Milbank U4413-O-KK-BL – Frequently Asked Questions

1) Will a Milbank U4413-O-KK ringless meter socket work for a 200 amp underground residential service?
That's exactly what the U4413-O-KK is built for. It's a single position, 4 terminal ringless socket rated 200 continuous amps at 600 VAC, 60 Hz, single phase, with underground cable entry and a side wireway for the service laterals. Both line and load lugs take 6 AWG through 350 kcmil, so it covers everything from a small 6 AWG feed up to parallel-free 350 kcmil copper or aluminum service conductors. Surface mount, Type 3R enclosure for outdoor walls.
2) Does the Milbank U4413-O-KK meter socket come with a main breaker or main disconnect?
No. The U4413-O-KK is a meter socket only, with no main breaker and no receptacles. You'll need a separate service disconnect downstream, and most utilities and inspectors will want it within sight or immediately adjacent per your local rules. If you need metering and the main in one can, you're looking for a meter main combination, not this socket.
3) What is horn bypass on a meter socket and do I need it?
Horn bypass gives the meter tech a way to carry the load around the meter so the socket stays energized while the meter is pulled or swapped. It's the reason the U4413-O-KK can have its meter changed without dropping power to the building. Many utilities require bypass on 200 amp residential and light commercial services, and some require it on any account they can't easily interrupt (medical, refrigeration, tenant occupied). If your utility spec sheet doesn't call for bypass, a non-bypass socket is the simpler part; if it does, this is the configuration you want.
4) Which Milbank U4413-O-KK version do I order for PEPCO or Delmarva Power?
There are utility specific versions of the U4413-O-KK: order U4413-O-KK-PEP for PEPCO approved installations and U4413-O-KK-DPL for Delmarva Power and Light. Meter sockets are approved by the serving utility, not by the electrician, so the approved variant is what gets past the meter set inspection in those territories. Outside those two service areas, the barrel lock versions are the general purpose choices.
5) What's the difference between the 9/16 inch and 7/8 inch barrel lock versions of the U4413-O-KK?
It's the size of the barrel lock provision the utility's sealing lock drops into. U4413-O-KK-BL takes a 9/16 inch barrel lock; U4413-O-KK-BLG takes a 7/8 inch barrel lock. The socket itself is the same 200 amp, 4 terminal, horn bypass ringless unit either way. Match the hole to whatever barrel lock your serving utility uses, otherwise the meter tech can't seal the cover.
6) Can I bring conduit in through the top of this Milbank socket?
Not without cutting it. The U4413-O-KK ships with a plain top, meaning no factory hub opening, and it's configured for underground entry through the side wireway. If your service drop is overhead and you need a hub, you want a hub top or hub opening version of the socket rather than the plain top. For an underground lateral coming up from a trench or riser, plain top is correct and keeps the top of the can weathertight.
7) Will 4/0 aluminum service entrance cable land in this meter socket?
Yes. The U4413-O-KK takes 6 AWG through 350 kcmil on both the line and load lugs, so 4/0 aluminum, the usual conductor on a 200 amp residential service, lands well inside the range. So does 2/0 copper, and there's room up to 350 kcmil if the utility spec or a long lateral pushes you to upsize. The terminals are lay in type, so the conductor drops into the lug rather than threading through.
8) How much wall space do I need for this Milbank 200A meter socket?
Plan on roughly 15-1/4 by 13 by 4-1/2 inches for the can itself, before you add the working clearance and meter height your utility requires. It's a surface mount enclosure, so it lands flat on the wall or on a meter board rather than recessing in. On a stucco or brick wall, mount to a backer board so the underground wireway isn't fighting an uneven surface.
9) Is this meter socket OK to mount outdoors in rain and ice?
Type 3R rated and UL Listed, so it's built for outdoor wall mounting and protects against rain, sleet, and ice formation. The enclosure is G90 galvanized steel with a powder coat finish, which is the standard corrosion package for exterior service equipment. Internal insulation is glass polyester. For coastal or heavy chemical exposure, a stainless enclosure is the step up.
10) Does a 4 terminal ringless socket work for 120/240V single phase, and when would I need 5 or 7 jaw instead?
Four jaws is the standard single phase, 3 wire configuration, which is what a 120/240V residential or light commercial service uses, and the U4413-O-KK is rated 1 phase at 600 VAC. Go to 5 jaw when the utility meters a network or requires a neutral jaw arrangement they specify, and 7 jaw when the service is three phase. Ringless means the cover slides over the socket and is sealed with a barrel lock instead of a sealing ring, so check which style your utility accepts before ordering, since some territories still require ringed.
11) Is there a ground lug in the Milbank U4413-O-KK or do I add a ground bar?
An equipment ground lug is included in the socket, so you have a landing point for the grounding electrode conductor or equipment ground without adding a kit. Whether the neutral is bonded to the can at the meter or at the service disconnect is a utility and jurisdiction call, so follow the serving utility's meter spec on the bond.
12) I manage a small apartment building. Can I use these to meter each unit?
Each U4413-O-KK holds one meter position, so you'd need one socket per metered unit or account. That works fine as individual sockets on a wall for a small building, and standardizing on one part number across the property means one spare on the shelf and one bypass procedure for the meter tech. For a larger stack, a multi position meter pack ganged in a single enclosure is usually the cleaner install than a row of individual sockets.
