What does excess charge mean?

    The interior of a conductor can have no excess charge in the static situation.
    What does excess charge mean here?as far as I know there can be no net charge at all in the interior of a conductor.So,is net charge same as excess charge?

    Excess charge means more positive charges than negative charges, or vice versa.

    I thin that "there can be no net charge" is not a correct usage. It is an abuse of language that I have often hear, with the meaning that "there can be no net charge other than zero." The correct way to say it is that the net charge is zero, which is the same as "no excess charge."
