    Is there a disconnect or panel at the meter. You CANNOT simply come out of an existing meter.

    You would need #6cu or #4al conductors in conduit. If you run cable then #4cu or #3al.

    Thanks for the response;
    There is a breaker panel under the meter can with multiple blanks for the breakers.

    What breaker would be required for this application and would I have to be concerned about a voltage drop over for this length of run?
