Milbank U5101-XL-11GR – Frequently Asked Questions

1) Will the Milbank U5101-XL meter socket work on a standard 120/240V single phase residential service?
Yes. The U5101-XL is a 4 jaw, single phase socket rated up to 240 volts AC at 60 hertz, which is the standard single phase residential service arrangement. Four jaws is the correct count for a self-contained single phase 3 wire meter. If the utility meter on the job is a 5 jaw or 7 jaw form, this is not the right socket.
2) Can this Milbank ringless socket be installed outdoors on an exterior wall?
Yes. The enclosure is UL Listed and Type 3R rated for outdoor use, built from G90 galvanized steel with a powder coat finish for corrosion resistance. It surface mounts to the wall, so no flush pocket or backbox cutout is needed.
3) Does the U5101-XL socket come with a main breaker, or do I need a separate disconnect?
It depends on which configuration you order. The plain U5101-XL is a meter socket only, with no overcurrent device, so the service disconnect goes downstream. If you want the disconnect in the can, order U5101-XL-100MB-11GR, which is built with a 100 amp main breaker, or U5101-XL-100MB-KK-11GR for that same breaker with horn bypass.
4) Which Milbank U5101-XL part number do I order if the utility requires a horn bypass?
Two configurations carry the horn bypass: U5101-XL-KK-11GR, which is a straight socket with bypass and dual 520GR lugs, and U5101-XL-100MB-KK-11GR, which adds a 100 amp main breaker. The bypass lets the meter be pulled without dropping the load, and several utilities require it on commercial and multi-family service.
5) Will the U5101-XL meter socket work for an underground service lateral, or only overhead?
Both. Cable entry is rated overhead or underground. It ships with a small closing plate on the hub opening, so for an overhead drop you swap that plate for the hub size your raceway needs; for an underground lateral the conduit typically comes in through the bottom and the plate stays.
6) What is the difference between a ringless meter socket and a ring type socket, and which do I need?
A ringless socket like the U5101-XL uses a removable cover held by the utility seal instead of a locking ring around the meter rim, so the meter is accessed by lifting the cover rather than cutting a ring. Which one you install is dictated by the serving utility, not preference. Many utilities specify ringless for residential and light commercial; if yours specifies ring type, this socket will not pass inspection.
7) What do the GR and GB suffixes mean on the Milbank U5101-XL part numbers?
They call out the lug or connector kit factory-installed in the can. U5101-XL-11GR and U5101-XL-KK-11GR carry dual 520GR, while U5101-XL-76GBGR combines a 1450GB with a 520GR. Pick the one that matches the conductor arrangement the utility wants landed. The base U5101-XL ships without those added connectors.
8) How much wall space does the Milbank U5101 meter socket need?
Plan for a 25 inch tall by 8.875 inch wide footprint on the wall, plus the working clearance in front that the utility and code require at the meter. It mounts to the surface, so nothing is recessed behind it.
9) Can I standardize the same meter socket across a multi-unit property and still meet different utility requirements?
The U5101-XL family gives you one 4 terminal ringless single phase body in six build-outs, so the can, footprint and 6 AWG to 350 kcmil wire range stay constant while you vary bypass and breaker. That keeps one spare configuration on the shelf for maintenance. What it cannot cover is a utility that requires ring type sockets or a meter form other than 4 jaw.
10) Is there a place to land the equipment grounding conductor in this socket?
Yes, a ground bar is provided for equipment grounding, so the EGC and, where the utility permits bonding at the meter, the grounding electrode conductor have a factory landing point. Jaw insulation is glass polyester.
