3-phase, four wire, 7 jaw meter sockets now come in a new can size, to facilitate both overhead utility entry and underground utility entry (the old product was overhead entry only, limiting the applications of use). They are available in two styles; Bonded Neutral (P27-0) and Isolated Neutral (P27-0-IN2). An accessory is also available to convert the bonded neutral version, to isolated neutral, by installing the isolated neutral kit, PN IN20. Bottom, side and back KO's can accommodate up to 3 inch Conduit.
