Milbank U2349-O – Frequently Asked Questions

1) Will a Milbank ringless meter socket with lever bypass work for an underground service lateral?
Underground entry is exactly what this Milbank socket is built for. The cable entry is underground and the top is a plain top hub closing plate, so there is no hub opening punched for an overhead mast. If your service drop comes in overhead, this is the wrong configuration for the job.
2) What amperage options does the Milbank ringless lever bypass meter socket come in?
Two amp ratings are offered: a 200A version, Milbank U2349-O, and a 320A continuous version, U6047-O-K3L-K2L. Both are single phase, single meter position, ringless with lever bypass and underground entry.
3) Does this Milbank meter socket include a main breaker or disconnect?
No. It is a meter socket only, with no main breaker in the enclosure. You will need a separate service disconnect or main breaker panel downstream to meet your service requirements.
4) Is a 4-terminal meter socket right for 120/240V single phase residential service?
Yes. The 4-jaw, single-phase configuration is the standard arrangement most utilities require for 120/240V single-phase residential and small commercial service. The enclosure is rated to 600 volts AC at 60 Hertz. Utilities do vary on jaw count and bypass requirements, so match the socket to your serving utility's approved list.
5) What wire sizes will the 320A Milbank meter socket terminals accept?
Line side lands 4 AWG through 600 kcmil, or two conductors of 1/0 AWG through 250 kcmil per phase. Load side takes two conductors from 6 AWG to 350 kcmil. Terminals are single mechanical type, so no crimp lugs are needed. That load side range is what lets a 320A service feed two 200A panels.
6) Can this meter socket be mounted outdoors on an exterior wall?
Yes. It is a Type 3R rain-tight enclosure, UL Listed, in G90 galvanized steel with a powder coat finish for outdoor wall use. It is surface mount, so it fastens to the face of the wall rather than recessing into it.
7) What does lever bypass do on a meter socket, and do I need it?
Lever bypass lets the meter be pulled and replaced without dropping power to the building, which is why most utilities require it on larger services. Throwing the lever shunts current around the meter jaws. If your utility only requires a horn bypass or no bypass at all, you can spec a simpler socket, but lever bypass is the safer choice for occupied buildings where an outage is a problem.
8) What are the enclosure dimensions of this Milbank socket, and will it fit my meter board?
The enclosure measures 4.844 deep by 15 wide by 30 high in inches. Lay that against your existing meter board or wall space before you demo the old socket, particularly the 30 inch height, which is taller than many 100A and 150A sockets it might replace.
9) Is a ringless meter socket the same as a ring-type socket?
No, and utilities are specific about which they accept. A ringless socket uses a sealable cover over the meter instead of a locking ring band around it. This Milbank unit is ringless. If your utility's spec calls for ring type, a ringless socket will be rejected at inspection.
10) Can one of these sockets meter two apartments?
No. This is a single meter position socket, so it serves one metered account. For a duplex or multi-unit building you need a multi-position socket or a meter stack with one position per tenant.
11) How does the ground get bonded in this Milbank meter socket?
Grounding is handled through a 3 barrel ground lug in the enclosure, so the grounding electrode conductor and equipment grounds land directly inside without adding a separate ground bar kit. Insulation on the jaw assembly is glass polyester.
