Milbank U2228-XT – Frequently Asked Questions

1) Will the Milbank U2228-XT meter socket work for a 400 amp single phase residential service upgrade?
Yes for the metering portion. The U2228-XT is a single position, 6 terminal ringless socket rated 400 continuous amps, 1 phase, 600V AC, 60 Hz. It has no main breaker and no bypass, so the service disconnect and overcurrent protection have to be provided separately downstream. For a 400A residential upgrade that normally means a separate main breaker enclosure or a 400A disconnect fed from the socket.
2) Does the Milbank U2228-XT have a meter bypass for pulling the meter without dropping the load?
No. The U2228-XT is a no-bypass socket, so the load goes dead when the meter comes out. It does include a test switch provision, which lets the utility land test equipment for meter verification. If the utility on your job requires a lever or horn bypass socket, this is the wrong catalog number and you need a bypass version.
3) Can this Milbank ringless socket be used for underground service, or is it overhead only?
Both. Cable entry is rated for overhead or underground, and the enclosure carries twin large closing plates so you can punch for a service hub at the top for an overhead drop, or leave the top closed and come in from the bottom for an underground lateral.
4) Is the U2228-XT meter socket rated for outdoor mounting on an exterior wall?
Yes. It is UL Listed with a Type 3R enclosure rating, which covers rain, sleet and falling water on an outdoor wall. The box is G90 galvanized steel with a powder coat finish, and it is a surface mount design, so it lands flat on the wall rather than being recessed into the stud cavity.
5) How much wall space do I need for the Milbank U2228-XT meter socket?
The enclosure measures 12L x 24W x 34H inches, so plan on a 24 inch wide by 34 inch tall footprint on the wall with 12 inches of depth off the face. It surface mounts, so add working clearance in front per code and set the meter center at the height your utility specifies.
6) What is the difference between a ringless meter socket and a ring-type socket, and which one do I order?
It comes down to how the cover is retained. A ringless socket like the U2228-XT uses a lift-off front cover held by the socket itself, with a screw cover hasp for sealing, instead of a separate sealing ring clamping the meter in place. Most utilities specify one style or the other for their territory, so the deciding factor is your utility's service requirements document, not the installation. If they call for a ring-type, this one will not be accepted.
7) Can I meter two apartments with one Milbank U2228-XT, or do I need a multi-position socket?
One socket, one meter. The U2228-XT is a single position unit with no receptacles, so it serves one metered account. For a duplex or multi-family building where each unit gets its own meter, you need a multi-position meter stack or individual sockets per unit, not this single socket.
8) Is the Milbank U2228-XT suitable for a 3 phase 208V commercial service?
No. It is a 1 phase, 6 terminal socket. Three phase metering needs a 7 jaw socket wired for the utility's 3 phase 4 wire service. Use the U2228-XT only on single phase services up to 600V AC.
9) What is the exact Milbank part number to order for this 400A ringless socket with test switch provision?
The catalog number is Milbank U2228-XT, a 400A 1 phase 600V ringless socket with 6 terminals, test switch provision, twin large closing plates and a lift-off front screw cover hasp. One model covers this configuration, so there are no suffixes or options to pick on top of it.
10) Does the Milbank U2228-XT include a grounding provision for the equipment ground?
Yes, it ships with a ground lug for the equipment grounding conductor. Insulation on the jaw assembly is glass polyester, and the terminals are single mechanical type. Bonding of the neutral and the grounding electrode conductor connection are still per your local utility and code requirements.
