Milbank U7375-RL-KK – Frequently Asked Questions

1) Does the Milbank U7375-RL-KK meter socket come with a main breaker installed?
No. The U7375-RL-KK is a provision-only socket: the main breaker count is zero, and the enclosure is prepped to accept a breaker you supply separately. Order the breaker and any mounting hardware as a separate line, or pick a factory-assembled meter-main if you want the breaker already in place.
2) What size service conductors will land in this 100A Milbank ringless socket?
The line side terminals take 6 AWG through 2/0 AWG copper or aluminum conductors, and they are lay-in style, so you drop the conductor into the terminal rather than fishing it through a hole. That range covers a typical 100A service run. Equipment grounding is handled by a 3 barrel ground lug.
3) Is this Milbank socket set up for an overhead service drop or an underground lateral?
Overhead. The U7375-RL-KK is built for overhead cable entry with a small hub opening at the top for your weatherhead conduit. If you are feeding from an underground lateral, this is the wrong configuration and you want a bottom-fed socket instead.
4) Will a 4-jaw ringless socket work on my utility's 120/240V single-phase residential service?
That is exactly what the 4 terminal configuration is for: single phase, up to 240 volts AC, 60 Hz, self-contained metering at 100 amps continuous. A 3-phase service or a network meter needs a 5-jaw or 7-jaw socket, not this one. Utilities differ on whether they accept ringless or ring-type, so confirm the ringless cover with your serving utility before you set it.
5) Can the Milbank U7375-RL-KK be mounted outdoors on an exterior wall?
Yes, it is UL Listed with a Type 3R rainproof enclosure, which is the standard rating for an outdoor wall-mounted service entrance. It is surface mount, so it fastens to the face of the wall or a meter pole board rather than recessing into the wall. Body is G90 galvanized steel with a powder coat finish, and the jaw insulation is glass polyester.
6) What does horn bypass actually do on a meter socket, and do I need it?
Horn bypass lets a lineman or meter tech shunt current around the meter so the meter can be pulled or swapped without killing power to the building. On occupied rental property, a medical facility, or anything with tenants, that is the difference between a five minute meter change and a service outage. Plenty of utilities require bypass on their 100A sockets; if yours does not, a non-bypass socket does the same metering job.
7) How much wall space do I need for this Milbank 100A socket, and will it cover my old socket's footprint?
Overall size is 3.75 in L x 8.125 in W x 22 in H, so it is a tall, narrow can about 3-3/4 inches deep off the wall. That 22 inch height is driven by the breaker provision section below the meter. If you are swapping out a plain meter-only socket, expect it to be noticeably taller than what is there, and plan for fresh mounting holes plus enough clearance below for the conduit or breaker enclosure.
8) Can I feed more than one unit from this Milbank meter socket?
No. It is a single meter position with one branch circuit off the main breaker provision, so it serves one metered service only. For a duplex, a small apartment building, or any multi-tenant property that needs separate billing, you want a multi-position meter stack, not this single socket.
9) What exact Milbank part number should I put on the purchase order?
Milbank U7375-RL-KK. It is the 100A, 1-phase, 4 terminal ringless socket with horn bypass, small hub opening, and main breaker provision, from the MTMN meter-main family. Cite the full suffix when ordering, since Milbank uses the trailing letters to separate bypass and hub configurations within the same base number.
10) Does this Milbank socket include a receptacle for a generator or maintenance power?
No receptacles are built into the U7375-RL-KK. It is metering plus a breaker provision, nothing else. If you need a generator interlock or a service outlet at the meter, that gets added as separate equipment downstream.
