    Or do you want to reduce the quantity of circuits to feed cubicle wiring?
    No, the actual receptacle circuits are 30amps.

      You make a good point here.


      The question for me is, will #18 trip a breaker when short circuited.

      Forgive all the silly questions. In part I want to say this is wrong, on the other hand I'd like to think engineers know something I don't.

        Everything shown are 230v loads?

          Yes


          Which may or may not inspire confidence.

                I do that sometimes.

                The question for me is, will #18 trip a breaker when short circuited.
                I believe that, yes, with typical circuit methods and lengths, a direct short will trip all small breakers at the same rate (for a given brand/type).

                Forgive all the silly questions. In part I want to say this is wrong, on the other hand I'd like to think engineers know something I don't.
                There's nothing to forgive; you're participating. This is exactly why forums like this exist. You're engaging in conversation and not argument.

                  Meaning it lacks a lot to be desired.

                    I'd say the solution in this case, judging by the panel schedule, is to use 30a devices.

                      See the attachments here, might be a bit better:

                      The outlets in this example will take the registers and plug in displays.

                      Ideally, but I doubt I could find any.

                        What do you need to plug in, both plug-wise and load-wise?

                          The plans show standard floor mounted convenience receptacles, which should be a standard 15 or 20a 125v duplex mounted in a floorbox, yet, they are shown being fed by a 2p 30a 230v branch circuit.

                          So, are they actually 15 or 20a 125v convenience outlets, or, 30a 230v 1ph special purpose outlets?

                          That's what I mean by "Jacked Up".

                            15 amp 230 volts convenience outlets.

                            The first set of drawings is for a store in a mall.

                            The second set is for the panels on the 4th floor feeding business related offices. By special purpose the mean dedicated to computers/cubicles.

                            Forgive me if the second one caused confusion, I only want to give an example of these 30amp circuits being used.

                              Table lamps, computers, cell chargers, microwave, coffee maker, ect. General use stuff. Its the thin cords that have me panicked.

                                It can't be both. 120v or 208v?
