B-LINE 227 MTBH MS45 – Frequently Asked Questions
1) Will the B-Line 227 MTBH MS45 meter breaker work on a three-phase four-wire service?
Yes. The 227 MTBH MS45 is built for 3-phase, 4-wire service and uses a 7-jaw meter socket, which is the standard socket configuration for that service type. It is a single-position unit, so it serves one meter.
2) Can this Eaton B-Line meter breaker be mounted outdoors?
Yes. The 227 MTBH MS45 enclosure is 3R rated, so it is suited to outdoor rain and sleet exposure, and it is finished in ANSI 61 gray paint over steel. It surface mounts to a wall or structure rather than recessing into it.
3) What size conductors will land in the line lugs on the 227 MTBH MS45?
Line lugs accept #6 through 250 MCM, which covers most 200 A copper and aluminum service entrance conductors. The unit is rated 200 A. Load side terminates at the main circuit breaker.
4) Is the interrupting rating high enough for a 22 kAIC available fault current requirement?
It is. The main breaker in the 227 MTBH MS45 is rated 22 kAIC, so it meets a 22,000 A available fault current spec at the service point. Anything above that calls for a higher AIC assembly.
5) Will the utility accept this meter breaker for a new service installation?
The 227 MTBH MS45 is EUSERC Approved, which is what most western US utilities require on service equipment submittals, and it is UL certified. It comes with a ring-type cover door for the meter.
6) How much wall space and clearance do I need for this 200 A meter breaker, and can one person set it?
Plan on a footprint of 48 inches high by 14 inches wide with a 6 inch depth off the wall. It weighs 56 pounds, so it is a two-person lift to hold in position while the mounting fasteners go in.
7) Does this meter breaker have a bypass for meter changes without dropping the load?
It is furnished with a test block rather than a lever or horn bypass. That lets the utility test and change the meter through the test block provisions. If your utility mandates a lever bypass, specify a lever bypass model instead.
8) What exactly is the part number to order for this Eaton B-Line meter breaker?
Order it as B-Line 227 MTBH MS45. That single designation covers the 200 A, 7-jaw, 3-phase 4-wire, 3R surface mount assembly with test block bypass; there are no finish or size options to pick.
