No, I'm pretty sure he means "across the 2 high legs of a 120/208 3ph
Wye service", and I'd never heard that idea suggested before.  I can see 
why it reduces the amount of copper you need to run, but it seems as if
it would have compensating disadvantages, though I can't think precisely
what they might be at the moment.

Dear Jay,


I really want to move all newly installed internal and customer
racks
over to all 208v power instead of 120v. As far as I can remember, I
can't remember any server/switch/router or any other equipment that
didn't run on 208v AC. (Other than you may need a different cable)
Anyone have any experience where some oddball equipment that
couldn't
do 208v and regret going 208v? We won't have any TDM or SONET
equipment, all Ethernet switches, routers and servers. I have
control
over internal equipment but sometimes customers surprises you.

you mean 240V AC 50HZ and move from 120V 60Hz? (or also 50Hz)

you will need to check each device if it supports 240V, commonly the
specified power ratings are printed at a stricker on the device
itself.

Kind regards,
Ingo Flaschberger
