B-Line 174 HSHDB Eaton series horizontal meter pack, 100 A, 225 A, Ring type, 3R, Overhead/underground, ANSI 61 gray paint, #6 - 250 MCM, #14 - 2/0, Galvanized steel, Surface mount, 4, 4, 3

The 174 HSHDB horizontal meter pack carries 4 metering positions, each with a 4-jaw, 3-wire socket. That configuration suits a single-phase 3-wire (120/240V) service feeding four tenants, so it fits a four-unit apartment building, a small strip of retail bays, or a four-unit addition where each occupant is billed separately. If you need more or fewer than four positions, you need a different pack in the series.

Yes. The enclosure is rated 3R, which is the standard outdoor rain-and-sleet rating for service equipment, and it is galvanized steel finished in ANSI 61 gray paint. It surface mounts to a wall. It is not rated for washdown or dust-tight locations, so it belongs on an exterior wall or in a service room, not in a hosed-down or heavily dust-laden space.

Line side lugs take #6 through 250 MCM, so the incoming service conductors can run up to 250 MCM copper or aluminum. Load side lugs are smaller, #14 through 2/0, which covers the tenant feeders out of each position. Check your conductor size against both ends before you order: a load feeder larger than 2/0 will not land in these lugs.

Ring type. The meter is held by a sealing ring rather than a ringless cover, so confirm your utility accepts ring type sockets in your area before ordering. Utilities standardize on one or the other and will refuse to set a meter on the wrong style.

No bypass is provided. Power has to be dropped to pull or set a meter, which means a planned outage for that tenant. If your utility or facility requires hot-socket bypass for meter changes, you need a bypass-equipped pack instead of this one.

Each metering position is rated 100 A, which is the typical service size for an individual apartment or small commercial tenant. If any single tenant needs more than 100 A, that unit has to be metered on a larger socket rather than dropped into this pack.

Either one. The 174 HSHDB is built for overhead/underground feed, so the same pack can be fed from a mast and weatherhead or from a lateral coming up from below. That matters on a retrofit where the utility is converting a building from overhead to underground, since the meter pack does not have to change.

It measures 48 inches wide, 12 inches high, 4.63 inches deep, and weighs 42 pounds. The horizontal layout means you need a clear 4-foot run of wall rather than a tall vertical space, and the shallow 4.63 inch depth keeps it tight to the wall. At 42 pounds it is a two-person lift for accurate mounting, and the wall needs solid blocking or masonry anchors across the full 48 inches.

The 174 HSHDB carries UL certification, which is what an inspector looks for on multi-metering service equipment. Pair that with the 3R enclosure rating when you submit it against an outdoor service location on the drawings.

Order it as 174 HSHDB, Eaton B-Line series. That designation covers the 4-position, 4-jaw, 3-wire horizontal pack rated 100 A per position with a 225 A bus, ring type cover, 3R galvanized steel enclosure in ANSI 61 gray.
