Milbank U4905-X-K3-K2 – Frequently Asked Questions

1) Does this Milbank socket include a main breaker or disconnect?
No. The U4905-X is a meter socket only, with no main breaker and no receptacles. Overcurrent protection has to come from the panel or disconnect you feed downstream of it, so budget separately for the service disconnect gear your inspector requires.
2) Can this Milbank meter socket be mounted outdoors on the side of a building?
Yes. It is UL Listed and Type 3R rated for outdoor rain-tight service, built from G90 galvanized steel with a powder coat finish and glass polyester insulation. Mounting is surface mount, so it fastens flat to the wall or a backboard.
3) Which Milbank U4905-X option do I order if the utility wants a 5th terminal?
Order U4905-X-5T9, the version with the 5th terminal at the 9 o'clock position. The plain U4905-X is the 4-terminal standard build. Two other configurations are offered: U4905-X-BLG with the barrel lock provision, and U4905-X-K3-K2 with the K3/K2 connector configuration. Utilities differ on 5th terminal position, so match the drawing they issued you.
4) Can I use this Milbank socket on a three-phase service?
No. The U4905-X is single phase, one phase only. A three-phase metering installation needs a three-phase socket with the correct terminal arrangement for that service, not this can.
5) How much wall space do I need for the Milbank U4905-X meter socket?
The enclosure measures 5.75 L x 16 W x 38.75 H inches. That 38-3/4 inch height is the number to check against your meter height requirement and any window, hose bib, or gas meter clearance on the wall before you set it.
6) What is the difference between a ringless meter socket and a ring-type one?
A ringless socket like the U4905-X has no separate sealing ring; the utility's cover plate slides over the meter and is sealed directly to the enclosure. Many utilities specify ringless and will reject a ring-type can, so confirm which style your serving utility requires before ordering. This one is ringless with a large closing plate at the hub opening.
7) Why does this Milbank socket have a lever bypass, and do I need it?
The lever bypass lets the meter be pulled and reinstalled without dropping power to the building, which is why most utilities require bypass on 320 amp class sockets. If your utility allows a non-bypass can, you do not need it, but a bypass socket can be installed where a plain one is accepted, not the other way around.
8) Does this meter socket accept a utility barrel lock?
Yes, through the barrel lock provision: a 7/8 inch knockout with an angle bracket. If your utility seals with barrel locks rather than wire seals, order the U4905-X-BLG configuration so the bracket is factory fitted.
9) Is the large closing plate on this socket for a hub, and is the hub included?
The hub opening is covered by a large closing plate, which is what you remove when you fit a conduit hub for overhead service. The plate itself is part of the enclosure; the hub sized to your service conduit is a separate item, so order it with the socket if you are going overhead rather than underground.
