    Metered/switched 30A 120V PDU without multiple banks of 20A circuits?

    Is anyone aware of a metered or switched PDU that has everything on a single 30A 120V circuit, instead of the 2x 20A circuits that most of them come with?

    I don't think that would meet UL since the output receptacles are not rated for 30A... So I doubt it exists.

    I'd recommend diving into a 20a / 208v circuit+PDU.

    Something like AP7932?

    The AP7932 has two 20 amp breakers, one for each bank of outlets.

    So you want 15 or 20a breakers per port? Seems excessive. Move to 208-240v the power supplies are more efficient and having enough amps is a lot easier. Something like a AP8659EU3 208v 16 amps should be about the same costs as a 30a 120 circuit.

    No.

    For example, the AP7932 (a 30A 120V PDU) has two banks of 12 power plugs, each on a 20A breaker. Other 30A 120V PDUs that we've seen are setup the same way.

    We were hoping to find one that had a single 30A breaker for all of the plugs, rather than two 20A breakers with two separate banks.

    208V is not readily available for this application.

    Its not possible exactly due to what was said by Xeon852. It's a fire code breaking liability so no one will make one.
    You MIGHT find something done (or custom order) by european companies with C13/C14 sockets but for 120V (although standard power @ Europe is 240V), then the sockets would be properly designed for 30A and thus would be able to suck all the power without melting down, and then would be certifiable/underwritable.

    Ok. Thanks.

    That would not meet code you would need to have plugs rated at 30a. C13 and c19 are 10a and 16a respectively. The only way to get what you want would be breakers per plug or using an uncommon plug like the nema 5-30r.

    C13 and C19 are 10A/16A @ 230V (2300W and 3680W respectively). Having a 30A@120V would be 3600W.
    But yeah, 5-30r would be safer to find in the US.

    30A is a lot for a 120V circuit.

    Speaking from experience, switch to 208V and get 30A PDUs that way. Tripplite and APC make a bunch of them, and they're pretty well priced.

    Some models have SNMP to allow you to chart & alert of loads too.

    The IEC connectors are odd ducks in that they are rated for up to 250v per IEC-60320. Pretty much the intent is to make a set of standard plugs/receptacles to go from whatever the local standard is to the IEC connector so that gear need not care what the local standard is aside from the odd 120/240v switch.

    To describe them in watts is a bit disingenuous as that capacity changes dependent on local voltage. Amperage is limited independent of the voltage as that is mainly related to wire size. So while the connector and cable may be capable of supplying that many watts not at the stated voltage. As the OP states 208v or similar is not an option that means you need two or more banks with c13/c19 connectors to use 30a.

    As others have mentioned it's beyond the rating of the outputs so considered unsafe.

    Why do you want it?

    If your colo provider is giving you a 30A circuit then some kind of 30A to 2 x 16/20amp splitters and use the off the shelf APC stuff others have suggested.

    Normally more breakers = more redundancy (a fault will trip less and thus turn off less devices) you have a higher fault current availability
