Yeah, but that's L-G voltage (geez, did you even look at the picture?) And Seth just finished telling us that it was 211 L-L: Seth > "The L-L voltage on that same PDU is 211." What's going to be presented at the neutral and hot of the 5-15R of the monitor power adapter are the L and L. Think about it.

Yes, Seth just finished telling us that in the portion of his message you conveniently snipped. > I'm going to suspect either > your fairly out of balance, or you've got a good bit of voltage drop by > the time it arrives.... > > But since the concensus from those who haven't used this is that the > device will present 208/240 at the 5-15 plug, I withdraw my suggestion and > leave you to your own methods. (for the rest, test it yourself) For those of us who *have* used this, we're telling you that it'll present 208/240 at the 5-15R. > I also won't argue using ground for neutral, that's like arguing bonded vs > unbonded panels. No it's not. Only idiots argue for using ground for neutral. In doubt? Ask your electrical inspector. ...
