pump house was fed with a suitable 4 wire cable a 110 Volt feed would be possible?

Transformers are available to go from 240VAC to 120VAC, however since you only need it for a "few days", I would buy a generator for the cost of the transformer. What's the distance from power panel to the well, and well to the pig pen? If you can live without the well while you work, you could also temporarily disconnect the pump for awhile, connect the pump line to 120V breaker at the panel, and then connect the line to the pig pen.

Hi
If you're not an Electrician you should not give Electrical advice period.

I guess this theory largely eliminates the purpose and therefore the use of this site altogether.

I should close my account.

Yes, it would be possible.

If you were going to do that, you'd be better off running individual circuits to both devices.

I thought it was a tractor site, Tractorbynet I suppose you think it would be ok to give medical advice or maybe legal advice also. I would feel bad if i were to give advice to someone on how how to do something and they were killed as a result of my advice.

TractorByNet also has a rural living forum and free advice, especially from the Internet should never be considered as gospel.

When you think about it... how can you be sure of any one's background and qualifications on an anonymous forum?

As to advice... I have often shared my experience as a State Certified Arbitrator, never claiming to be a lawyer because I am not...

I also work in a Hospital... Doctors and Med Staff often come to me for advice/help and I have no training as a Doctor... only as an engineer working in bio-med.

You don't need to be an electrician to see that what he wants to do is a bad idea.

Come to think of it, I doubt there are any automotive engineers on this forum. We probably shouldn't be trading advice on tractor repair, either.

I asked to see if I was wrong since I've thought from the git go that I would need four wires to get 110VA from a 220VAC circuit.

the proper way?

A sub panel has to be installed at the pump houseing. THe sub pannel is fed with the 220v line from the house. The sub panel must have a main breaker less than or equal to the breaker it was wired off of in the main panel. The new sub panel must be grounded with its own ground rod. The new sub panel contains a 220v breaker for the pump and a 110v breaker for the other line.

If any of the above doesnt make sense, hire it out. :thumbsup:

Schmism, I'd really like to know why you think this?

All of this makes sense except the part about "The sub panel must have a main breaker less than or equal to the breaker it was wired off of in the main panel."

Why the only function of the main breaker at the subpanel is to serve as a On/Off switch since the circuit feeding the subpanel is protected by the breaker in main panel that feeds that circuit.
