B-LINE U215 MTBP MS15 – Frequently Asked Questions
1) Can the B-Line U215 MTBP MS15 meter breaker be mounted outdoors?
Yes. It is a Type 3R enclosure, which is the rainproof rating used for outdoor service equipment on an exterior wall. The housing is galvanized steel finished in ANSI 61 gray paint, and it is built for surface mounting rather than flush or recessed installation.
2) What service does a 7-jaw meter socket like this 100 A B-Line unit serve?
Seven jaws is the three-phase, four-wire configuration, so this is for a 3-phase 4-wire service at 100 A with a 480 V breaker. A single-phase 120/240 V service uses a 4-jaw socket instead, so don't order this for a residential or light single-phase drop.
3) What size service conductors will the lugs on this B-Line meter breaker take?
The wire range is #6 through 250 MCM, which covers copper or aluminum service entrance conductors sized for a 100 A three-phase service with room to oversize for voltage drop on a long run.
4) Is this B-Line meter breaker ring type or ringless, and does it have a test block?
Ring type, with a test block included. Ring type means the meter is retained by a sealing ring, which is what many utilities specify; if your utility requires a ringless cover, this is not the right unit. The test block lets the utility or a technician test and bypass the meter without pulling service conductors.
5) Will a utility accept this B-Line meter breaker for a new service?
It is UL certified and EUSERC Approved, which is the approval most western US utilities look for on service entrance equipment. Submit the model as U215 MTBP MS15 with your service application so the utility can confirm it against their approved list.
6) How many meter positions does the B-Line U215 MTBP MS15 have?
One. It is a single-position meter breaker, so it serves one tenant or one service point. For a multi-family building where each unit needs its own meter, you need a multi-position meter pack rather than this single-socket unit.
7) What are the enclosure dimensions and weight for planning the wall mount?
The cabinet measures 24 in high, 18 in wide and 4.625 in deep, and it weighs 40 lb. That weight and footprint means blocking or a structural backing behind the siding, and it is a comfortable one-person set on a flat wall.
8) Does this unit include the main circuit breaker or do I buy that separately?
The main circuit breaker is part of the assembly (MCB), rated for 480 V and matched to the 100 A three-phase four-wire service. You are buying a combination meter socket and main breaker in one enclosure, not a socket that needs a separate disconnect beside it.
