An electrical conduit ground assembly is provided for electrically and environmentally shielding an electric cable that inserts into a junction box via a through-hole. The assembly includes an adapter flange, first and second annular gaskets, first and second annular washers, a slip-ring, a ground adapter, first and second lock-nuts and a gland nut. The adapter flange has an internally threaded proximate end, an externally threaded mezzanine, a hexagonal seat, and an externally threaded distal end insertable into the through-hole. The first annular gasket inserts into the proximate end. The first and second washers insert into the proximate end. The annular ground adapter electrically connects the cable and the annular conduit between the first and second washers. The second annular gasket has an annular shaft and a circular brim. The gland nut screws into the proximate end of the adapter flange.
