Milbank U4702-X 400A Meter Socket Ringless 1-phase 600V

Product Description

The MILBANK U4702-X is a single-position, ringless-type meter socket designed for 1-phase electrical service installations. Rated at 400 amperes and 600 VAC at 60 Hz, it accommodates both overhead and underground service entry configurations. The enclosure is fabricated from powder-coated G90 galvanized steel and carries a NEMA 3R rating for outdoor, surface-mount applications. The socket uses a 4-jaw design with a lever-style bypass switch, allowing utilities and licensed electricians to perform meter pulls without a full service disconnect. Termination is made via 3/8 inch-16 TPI stud connections on both the line and load sides. UL listed.

The U4702-X is suited for residential and light commercial electrical service entrances where a single meter position is required. Its overhead and underground compatibility makes it a flexible choice for new construction and retrofit installations. The large closing plate hub and concentric knockouts accommodate a wide range of conduit sizes. The lever bypass switch meets utility requirements in many jurisdictions, making this socket a standard specification item for metering installations handled by licensed electricians and utility contractors.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local utility requirements. De-energize the service and coordinate with the utility for meter removal before working on line-side terminations. The NEMA 3R enclosure requires surface mounting on a structurally sound wall or panel board. Verify local utility approval of the lever bypass type before installation, as some jurisdictions specify bypass switch requirements.
