    Regarding the attachment of the overhead service mast to the meter/load
    panel, can teflon tape be used on the threads at the mast-to-flange
    connection? Or does this need to be electrically bonded (ie, no tape)?

    I was thinking of waterproof vs. electrical bond, and couldn't decide.

    Thanks.

    This may vary by locale, but I had to install grounding bushings on the
    threads of the pipe within the meter box to bond the mast conduit to the
    meter box ground lug. Same with the metal conduit going out the bottom
    to the service panel.
