Milbank U224MTB/22 – Frequently Asked Questions
1) What is the difference between the 224MTB/22 and 227MTB/22 Milbank meter sockets?
Terminal count. The 224MTB/22 is a 4-terminal ring-type socket and the 227MTB/22 is a 7-terminal version. Four terminals covers single-phase 3-wire service; seven terminals is the configuration utilities call for on network or three-phase metering. Your serving utility's meter spec sheet dictates which one they will accept, so match the terminal count to their requirement before ordering.
2) What does the U prefix mean on the Milbank U224MTB/22 meter socket?
The U indicates the socket is built for combination overhead and underground service entrance, rather than overhead only. U224MTB/22 and U227MTB/22 are the overhead-and-underground versions; 224MTB/22 and 227MTB/22 are the overhead-only builds. If the feed comes in from a lateral below grade, or you want the flexibility to take it either way, order the U version.
3) Is the Milbank MTB a ringless socket?
No. The MTB is a ring-type socket, meaning the cover is secured with a sealing ring around the meter. Utilities are specific about this: if the local spec calls for ringless, a ring-type socket will fail inspection and the meter will not be set. Confirm ring versus ringless with the utility before you order.
4) Does this Milbank socket come with the main breaker included, or do I buy that separately?
It is a meter-main: the socket and the main breaker are one assembly, with the breaker sized 1 to 200 amperes. That is the difference between this and a plain meter socket, where you would have to feed a separate disconnect downstream. Buying the combination saves the second enclosure and the nipple between them.
5) What is a link bypass meter socket and do I need one?
Link bypass lets the utility shunt current around the meter through bypass links so the meter can be pulled or changed without dropping the customer's power. Many utilities mandate it on 200 amp services; others accept a non-bypass socket. The Milbank MTB series is a link bypass, ring-type socket with a small closing plate, so check that combination against your utility's approved meter equipment list.
6) I need to order Milbank meter mains for several buildings. What do I have to specify?
Two choices settle it. First, service entrance: overhead only (224MTB/22, 227MTB/22) or combination overhead and underground (U224MTB/22, U227MTB/22). Second, terminal count: 4 or 7. All four builds share the ring-type small closing plate, link bypass construction, 1-200 amp main breaker and 22K AIC rating, so once the utility spec is known the part number falls out of those two answers.
