How to wire up a 240VAC receptacle

<< < (13/57) > >>

dmills:
The P9S13A and 14A have double pole breakers for 240V split phase service (Or I assume 208V two legs plus neutral from a 120V three phase supply), see the quickspecs sheet.

The P9S16A has only single pole breakers for 230V service with an earthed neutral, it is NOT suitable for 240V split phase service or 208V two phase plus neutral.

You have the wrong PDUs for your supply, send em back and get the right ones. 

You could use an isolating transformer to produce a (UK parlance warning) "Separately derived supply", which would give you 230V with an earthed neutral but the NEC may have things to say about this.

If I had the wrong one, which would be the correct one to purchase with the same features (same load capacitance, switched, etc.?)   I talked to my European friend and he said it's just a language barrier and I'm supposed to run 120VAC down the L/+ and Neutral.   I've contacted my VAR and I'm supposed to send him a short email with my question so he can pass it along to the HPE techs, and then we decide if we need a conference call to answer my question(s), if the PDU won't work for my situation, or figure out how it's supposed to wired.

I didn't see any split-phased PDUs listed.   Only single-phase, and 3-phase....at least from my crappy recollection.

Thanks!

And if you do that you'll have a 30A or thereabouts breaker protecting wiring not rated for it.

That's the question though, would I?   This is what HPE needs to answer and why we're getting them involved now.   To see if I'm supposed to wire it with 120VAC going down the L/+ pin and down the neutral pin or if I'm just supposed to have 240VAC going down the L/+ pin.   If HPE says L/+ pin, then I can try to find an equivalent, which I don't think I can, I might be able to purchase a smaller unit that produces 240VAC output and daisy chain a few together, or purchase what the one user linked me to to provide the 240VAC for L/+.   So we have a few options it looks like, depending on how HPE responds.   I've sent the email, tomorrow my VAR will forward it along, and he'll call me later in the day to see where we stand.

Yes. Because it has single pole breakers.

Get the P9S13A instead. Have an L6-30 outlet installed.
