B-Line 154 MCCM Eaton series horizontal meter pack, 100 A, 225 A, Manual circuit closing, Ring type, 3R, Overhead/underground, ANSI 61 gray paint, 010 kAIC, #6 - 250 MCM, Galvanized steel, Surface mount, 4, 4, 3

The Eaton B-Line 154 MCCM horizontal meter pack carries four meter positions, each with a 4-jaw, 3-wire socket rated 100 A. That 4-jaw/3-wire arrangement is single phase 120/240 V service, so it suits a four-unit building on individual metering. It is not a 5-jaw 4-wire configuration, so do not spec it for three phase tenant loads.

Yes. The enclosure is rated 3R, which is rainproof outdoor service, and it is galvanized steel finished in ANSI 61 gray paint. It is a surface mount unit, so it bolts to the wall face rather than recessing into it. Plan the wall for the load: it measures 43 in wide, 28.5 in high, 4.63 in deep and weighs 82 lb empty.

The main line lugs accept #6 through 250 MCM, which covers the usual copper and aluminum service entrance conductors for a 225 A main. If your service conductors are larger than 250 MCM, this stack will not terminate them without reducers or a separate tap box.

The 154 MCCM is rated 010 kAIC and carries UL listing. 10 kAIC is adequate where the available fault current at the meter pack is 10,000 A or less. On a service fed by a large utility transformer with short conductors the calculated fault current can exceed that, and in that case you need a higher AIC assembly. Get the utility's available fault current at the point of connection before you commit.

They describe different things. Each of the four meter positions is rated 100 A, while 225 A is the rating of the bus and main line side of the assembly. So the stack handles up to a 225 A service feeding four 100 A tenant positions. Don't read the 225 A as a per-unit capacity.

Either. The 154 MCCM is built for overhead or underground feed, so the same unit can be used behind a service mast or fed from a lateral, which is useful when you are standardizing hardware across buildings served differently.

Manual circuit closing bypass. A meter technician closes the bypass by hand before pulling the meter, keeping the tenant energized during the swap. That is the utility-preferred setup where meters are changed hot; if your utility requires automatic bypass, this is not the right unit.

Yes, the meter sockets are ring type, so they take the sealing ring the utility installs around the meter. If your utility only sets ringless meters with a hinged socket cover, specify a ringless version instead.

Order it as Eaton B-Line 154 MCCM. That number carries the whole configuration: horizontal 4-position, 4-jaw 3-wire, 100 A sockets on a 225 A bus, ring type, 3R, manual circuit closing bypass.
