Mr/Mrs Customer:

I disagree with the other "expert".

To get 120V circuits from an existing 480V supply, a step-down transformer is required.

If you will give me some more info, I can determine the size of the transformer...

What size 120V circuits do you need?

What size wire is at the 480V disconnect or what size breaker feeds the disconnect?

Let me know and we can continue.

Thank you
