B-LINE 1M1R – Frequently Asked Questions

1) Will the B-Line 1M1R meter breaker work on a single-family 120/240V service?
Yes. The 1M1R is a single meter position, single-phase unit rated 120/240 V with a 100 A rating, which is the standard residential service configuration. It ships with one 100 A 2-pole main circuit breaker built in, so it serves as both the meter socket and the service disconnect.
2) Can the 1M1R meter breaker be mounted outdoors on an exterior wall?
It's a NEMA 3R enclosure built for outdoor surface mounting, in galvanized steel with an ANSI 61 gray painted finish. It's configured for overhead service entry with an AW hub, so the service drop comes in from above rather than underground.
3) What size conductors will land in the B-Line 1M1R?
Lug range on the 1M1R is #14 through 2/0, with aluminum bus. That covers a typical 100 A copper or aluminum service entrance conductor set. Check your conductor material and the local derating before sizing.
4) Does the 1M1R meter breaker take a ringless or ring-type meter cover?
Ring type. The 1M1R uses a ring-style meter socket with 4 jaws and 3 wires. Many utilities specify one style or the other, so if your serving utility requires ringless, this is not the unit for that opening.
5) Is the 1M1R utility-approved and UL listed?
The 1M1R carries a UL certification and is EUSERC approved, which is the approval most western US utilities look for on metering equipment.
6) Do I still need a separate main breaker panel with the 1M1R?
No separate service disconnect is needed. The 1M1R combines the meter socket with a 100 A 2-pole main circuit breaker, so it acts as the service disconnecting means at the meter. You still run feeders from it to a downstream load center for branch circuits, and that panel is a main-lug unit rather than another main breaker panel.
7) Is a 10 kAIC interrupting rating enough for my service?
The 1M1R main breaker is rated 10 kAIC. That's adequate where the available fault current at the service point is 10,000 A or less, which covers most residential and light commercial 100 A overhead services. If the utility transformer is large or close, get the available fault current letter from them first, because a higher AIC unit would be required.
8) How much wall space do I need for the 1M1R meter breaker?
The enclosure measures 24 in high by 8 in wide with a depth of 4.625 in, and it weighs 16 lb, so it's a one-person set on a stud or block wall. Leave the required working clearance in front of the disconnect.
