B-LINE 1M1R7 – Frequently Asked Questions

1) Is the B-Line 1M1R7 meter breaker rated for outdoor mounting?
Yes. The 1M1R7 is a 3R enclosure, so it is built for outdoor surface mounting on the side of a building. The housing is galvanized steel finished in ANSI 61 gray paint, which is the standard utility gray you see on service equipment.
2) What size wire will the 1M1R7 meter socket terminals take?
Line and load terminations accept #14 through 1/0 conductors, which covers a typical 100 A residential or small commercial service run in either copper or aluminum. The internal bus is aluminum.
3) Does this Eaton B-Line meter main come with the main breaker installed, or do I buy it separately?
The main breaker is included: one 100 A, 3-pole main circuit breaker in the same enclosure as the meter socket. That is what makes it a meter-breaker rather than a plain meter socket, so you are not sourcing a separate service disconnect.
4) Is the 1M1R7 a ringless or ring-type meter socket?
Ring type. Utilities differ on which they will accept, and a ring-type socket needs a sealing ring at the meter, so check the serving utility's spec before you set it. It is a single meter position unit with 7 jaws.
5) Can I use this for an underground service lateral?
No. The 1M1R7 is configured for overhead service, and it ships with an AW hub on top for the service entrance conductors. For an underground lateral you want a bottom-feed unit without the overhead hub.
6) Will a 10 kAIC meter main be enough for my service?
The 1M1R7 is rated 10 kAIC at 120/240 V. That is adequate where the available fault current at the service point is 10,000 A or less, which covers most single-family and light commercial drops. If the utility's transformer calculation puts available fault current above 10 kA, you need higher-rated service equipment.
7) Is the Eaton B-Line 1M1R7 UL listed and EUSERC approved?
Both. It carries UL certification and is EUSERC approved, which matters on the western US utilities that require EUSERC-compliant service equipment before they will set a meter.
8) How much wall space does the 1M1R7 meter breaker need?
Plan for a footprint of 24 in high by 8 in wide, with 4.625 in of depth off the wall. It weighs 17 lb, so one person can set it, but leave the code-required working clearance in front of the meter and disconnect.
9) Is this a combination meter socket and load center with branch breaker spaces?
No. The 1M1R7 combines a single-position meter socket with a 100 A main breaker only, with no branch circuit spaces. Feed a separate panelboard downstream of the main for your branch circuits.
