B-LINE 214 MTBH MS45 – Frequently Asked Questions
1) Is the B-Line 214 MTBH MS45 meter breaker single phase or three phase?
It's a single phase, 3-wire (1 phase/3W) unit with a 4-jaw meter socket, so it's for standard 120/240V residential and light commercial single phase service. If your service is three phase, this is the wrong socket configuration.
2) Can the 214 MTBH MS45 meter breaker be installed outdoors?
Yes. The enclosure carries a 3R rating, which is the standard outdoor rating for rain and sleet on service equipment, and the galvanized steel body is finished in ANSI 61 gray paint. It surface mounts to a wall or structure rather than being flush set.
3) What size conductors will fit the line lugs on this Eaton B-Line meter breaker?
The line lugs accept #14 through 2/0 conductors, so a 2/0 copper or aluminum service entrance conductor is the largest it will take. Load side terminates at the main circuit breaker (MCB). If your service run is sized above 2/0, you need a larger lug range than this unit provides.
4) What amperage and interrupting rating does the 214 MTBH MS45 have?
100 A with a 22 kAIC rated main breaker. That 22K AIC figure matters if the utility transformer feeding the property can deliver high available fault current; a 10 kAIC unit would not be acceptable on that service.
5) Will this B-Line meter breaker pass a utility inspection on the West Coast?
It is EUSERC Approved, which is the specification most western US utilities require for metered service equipment, and it is UL listed. Always confirm the exact approved equipment list with your serving utility, since they publish their own accepted models.
6) How much wall space do I need for the 214 MTBH MS45 meter breaker, and how heavy is it?
Plan on 38 inches tall by 12 inches wide with a 4.63 inch depth off the wall. It weighs 35 lb, which is a two-person lift to hold in position while you set the mounting fasteners on a surface mount install.
7) Does this meter breaker have a bypass for pulling the meter under load?
It uses a test block for bypass rather than a lever bypass. That lets the utility connect test equipment and work the meter without dropping the service, but it is not the horn-style lever bypass some utilities specify. Check which style your utility requires before ordering.
8) How many meter positions does the 214 MTBH MS45 serve?
One. It's a single position meter breaker, so it covers one tenant or one service. For a duplex or a small multi-family building where each unit needs its own meter, you want a multi-position meter stack instead.
9) What kind of meter cover does this unit come with?
A ring type cover door, meaning the meter is secured with a sealing ring. Some utilities require ringless equipment, and the two are not interchangeable once the utility inspects, so verify the ring versus ringless requirement for your jurisdiction.
