That last bit is important when you're looking for stuff so you don't find something like you already have that's intended for Europe.

See, I see things like 208V NA/JP with an L6-30P .   That's gotta be a typo.   It's single-phase.   That must be a 240VAC North American one.   But load capacity is only 5KVA.   We're already over that.   I don't remember what it was tallied up to, but I can find it real quick.   Without the BGA rework station (4800 watts), we're at 12,319 watts total, assuming everything's on at once, which it would never be.    So we could subtract some of that and we estimated around 6,360 watts.

Bratster:
208v single phase is a valid voltage in the US. In a commercial environment with a 3-phase Supply that is what you would get Line to Line.

But since it is not using all three lines, it is not a three-phase device.

 Therefore it is a single phase device.

Yes, it's single-phase.   So is it a typo?   I know 208VAC is a valid option in the US, but I thought that was only for three-phase, not single-phase.

I wish we could do the Intelligent PDUs, but they don't offer something we need.   Which really sucks, and leaves us back with the switched, metered, or switched and metered.   The only things I can find for Switched and Metered are horizontal, and the only one I see provides less than 5KVA capacity....

IanB:
It looks like the P9S15A is the only single phase option for switched and metered, and it is vertical mounting. It also only says on the specifications "200-208 V input". It doesn't say "200-240 V input". I do not know if 240 V would be a problem for it. HPE technical consultants would have to tell you the answer to that. If you talk to a salesperson they are likely to cover their ass and say "no"...

Bratster:
You're only going to get 208 volts with a 3-phase Supply coming into the building.

But just because you have three phase doesn't mean every single device you have has to be three phase.

If something is only using two lines, and NOT all 3, then it is not called a three-phase device, it would be a single phase device.


Yes I know it's weird that even though there are two lines and if there was a third it would be called 3-phase so you would think it would be called two-phase, but no.
