    Test tomorrow, one last question

    From PSI practice test, What is the minimum size copper conductor permitted for use for a 6,000 volt service? Answer is 6AWG. Where is a code reference to sizing wire based on voltage?
    Other than that I think I'm ready. head only moderately spinning from the last month of study. Thanks, Don

    Never heard of a 6000V service. You don't size wires based on voltage, you size them based on amperage. I've taken about nine PSI exams and never seen that question.

    6000V?
    If you aim at nothing, you will hit it every time!

    6000V. That was cut and paste from the test. Your responses tell me what I needed to know, think it's a goof up question. Thanks Gents and to all a good night

    That question and answer appear halfway down this page: https://quizlet.com/137528490/previo...s-flash-cards/

    I used the Find function for "6,000" to find it once I was on the page.

    Perhaps that will at least help, by looking at the source and other claimed "previous questions."

    Could be they were thinking of this:

    VIII. Services Exceeding 1000 Volts, Nominal230.200 General. Service conductors and equipment used
    on circuits exceeding 1000 volts, nominal, shall comply
    with all the applicable provisions of the preceding sections
    of this article and with the following sections that supple-
    ment or modify the preceding sections. In no case shall the
    provisions of Part VIII apply to equipment on the supply
    side of the service point.
    Informational Note: For clearances of conductors of over
    1000 volts, nominal, see ANSI C2-2007, National Electri-
    cal Safety Code.
    230.202 Service-Entrance Conductors. Service-entrance
    conductors to buildings or enclosures shall be installed to
    conform to 230.202(A) and (B).
    (A) Conductor Size. Service-entrance conductors shall not
    be smaller than 6 AWG unless in multiconductor cable.
    Multiconductor cable shall not be smaller than 8 AWG.

    I think that since many of us don't deal with it on a regular basis that we tend to overlook the over 1000 volt stuff. IMO the 6000 volts is just there for confusion.

    How about 310.106(A) and Table 310.106(A).

    At 5001 to 8000 Volts the minimum copper conductor size is #6.

    I guess that backs up what Trevor stated
