    Regarding your question, voltage drop is a Recommendation not a requirement. That said the recommendation is 5% end to end.

    So, I have a couple of questions for you:

    1) How long is the run from the main service panelboard to the end of the run?
    2) What is the amperage that you need at the end of the run?
    3) What size (AWG) and type is the cable?

    Once I have that information I can size the cables for you.
