Re: Need help wiring up 240VAC.

It'll be 240VAC in reference to L1 and L2 so the load will be the same on L1 and L2.

Re: Need help wiring up 240VAC.

If they cannot accept the return because I installed it, it might be worth it to open up the PDU and try to install the double pole breakers. I don't know how easy that will be

Re: Need help wiring up 240VAC.

"I wired one of the 1400 watt PSUs up to one of my NEMA L6-30P's and plugged it in. Fired right up." I am NOT surprised that it works, the PSU is connected to L1 and L2, the center tab of you house wiring is not being used for your 240V load so as far as the power supply (or any 240V Loads) is concerned it is seeing incoming 240V and that is all it cares, but since you are using L1 AND L2 from your panel then you need dual breakers so if one of the L1 or L2 is shorted to GND it will pop both breakers (they are mechanical linked).
That PDU you have should have been equipped with dual breakers to begin with but they are able to get away with it by specified the incoming as 1-phase only.
All the products I designed for export (TuV is compliance tester) are spec in with dual breaker, and double pole switch due to the fact that some products have harmonized Schuko plug/receptacle which can be connected in either directions.

Yes, I think the problem was I was too technical when asking their supposed tech support the questions. I think they heard split phase, didn't know what I was talking about or just references the datasheet and said no. The only way it might matter is if I had the psu hooked to an "intelligent" PDU. For each PSU, there's not just three prongs for input, but also four PCB pads that communicate with intelligent PDUs that HPE sell. I like the PDU and like the idea of just wiring the European connector to my double pole breaker, but the internal breakers inside, as you mentioned are single pole, which is why we need the one phase 240VAC. How hard do you think it'd be able to source the double pole breakers and install them, if it's even possible. Granted, warranty would be over with I'd imagine, but would that be doable do you think? I can't crack it open to take a look unless they say I cannot send it back...but if it's as easy as just buying the proper breakers and soldering them in or wiring them up, I think I might rather do that.

What do you mean the distribution panel? My breaker panel? Yes, that should trip, but might not. The internal ones are 16 Amp each (derated, so essentially the 20 amp). Its a 7.3KVA PDU. I think we determined we needed double pole to 30 AMP breaker, maybe 40

Re: Need help wiring up 240VAC.

Can I see good clear pictures of your PDU? I like to see what the two 16A breakers look like from outside.

Yes sir. I will show you them tripped and not tripped. It's a type of rocker switch, but is flush (doesn't look like a rocker) until you trip it. I will go take the pictures now for you.

Re: Need help wiring up 240VAC.

These three pictures of are the L1 top row (for the back of the PDU, there's two rows, a top row called L1, a bottom row called L2). There's two breakers, one called L1, one called L2. This is just one of the two breakers.

Keep in mind, the value shown is derated, so the American two-pole version should show 20-amp, not 16-amp.

I can provide measurements with my caliper as well, if need be. There's two screws / bolts per breaker. I was looking at E-T-A and although they have one that's close, because it doesn't have the screw holes, I think we can rule E-T-A out as a manufacturer.

Re: Need help wiring up 240VAC.

Hrmm, for some reason, they're sideways. That's not the way I took them. Sorry about that.

Re: Need help wiring up 240VAC.

"Keep in mind, the value shown is derated, so the American two-pole version should show 20-amp, not 16-amp." That is correct for those IEC outlets, the large (IEC-320-C19) one is rated 20A US, 16A Euro, the smaller (IEC-320-C13) 15a us RATED, 10A Euro rated.
Hmm, I cannot tell if they are magnetic or thermal breakers type.
The breaker itself rating is real 16A. I spec in 16A for the products with IEC-320-C19.
I use Carling in most the products since they can custom made for us in our application.

Holy cow! How did you find them so quickly?? You are amazing! Are you saying I'm correct in the sense that the double-pole ones I'd want would say 20A and not 16A on them?

How could I tell if they're magnetic or thermal? Would there be any tests I can perform without opening them to test?

Finally, do you think it very well might be possible to just switch out the 16A single poles for the correct double-poles? Which worries me is they don't make this 7.3KVA PDU for North America. They make ones half the size, but not this large. I wonder if I'm missing something more than just the breakers and receptacle....I purchased the double pole 40-amp breakers, but I might need 50-amp double-pole (for the mains panel).

The 7.3KVA appears that it might be derated as well, and that the PDU, according to one of the documents I found, supports up to 10KVA. With a power factor of .99, we're looking at ~42 amps (10,000 / 240). Not that I'd necessarily be having a power factor of .99, I just want to make sure I'm safe and don't do anything wrong here. Because their plug is showing a derated value of 32A, I think 40 amp is just right. What do you think?

Re: Need help wiring up 240VAC.

Pure Thermal breaker will require derating based on ambient temperature, the higher the Ambient the less current it can handle. I doubt that HP will put in pure thermal breakers, they are thermal-magnetic has better derating than the pure thermal breaker.
You want 16A, not 20A on that PDU to maintain the same protection.
There is also more thing to consider for the replacement breakers, more likely to be made for high in-rush type, not fast tripping, the only way to find out is to look at the label on the existing breaker.

Your house panel breaker: you should consult your electrician and NEC rules.
It is not that simpe.

Re: Need help wiring up 240VAC.

I'll read the articles first thing tomorrow morning, i'm going to bed. For me to read in the AM though, if I have the chance to send the PDU back and purchase a couple of the American versions (that provide less KVA per PDU), would you recommend I do that over modifying the existing one?

I'll go over the NEC rules a bit more, you can grab them for free off the government's website (or maybe it's a .org one?), I can provide the address if you want it.

Throwing in the double pole breaker in my pain, replacing the internal signal pole breakers with double pole breakers, and then wiring up the receptacle Stj linked to isn't all there is to modifying this PDU? Lot more to it? I was afraid of that.

If those pictures are the true pictures for the series, it's definitely not J series. With the button, it's not flat. It's more like this --_ if that makes any sense. I'm trying to explain the best I can in words. Right after the number 16, there's a small slope where it goes down to the OFF level.

To try and be a bit more clear on this, we'll look at the bottom as having two levels, the ON level, which if the breaker was removed, and sitting straight up, the ON level is physically higher than the OFF level. Only by a couple mm's.

The picture for the B and J series, neither of them appear to have the slop that I'm talking about. ON is level, then slopes down real quick like to the OFF label, which is level, but not at the same height as the ON level. It's recessed.

Re: Need help wiring up 240VAC.

You need to conform to your local code your local code beside the NEC. I do have have lots of NEC info at works for reference, there are tons of info but it still comes down to local codes.\
BTW, did you get the user manual/wiring instruction, etc with that PDU?
What compliance agency does it have on it?

[stj]

Re: Need help wiring up 240VAC.

if you fit a double-pole 240v 32A RCD between the double breaker and the IEC socket, it solves the electrical problem
not sure about this "code" crap though.

in short, an RCD monitors the current on the 2 wires - if one is higher it assumes a problem and trips.
if a single-pole breaker on the pdu trips, the rcd should trip.

infact if your concerned about kids in the basement, an rcd on it is a good idea anyway.
it will trip if it see's a difference of 30ma - that's good enough to save someone who touches a live terminal.

There was no user manual / wiring instructions. Just some stupid pamphlet that seems to come with all of them. This one is a little different and says Important PDU User Documentation Download information

To download the latest user documentation, see the Hewlett Packard Enterprise website ( http://www.hpe.com/support/mPDU_manuals ).

For important safety, environmental, and regulatory information, see Safety and Compliance Information for Server, Storage, Power, Networking, And Rack Products, available at the Hewlett Packard Enterprise website ( http://www.hpe.com/support/Safety-Co...rpriseProducts ).

There's another generic pamphlet as well but just talks about HPE servers, racks, etc. Could you give an example of what the Compliance Agency would look like? Maybe it's on the PDU or the plug itself?

I contacted my Account Executive to see if I could return it. Sorry for the long delay in responding. I've been working on a long contract project with someone for the last couple years that I think I just finished (yay!!!!) and he had to come over and double check the code before taking it to his company and putting it into the test phase.
