Milbank U3491-XL-200 – Frequently Asked Questions

1) What amp ratings does the Milbank U3491-XL meter socket with main breaker come in?
Two main breaker sizes: 150 amp (U3491-XL-150) and 200 amp (U3491-XL-200). Everything else is the same between them, 4 terminal, single position, 1 phase, up to 240V AC at 60 Hz. Pick the breaker to match the service size the utility is feeding.
2) Can this Milbank meter socket be mounted outside on the exterior wall of a house?
Yes. The U3491-XL is a Type 3R UL Listed enclosure, which is the outdoor rainproof rating used for service entrance equipment on an exterior wall. Body is G90 galvanized steel with a powder coat finish, and it surface mounts flat to the wall.
3) Will this Milbank socket work for an underground service lateral, or is it overhead only?
Either one. Cable entry is rated for overhead or underground service, so the same can handles a weatherhead drop from above or a lateral coming up from below. It ships with a small closing plate at the hub opening, so if you are running overhead you remove the plate and install the appropriate hub.
4) Is this a combination meter main, or do I still need a separate disconnect?
It is a meter main. One meter position and one integrated main breaker in the same enclosure, so the service disconnect is built in and you do not need a separate disconnect between the meter and the panel. There are no branch breaker spaces and no receptacles, so all branch circuits still feed from a downstream load center.
5) Can I use this Milbank socket on a 3-phase or 208V service?
No. This is a single phase unit with 4 terminals rated up to 240 volts AC, which suits standard 120/240V single phase residential and light commercial service. A three phase service needs a 7-jaw socket and a three phase rated can, not this one.
6) What are the dimensions of the Milbank U3491-XL meter socket enclosure?
The can measures 4.125 inches deep by 12 inches wide by 29 inches high. The 29 inch height is worth checking against your wall space, because the meter has to sit within the utility's required height window off finished grade and there needs to be room below for the main breaker section and conduit.
7) What does ringless mean on a Milbank meter socket, and does it change what I order?
Ringless means the cover slides down over the meter and is secured by the utility, instead of a separate sealing ring clamping the meter to the socket. Utilities specify one or the other and they are not interchangeable in the field, so if your utility is a ring-type territory, a ringless can will get red tagged at inspection. The U3491-XL is ringless.
8) How well does this meter socket hold up in coastal or high-humidity conditions?
Construction is G90 galvanized steel with a powder coat over it, so there are two layers of corrosion protection on the enclosure, and the Type 3R rating covers rain, sleet and ice. Internally the jaw assembly is insulated with glass polyester, which handles heat and moisture better than a phenolic base. For property managers standardizing on exterior service gear across a portfolio, that is the durability spec to compare on.
