It sounds like you are dealing with 3-phase in a delta configuration. What you have to do is contact an electrician knowledgeable in working with such circuits.

I second that. Don't mess with it.

That's some serious electricity. What is feeding it? Can't you run a ground from the source. Why do you need a neutral? Or do you really just need a ground?

What you need to do is pick up the phone and call an electrician!
