B-Line Eaton series meter s, 100 A, Single meter position, Ring type, 3R, Underground, ANSI 61 gray painted, 010 kAIC, #14 - 2/0, MCB, 100 A, 2P, Gal

Yes. The U1M1R is built for 120/240 V, single-phase, 3-wire service with a 4-jaw meter socket, which is the standard residential and small commercial overhead/underground arrangement. It carries one 100 A, 2-pole main breaker and is rated 100 A overall.

Underground. The U1M1R is configured for underground service entrance, so it has no weatherhead/overhead hub provision. If the utility is feeding you from a pole with an overhead drop, you need an overhead-configured meter breaker instead.

It's a ring type socket, meaning the cover is retained by a sealing ring rather than a ringless-style bolted-on hub cover. Most utilities specify one or the other, so match the utility's requirement before ordering, as a ringless utility will reject a ring type can.

The lug range is #14 through 2/0, covering the usual copper and aluminum conductors used on a 100 A service. Bus is aluminum, so use the appropriate dual-rated compression or mechanical lugs and anti-oxidant compound on aluminum conductors.

Yes. It's a NEMA 3R enclosure, rain-tight for outdoor surface mounting, in galvanized steel with ANSI 61 gray paint. Mounting is surface, so it bolts flat to the wall or a strut rack rather than recessing into the wall.

Yes, the U1M1R is EUSERC Approved and UL listed. That matters in the western states where utilities require EUSERC-conforming metering equipment before they will set a meter and energize the service.

The main breaker in the U1M1R is rated 10 kAIC at 120/240 V. On a typical residential or small commercial 100 A single-phase service that is normally adequate, but if the utility's available fault current at the service point exceeds 10 kA, you need equipment with a higher interrupting rating. Ask the utility for the available fault current before you commit.

It's a meter-main combination: one meter position with a single 100 A, 2-pole main breaker. There are no branch breaker spaces, so you feed a separate load center downstream for your branch circuits. If you want metering and branch circuits in one can, you need a meter load center rather than this meter breaker.

Plan for 24 in high by 14 in wide, with 4.625 in of depth off the wall face. It weighs 28 lb, so one person can hang it, but block or strut backing is worth having on stucco or siding. Leave the working clearance your local code requires in front of the meter.

No. The U1M1R has one meter position only. A two-unit building needs a two-position meter stack or two separate meter breakers, one per tenant, per the utility's metering requirements.
