B-Line 2012 MS60 Eaton series vertical meter pack, 100 A, 225 A, None, Ring type, 3R, Overhead/underground, ANSI 61 gray paint, 010 kAIC, #6 - 250 MCM, Galvanized steel, Surface mount, 4, 2, 3

Two meter positions, each on a 4-jaw socket wired for 3 wires. That configuration is single phase 3-wire service, so the 2012 MS60 suits a two-unit building, a duplex, or a pair of tenant spaces off one service. If you need more than two tenants metered, you need a larger position count than this pack carries.

Each meter socket is rated 100 A, and the bus feeding the pack is rated 225 A. That means two 100 A tenant services on a single 225 A main, which is the usual arrangement for a duplex or a small two-tenant commercial building. If your utility is setting a 200 A service per unit, this pack is undersized for the job.

Yes. It is a 3R enclosure, which is rated for outdoor use against falling rain, sleet, and ice formation, and the body is galvanized steel finished in ANSI 61 gray paint. It surface mounts, so it lands flat on the wall or on unistrut standoffs rather than recessing into the wall cavity. 3R is not washdown or hosedown rated, so keep it off a surface that gets pressure washed.

Either one. The 2012 MS60 is built for overhead or underground feed, so you do not have to order a different pack depending on which way the service drop or lateral arrives. Line lugs take #6 through 250 MCM, which covers the conductor range you would pull for a 225 A feed in copper or aluminum.

No bypass. Power has to be dropped to pull a meter on the 2012 MS60. Some utilities require a bypass on tenant metering so meters can be swapped without interrupting the unit, so check the utility's metering standard before you order this one. If bypass is required in your service area, you need a bypass-equipped pack instead.

Ring type. The meter is retained by a sealing ring rather than a ringless cover, and utilities are specific about which style they will accept on their meters. Confirm your utility accepts ring type sockets before ordering, because a ringless jurisdiction will reject this at inspection even though everything else about the pack is correct.

10 kAIC interrupting rating, and the pack is UL listed. Your available fault current at the service point has to be at or below 10 kAIC for this to be a code-compliant install. On a small 225 A service well down the utility transformer's secondary run that is usually fine, but on a building close to a large transformer it may not be, and your fault current study decides it.

Line lugs accept #6 through 250 MCM. That is a wide enough window for the service entrance conductors on a 225 A feed in either copper or aluminum. If your engineer has specified parallel runs or anything above 250 MCM, the lugs on this pack will not take it and you need a larger pack or a separate terminal box ahead of it.

Plan on 34 inches high by 22 inches wide, projecting 6 inches off the wall, plus the working clearance your inspector will want in front of it. It weighs 56 pounds, so it is a two-person lift onto the mounting hardware even though it is not a large enclosure. Surface mount means the full 6 inches sits proud of the finished wall, which matters on a walkway or a tight side yard.

The part number is 2012 MS60. It is an Eaton B-Line series vertical meter pack, galvanized steel in ANSI 61 gray paint. Quote it by that number when you are matching an existing bank of meters or ordering a replacement for the same configuration.

It is ANSI 61 gray paint over galvanized steel, which is the standard gray used across most utility and switchgear equipment, so it reads as a match next to existing service gear on a multi-family or commercial exterior. Only one finish is offered on this pack, so there is no alternate color to specify at order.
