B-LINE U215 MTBH MS45 – Frequently Asked Questions
1) Will the Eaton B-Line U215 MTBH MS45 meter breaker work on a 3-phase 4-wire 120/208V service?
Yes. The U215 MTBH MS45 is built for 3-phase, 4-wire service: 3 poles, 7 jaws, rated 100 A. The 7-jaw socket is the standard configuration for a 3-phase 4-wire network meter, so it will not suit a single-phase 4-jaw or 5-jaw application.
2) Can this B-Line meter breaker be installed outdoors?
Yes, it's a Type 3R enclosure, which is rain and sleet tight for outdoor wall mounting. The shell is galvanized steel finished in ANSI 61 gray paint, and it's a surface mount unit, so it bolts to the exterior wall rather than recessing into it.
3) What wire sizes will the lugs on this 100 A meter breaker take?
Both line and load terminations accept #14 through 2/0 conductors. That covers typical copper or aluminum feeders for a 100 A service, including 2/0 aluminum SER or USE cable.
4) Is this meter socket a ringless or ring type cover?
Ring type. If your utility specifies a ringless socket, this is the wrong unit, and swapping covers after the fact is not an option. Confirm which style your serving utility requires before ordering, since it varies by territory.
5) Will this pass utility inspection for a west coast service installation?
It's EUSERC approved and UL listed, which is what most western utilities look for on a meter-main. The unit also includes a test block, which many utilities require for metering verification on 3-phase services.
6) How much wall space do I need for this meter breaker combo, and how far does it stick out?
Plan for 24 inches of height by 18 inches of width, with a depth of 4.625 inches off the wall. It weighs 37 lb, so it's a one-person set but worth pre-anchoring before you hang it.
7) What is the short circuit rating on the breaker in this Eaton B-Line meter pack?
The main breaker is rated 22 kAIC. The enclosure assembly carries a 10 kAIC rating, so on services with higher available fault current you'll need to verify the utility's calculated fault duty at the service point.
8) Does this come with the main breaker, or do I order that separately?
The breaker is part of the assembly. It's a combination meter socket and main breaker unit, 100 A, 3 pole, with the 22 kAIC rated breaker factory installed. You supply the conductors, conduit hubs and mounting anchors.
9) What exact part number should I give the supply house for this B-Line meter breaker?
Order Eaton B-Line model U215 MTBH MS45. That's the 100 A, 7 jaw, 3 pole, ring type, 3R combination unit with test block.
