    Panelboard wire bending space

    I have a 600 amp I-Line panel board. It has a square d, 3 pole subfeed kit (that feeds another panel) installed in one of the branch breaker positions with parallel 350 MCM conductors landed on it. For wire bending space I believe I can use 312.6(A), 1 wire per terminal value of 5 inches as the subfeed kit has 3 lugs per pole. Is this correct or do I have to use the 8 inch value?

    Also the current conductors for the circuit exit the back of the panel, are there minimum distance requirements for how far these conduit entries must be from the terminals of the subfeed kit?

    Input, feedback, ridicule? All welcome. Thanks.

    This may not apply but I'll offer it.
    We ran feeders for a MCC that was 900 amps or close too. The MCC had its own main breaker installed.
    The ahj said 13" was the minimum distance from entry to breaker for our situation. I think we had 11"
    I had to retap the mounting assembly for the breaker to be 13.5. "
    The hardest faults to clear are mine
