Setting up a new shop, but will need a 220 line for servicing some high 
power equipment.

This transformer sits on the floor near the breaker panels:

General Electric 9T23B3872

Specs say it steps down 480 to 120 and 208.

Is 208 gonna work for 220? Never heard that voltage mentioned in my travels.

The 120V wall outlets read about 123V on the DMM, sort of high than where I 
was previously.
