B-Line U214 MTBH MS45 Eaton series meter breakers, 100 A, Test block, Ring type, 3R, ANSI 61 gray painted, 042 kAIC, #6-250 MCM, MCB, Steel, Surface mount, 5 jaws, 1 position, 1Ø/3W, 22K AIC rated breaker

Yes. The U214 MTBH MS45 is a 1 phase, 3 wire meter breaker rated 100 A, which is the standard single phase service arrangement for a house, duplex unit, or small commercial tenant. It uses a 5 jaw meter socket, so the utility meter must be a 5 jaw form; a 4 jaw socket will not accept the same meter and vice versa. One breaker position, main circuit breaker type.

Yes. It is a NEMA 3R enclosure, rain tight for outdoor wall mounting, in galvanized steel with an ANSI 61 gray painted finish. It is a surface mount unit, so it lands on the face of the wall rather than recessing into it.

The terminals accept #6 through 250 MCM, so copper or aluminum service entrance conductors sized for a 100 A service land directly without adapters or reducers. That range also leaves room if the feeder was oversized for voltage drop on a long run.

It is EUSERC Approved, which is what most western US utilities require on metered service equipment before they will set a meter. It is also UL listed. Confirm the specific socket form and sealing requirements with your serving utility as part of the service application.

Ring type means the meter is retained by a sealing ring around the meter rim, and the utility seals that ring. Ringless sockets instead use a removable cover that the utility seals, and the two are not interchangeable, so order to match what your utility specifies. The U214 MTBH MS45 also includes a test block, letting the utility test or bypass the meter without pulling service conductors.

One. It has a single position with a main circuit breaker, so it meters the service and provides the service disconnect only. Branch circuits need a separate downstream panelboard or load center fed from that 100 A main. If you want the meter and the branch breakers in one can, you need a combination meter main load center instead.

Plan for 24 inches high by 18 inches wide, with 4.625 inches of depth off the wall. It weighs 35 lb, so it is a one-man lift onto the mounting fasteners but easier with a second set of hands while you hold it plumb.

Yes. B-Line is an Eaton brand, and this is catalogued as an Eaton B-Line series meter breaker. Order it by the model and manufacturer part number U214 MTBH MS45.
