B-Line U2M2R Eaton series meter breakers, 200 A, Single meter position, Ring type, 3R, Underground, ANSI 61 gray painted, 010 kAIC, #6 - 250 MCM, MCB, (1) 200 A, 2P, Galvanized steel, Surface mount, 4 jaws, 3 wires, 1 phase, 1Ø/3W, 120/240 V

Yes, that is exactly what the U2M2R is built for. It is a single meter position combination meter socket and main breaker rated 200 A at 120/240 V, single-phase, with a 4 jaw socket and a 1 phase, 3 wire (1 phase/3 wire) configuration. The main breaker is one 200 A, 2 pole device. That matches a typical residential or small commercial overhead-to-underground 120/240 V service.

Underground. The U2M2R is configured as an underground feed meter breaker, so the service conductors come up into the enclosure from below rather than through a weatherhead and hub on top. If the job has an overhead service drop, you want the overhead version of the meter breaker instead, not this one.

The lugs accept #6 through 250 MCM conductors, which covers the usual 4/0 aluminum or 2/0 copper used on a 200 A service as well as parallel-free 250 MCM aluminum runs. Bus in the unit is aluminum, so use an antioxidant compound on aluminum conductors per the terminal instructions.

Yes. It is a Type 3R rainproof enclosure in galvanized steel with an ANSI 61 gray painted finish, intended for outdoor surface mounting on an exterior wall or a meter pedestal backboard.

Ring type. The cover uses a sealing ring to retain the meter, which is what many utilities specify. If your serving utility requires a ringless (lift-off cover) socket, this is the wrong unit and you need the ringless equivalent. Check the utility's approved meter equipment list before ordering, since this is the detail that gets a service rejected at inspection.

The unit is rated 10 kAIC at 120/240 V. That covers most residential and light commercial services fed from typical pad or pole transformers. If the utility provides an available fault current higher than 10,000 A at the service point, which can happen on short runs from large transformers, this assembly is not rated for that location and you need higher interrupting equipment.

It is a meter socket with a main breaker only, one 200 A 2 pole device, with no branch circuit spaces. You still feed a separate load center or panelboard downstream for branch circuits. That makes it a service disconnect at the meter, which also satisfies the outside disconnect requirement many utilities and inspectors want.

The U2M2R is EUSERC approved and UL listed. EUSERC approval is the acceptance standard used by most western US utilities for metering equipment, so the unit is built to that documented configuration.

Plan for a unit measuring 25 inches high by 14 inches wide with a 6 inch depth, weighing 35 pounds. It surface mounts, so on stucco or siding back it with blocking or a treated backboard so the fasteners hit structure, not just sheathing. Leave the NEC working clearance in front of the enclosure and keep the meter at the height the utility specifies.

Order it as Eaton B-Line U2M2R. That number carries the whole configuration: 200 A, ring type, 3R, underground feed, single meter position, with a 200 A 2 pole main breaker.
