B-Line Eaton series bussed gutter and termination cabinets, 800 A, 3R, 10 kAIC, #4 - 600 MCM, 5/16" mounting holes for load lugs, Galvanized steel, 1Ø

Yes. The R1126 HE termination cabinet carries a NEMA Type 3R rating, which is the standard outdoor rain-tight classification for service equipment, and the enclosure is galvanized steel finished in ANSI 61 gray paint. It is a surface mount unit, so you need a wall or structure that will carry it, not a pad or free-standing frame.

Line lugs on the R1126 HE accept #4 through 600 MCM. The incoming service is landed as (2) 1/0-250 MCM cables, and the load side uses 5/16 inch mounting holes for load lugs, so your load lugs have to be drilled for a 5/16 inch stud pattern.

The R1126 HE is configured 1 phase / 3 wire, with three wires in the bussing. The bus is rated 800 A with a 10 kAIC short circuit interrupting rating, so it cannot be applied where available fault current at the terminals exceeds 10 kA.

Plan for an enclosure measuring 85.625 x 22 x 6 inches and weighing 195 lb. That is a long, shallow surface mount box, so the wall needs blocking or structural backing across most of its length, and it is a two-person set at minimum.

Aluminum bussing, inside a galvanized steel enclosure. If your spec or utility requires copper bus, this unit will not meet it. Aluminum bus also means the terminations need to be torqued to the lug markings and, where required by your inspector, treated with an approved antioxidant on aluminum conductors.

The R1126 HE is UL Listed. Bussed gutters and termination cabinets like this are used to take one large incoming feeder and split it to multiple loads without a separate distribution section, which keeps the tap connections in one accessible, rated enclosure.

A bussed gutter such as the R1126 HE is the right call when you need to tap one 800 A feeder out to several loads and do not need overcurrent devices in the same box. A plain wireway carries no bus and gives you nothing to land taps on. A distribution panelboard is what you want instead if each tap needs its own breaker. Note the 10 kAIC rating here, which is low for a service point with high available fault current.

Order Eaton B-Line model R1126 HE. That single model covers the 800 A, NEMA 3R, single phase configuration with #4-600 MCM line lugs and 5/16 inch load lug mounting holes, so there are no finish or size options to specify.
