And I don't like not having anywhere to plug in my power screwdriver's recharger... I suppose I should see if I can find someplace that has a transformer of an appropriate size, or does anyone already have the part number for something that can provide a few hunderd milliamps of 120V from 208? :-) Isn't 208V usually provided as a connection across two phases of a 3
Once upon a time, Joe Greco <jgreco@ns.sol.net> said: phase circuit? In that case, you get 120V by going between one phase and neutral (no transformer required).
Yes, but this doesn't imply that you have access to those other phases. It is easy enough to be delivered 208V single phase service in a data center environment.

Correct. I have a Smart-UPS RT connected across two legs of 3 phase for 208. The unit does not have a neutral, only ground, so it's 3 wires in and 3 out. The output is only 208 L-L with odd voltages on L-G. Since there's no neutral, it can only be used to drive 208 loads or a transformer for 120. ~Seth
