Hey guys, Im coming out of a weatherproof disco. with 4/0 SER. Im actually coming out of the back of the disco into the house. The builder wanted me to use 5/8 strut to hold the meter and disco off the house so he could install the siding behind the boxes at a later time. Supply house tells me they dont carry anything and to cut the bushing in a SEU connector or use duct seal to wrap my NM connector going into the back of the box. Any thoughts? should be good? Im thinking of just gobbing duct seal all over the back of the connector. Much better then taking the SER out and refeeding it through.
