B-LINE 225 MTBH MS45 – Frequently Asked Questions
1) Will the B-Line 225 MTBH MS45 meter breaker work on a single-phase 120/240V residential service?
Yes. The 225 MTBH MS45 is built for 1 phase, 3 wire service with a 5 jaw meter socket, which is the standard single-phase self-contained residential/light commercial arrangement. It is a single position unit, so it serves one meter only. For a multi-tenant building you need a multi-position meter pack instead.
2) Can the 225 MTBH MS45 meter breaker be installed outdoors?
It is rated NEMA 3R, so it is suited to outdoor surface mounting on an exterior wall, protected against rain and sleet. The enclosure is steel finished in ANSI 61 gray paint. 3R is not washdown or dust-tight, so keep it off hose-down and heavy dust locations.
3) What size service conductors will fit the line lugs on this 200 amp meter breaker?
Line lugs on the 225 MTBH MS45 accept #6 through 250 MCM, so 4/0 aluminum or 2/0 copper service entrance conductors for a 200 amp service land directly without adapters. Load side terminates at the main circuit breaker.
4) Does this Eaton B-Line meter breaker meet utility EUSERC requirements?
Yes, the 225 MTBH MS45 is EUSERC approved and UL listed. EUSERC approval is what most western US utilities require before they will set a meter, so it is the box to ask for when the utility rejects a non-approved enclosure.
5) How big is the 225 MTBH MS45 enclosure and how much wall space do I need?
The enclosure measures 48 inches high, 14 inches wide, and 6 inches deep, and weighs 56 pounds. Plan for a two-person set on the wall and check that the 48 inch height still leaves the meter center within the utility's required mounting height window.
6) Does this meter breaker have a bypass so the utility can pull the meter without killing the load?
It uses a test block rather than a lever bypass. A test block lets the utility connect test equipment and transfer load during meter work. If your utility specifically requires a horn bypass or lever bypass socket, this is not the unit to order.
7) Is the meter cover on the 225 MTBH MS45 a ring type or ringless?
Ring type. The 225 MTBH MS45 uses a ring style cover door, so it takes a sealing ring around the meter rather than a ringless hinged cover. Utilities generally specify one or the other, and the two are not interchangeable on the same enclosure.
