B-Line Eaton series single meter sockets, 200 A, 4 jaws, ANSI 61 gray coat, Aluminum

A 4-jaw socket is the single-phase, 3-wire configuration used on ordinary 120/240V residential and light commercial services. The Eaton B-Line U204 F MSCD is rated 200 A with 4 jaws. If your utility requires a 5-jaw socket (network or 120/208V single-phase off a three-phase system), this one will not satisfy that, and if you are metering a three-phase service you need a 7-jaw socket instead.

Plan for an enclosure 15 inches high by 8 inches wide, standing 4.62 inches off the wall. That depth matters on a narrow exterior wall or inside a recessed meter alcove, and the 8 inch width lets it sit alongside a disconnect or panel without much clearance loss. It weighs 15 lb, so one person can set it, but anchor into studs or use masonry anchors on block.

The Eaton B-Line U204 F MSCD single meter socket is UL Listed. Most utilities also maintain their own approved-socket list by catalog number, so match the U204 F MSCD designation against your serving utility's list before the meter set.

The enclosure is aluminum with an ANSI 61 gray painted finish. Aluminum does not rust the way painted steel does once the coating is scratched, which is why it gets specified on exterior service equipment. In salt air, keep the paint intact and use stainless or coated fasteners so you are not setting up a dissimilar-metal problem at the mounting points.

No. This is a single meter socket, one meter position only. For a two-unit building you would either set two individual sockets or use a multi-position meter stack or gang socket rated for the number of tenants. Ordering singles for a six-unit building means six separate enclosures, six sets of taps, and a lot more wall.

Order by catalog number U204 F MSCD. That is the Eaton B-Line single-position socket, 200 A, 4 jaws, aluminum enclosure, ANSI 61 gray. Give that number to the utility inspector as well, since socket approvals are tracked by catalog number.

ANSI 61 gray is the standard light gray used across most commercial electrical enclosures, so the socket will read as the same color family as typical panelboards, disconnects and wireways rather than a mismatched piece on the wall. Useful when a property manager is standardizing the look of a meter bank across buildings.
