    I use standard Wiremold boxes for switches and receptacles under cabinets.

    Not my work, but similar (I don't use oversize plates):

    If it''s the number he has to work with for 230/240v, the corresponding number at 200/208v would be use in whatever calculations he's doing.

    So my 51.97a guess was right on the money. 47 + 4.7 = 51.7.

    I believe a 480v breaker's trip coil will operate on 120 to 480 volts, expecting the trip current to be momentary.

    Don't forget to calculate how much power (va) you'll be able to deliver per dollar each way, too.

    1ph wiring, where 3ph is practicable, is starting to look more expensive; and redundant.

    I do that sometimes. ;)


    Depends on the J-box, but I usually opt for 1ph runs vs 3ph runs. I wouldn't want to have to make any extra connections.

    Dave, that doesn't answer the question, which is: presuming why he's asking, for circuit calculations, the max current, corresponding to the 47a at 230v rating.

    So, you'd be using a delta configuration. A little unorthodox, but not unheard of. Will require 2-pole breakers likely require multi-pole switching, too.

    A motor draws more current at lower voltage, not less.

    I have no formula, but using the theory that a motor tends to be a constant-power load, I get 51.97a.

    You can check this against a couple...

    First, I'd use fewer 20a circuits. Second, you'd need 12-4 to supply three phases to a neutral. 3-conductor only gets you two circuits. You are using MC and not NM (presuming suspended ceilings),...

    It does, but if it doesn't, contact cement works very well. I even use it to affix wiring under cabinets.

    I think it won't mass muster if your plan is to use the seventh disconnect. Can you tap into the feeder and place a remote disconnect?

    I recommend contacting your AHJ first, and discuss this.

    Also look at GM lighting here: http://gmlighting.net/

    There are even edge-firing LED ribbons available.

    You'll need to pre-wire and coordinate with the carpenter.
