B-Line Eaton series vertical meter pack, 100 A, 225 A, None, Ring type, 3R, Overhead/underground, ANSI 61 gray paint, 010 kAIC, #6 - 250 MCM, Galvaniz

Three meter positions, each a 4-jaw, 3-wire ring-type socket rated 100 A. That covers a single-phase 3-wire service per tenant, so it suits a triplex or a three-unit commercial building on one service. Four jaws and three wires means single-phase only, not a 3-phase 4-wire tenant load.

Yes. The enclosure is 3R rated, which is the standard rain-tight outdoor rating for wall-mounted service equipment, and it is galvanized steel finished in ANSI 61 gray paint. It is surface mount, so it bolts to the wall face rather than recessing into the stud cavity.

The line lugs take #6 through 250 MCM. That range covers aluminum or copper service entrance conductors for a main up to 225 A, and it is landed the same whether you come in from overhead or underground, since the pack is built for either feed.

The interrupting rating here is 10 kAIC. That is adequate where the available fault current at the service point is 10,000 A or less, which is typical of small residential and light commercial services fed from a modest utility transformer. If the utility's fault current letter comes back above 10 kA, this pack is not the right choice and you need a higher-AIC assembly.

No bypass. Power has to be dropped at the service to pull or change a meter on this unit. If your utility requires lever or horn bypass on multi-meter equipment, specify a bypass version instead. Some utilities mandate it for anything over a certain amperage, so check the local service handbook before ordering.

Plan on 39.5 x 22 x 6 inches. The 6 inch depth is the projection off the wall for surface mounting, and at 63 lb it wants two people and blocking or masonry anchors behind it. Leave the NEC working clearance in front of the meter faces.

Ring type means the meter is held by a sealing ring clamped around the meter rim, rather than a hinged ringless cover that traps the meter behind it. Utilities specify one or the other, and they are not interchangeable in the field, so confirm your serving utility calls for ring type before ordering this 2013 MS60 pack.

It carries a UL certification. Combined with the 3R enclosure and the 225 A bus with 100 A meter positions, that is what a plans examiner or utility inspector looks for on multi-family service equipment.

Either one. The pack is built for overhead or underground feed, so it works with a service mast and drop or with a lateral coming up from a trench, and the same #6 to 250 MCM lugs land the conductors in both cases.

Order it as B-Line 2013 MS60. That single model covers the 3-position, 100 A, 4-jaw, 3-wire, ring-type, NEMA 3R configuration with no bypass.
