B-LINE 217 MTBH MS15 – Frequently Asked Questions
1) Will the B-Line 217 MTBH MS15 meter breaker work on a 3-phase 4-wire 480V service?
Yes. The 217 MTBH MS15 is built for 3-phase, 4-wire service and carries a 480 V breaker, with a 7-jaw meter socket to match a 3-phase 4-wire metering arrangement. It is rated 100 A with a 42 kAIC interrupting rating, so it suits services where available fault current at the point of installation does not exceed 42 kA.
2) Can this Eaton B-Line meter breaker be mounted outdoors?
Yes. The 217 MTBH MS15 enclosure is Type 3R, which is the rainproof outdoor rating used for service equipment on an exterior wall. The body is galvanized steel finished in ANSI 61 gray paint, and it is a surface mount unit, so it bolts to the wall rather than recessing into it.
3) What size conductors will land in the line lugs on the 217 MTBH MS15?
Line side lugs accept #14 through 2/0 conductors. Load side terminates at the main circuit breaker. If your service entrance conductors are larger than 2/0, this unit will not take them directly and you need a different line lug arrangement.
4) Is this meter breaker approved for utility service in EUSERC territories?
It is EUSERC approved and UL certified. That matters in the western US, where most utilities require EUSERC-approved service equipment before they will set a meter. It uses a ring type cover door and a test block for bypass.
5) How many meter positions does the B-Line 217 MTBH MS15 have?
One. It is a single position meter breaker, so it serves one tenant or one service. For multi-tenant buildings you would need a multi-position meter stack instead of this unit.
6) How much wall space do I need for the 217 MTBH MS15, and how heavy is it?
Plan on 38 inches of height, 12 inches of width and 4.63 inches of depth off the wall. It weighs 38 lb, which is a two-person set on a ladder but manageable for one on a solid wall with the mounting hardware pre-started.
7) Does a test block bypass let the utility pull the meter without dropping the load?
That is what the test block is there for. The 217 MTBH MS15 uses a test block bypass, which lets the utility test or change the meter without interrupting service to the load. If your utility instead specifies a lever bypass, this is not the right unit.
8) Will a 100 A meter breaker like this hold up on a service with high available fault current?
The 217 MTBH MS15 is rated 42 kAIC, so it is suitable where the utility-calculated available fault current at the service point is 42 kA or below. Above that you need equipment with a higher interrupting rating or upstream current limiting. The overcurrent device itself is sized at 100 A.
