Milbank U225MTB-48 – Frequently Asked Questions

1) Will the Milbank U225MTB-48 meter socket work on a 480V three-phase service?
Yes. The U225MTB-48 is rated up to 480 volts AC, 3 phase, 60 Hz, with a 5 terminal jaw configuration. That 5 jaw arrangement is what a 3 phase 4 wire wye service uses. If your service is 3 phase 3 wire delta or a single phase 120/240V residential service, this is not the right socket, and the utility will reject the jaw count at inspection.
2) What size conductors can I land in this 200 amp Milbank meter socket?
Line side lugs take 6 AWG through 250 kcmil; load side takes 6 AWG through 350 kcmil. Both are single mechanical terminals, so one conductor per lug, no parallel runs. There is a ground lug for the equipment grounding conductor. At a full 200 amp continuous load you are typically landing 250 kcmil copper or 350 kcmil aluminum on the load side, which is exactly why the load side range runs larger than the line side.
3) Can this Milbank meter socket be installed outdoors on an exterior wall?
Yes. It is UL Listed with a Type 3R enclosure, which is the rain-tight rating for outdoor wall-mounted service equipment, built from G90 galvanized steel with a powder coat finish. It is surface mount, so it lands flat on the wall rather than recessing into it. Budget wall space for a unit measuring 6 x 22.125 x 30 inches.
4) Do I still need a separate main disconnect with this meter socket?
No separate main is needed. One 200 ampere main breaker is built in, so the U225MTB-48 is a combination meter socket and service disconnect in a single enclosure. That covers the service entrance disconnecting means and overcurrent protection at 200 amps. There are no branch breaker receptacles in it, so any downstream distribution goes to a separate panel fed from the load side lugs.
5) What does the link bypass on this Milbank socket actually do for me?
Link bypass lets the utility or meter tech shunt current around the meter so the meter can be pulled or swapped without dropping the customer. For a property manager or a facility with tenants, that is the difference between a five minute meter change and a scheduled outage. Many utilities require bypass on 200 amp commercial services, so confirm your utility accepts link bypass rather than a lever (horn) bypass before you order.
6) Can I feed this meter socket from an overhead drop, or does it have to be underground?
Either works. The U225MTB-48 accepts overhead or underground cable entry, and it ships with twin small closing plates covering the hub openings. For an overhead service you remove a closing plate and install the correctly sized weatherproof hub for your mast conduit; that hub is a separate item and is not included. Underground lateral entry comes in from the bottom.
7) How many meters can this Milbank ring type socket serve?
One. It is a single position socket with one meter and one 200 amp main breaker, so it serves a single service or a single tenant. For a multi-tenant building where each unit needs its own meter, you want a multi-position meter stack, not this unit.
8) Is this a ringless or ring type meter socket?
Ring type. The meter is secured with a sealing ring rather than a removable ringless cover, and most utilities specify one or the other in their service standards. If your utility requires ringless, this socket will not pass their inspection, so check the service handbook before ordering. The unit also uses an insulating base of fiberglass with resin behind the jaws.
9) What is the exact Milbank part number to order for a 200A 480V 3 phase meter main?
Order Milbank model U225MTB-48. It falls in Milbank's SS2B product family and carries UNSPSC 39121102 for procurement systems that require it.
