    30 amp, 120 volt circuit ?
    Does the electrical code allow for a 30 amp, 12 volt circuit with 15 amp outlets?

    Here is the reason I ask. I have a technical resource (computer geek) asking for a 30 amp circuit running 120 volts in order to power up a individual computer devices. Each device would be plugged into its own outlet.

    Questions:
    1) Can such a circuit exist?
    2) Is it safe?
    3) Is there a better way to handle such an electrical load?

    Many thanks.

    Makes such an animal. 30 A input and multiple 120 V outputs.

    Another way to do things like this but with even more power is to mount a sub-panel on a rack. Use a 4 wire 240 V plug and then use as many breakers as you would like to power the rack of equipment. It works well.

    ABSOLUTELY NOT.

    A 30A circuit must have a 30A receptacle if used.

    They are probably calling for a 30A/120v twistlock receptacle to plug in a big UPS or something.

    You could also use 2 15A breakers and this way you don't have everything on one circuit. From there you could use your 15A outlets. Just an idea.
