I have recently been helping A pastor of A church, And the space that has been leased is a industrial building being converted for A church setup, but for the power the room has A 3 phase delta wye, can I run A 4th wire and make this applicable for A single phase, or do I have to use A different box And run A single phase wires setup.

What is an electronics tech. and what is a delta wye? Are you an electrician and do you know what you are doing?

Whats the voltage and phase? There is no savings using a single phase panel from a three phase service.
Have you considered getting a qualified electrican to install the box?

If it is 208/120 what is the problem? If it is 480/277 you need a transformer. Get professional help please.

Along with the others recommendations of letting a licensed electrician do this, since this is a leased building for assembly, there are liability issues and laws that need to be considered before doing this work.

I am going to have my friend who is A licensed
electrician to handle this one, and the box is A
3 phase 4 wire 120/208-v wye.
he said he is going to run A different box,
seperate from what is installed already to
comply with code.
