B-LINE R1125 HEE – Frequently Asked Questions

1) Can the B-Line R1125 HEE bussed gutter be mounted outdoors?
Yes. The R1125 HEE termination cabinet is a NEMA type 3R enclosure, which is rain and sleet resistant for outdoor surface mounting. It is galvanized steel with ANSI 61 gray paint, and it surface mounts, so you need a wall or structural backing rather than a floor pad or flush pocket.
2) What size feeder conductors will the line lugs on this 800 A bussed gutter accept?
Line lugs on the R1125 HEE take conductors from #4 through 600 MCM, so a typical 800 A parallel feeder set lands without adapters. It is a 3-phase, 4-wire bussed gutter rated 800 A. The load side uses 5/16 inch mounting holes for load lugs, meaning load lugs bolt on and are selected to match the tap conductors you are running.
3) Is a 10 kAIC bussed gutter enough for my service, or do I need a higher rated cabinet?
The R1125 HEE is rated 10 kAIC, so it can only be applied where the available fault current at that point in the system is 10,000 A or less. On a large utility transformer or close to the service, available fault current commonly exceeds that, and a higher short circuit rated termination cabinet is required. Have the fault current calculated at the cabinet location before committing.
4) How much wall space and support do I need for the R1125 HEE termination cabinet?
Plan for an enclosure measuring 71.25 inches wide by 28.5 inches high with a 6 inch depth, weighing 197 lb. At that weight and width it is a two-person set on unistrut or structural backing, not drywall anchors, and the shallow 6 inch depth keeps it tight to the wall in a corridor or exterior wall run.
5) What do I still have to order to finish an installation with this bussed gutter?
The load side of the R1125 HEE is drilled with 5/16 inch mounting holes for load lugs, so the load lugs themselves are chosen and ordered to match the tap conductor sizes on your job. Line side lugs cover #4 through 600 MCM. Mounting hardware for the wall or strut, plus conduit fittings into the enclosure, are job-supplied.
6) Is this bussed gutter UL Listed for use on a commercial service?
Yes, the R1125 HEE bussed gutter and termination cabinet is UL Listed. Ratings an inspector will look for are 800 A bus, 10 kAIC short circuit, 3-phase 4-wire, and a NEMA 3R enclosure.
7) Is the bussing in this cabinet copper or aluminum, and does that affect my terminations?
Bussing in the R1125 HEE is aluminum, in a galvanized steel enclosure. With aluminum bus, use listed lugs and an approved joint compound where required, and torque connections to the lug manufacturer's values. If your specification calls out copper bus, this cabinet does not meet it.
8) Will this work for a single-phase 3-wire service?
No. The R1125 HEE is bussed for 3-phase, 4-wire service. For a single-phase 3-wire application you want a termination cabinet bussed for that configuration instead; using a 3-phase 4-wire cabinet leaves a bus unused and may not match the drawing or the inspector's expectation.
9) How many cables per phase does this termination cabinet handle on the tap side?
The cabinet is configured for (2) 1/0-250 MCM cables, which is what you land per tap position on the R1125 HEE. Incoming line lugs accept #4 through 600 MCM.
10) What is the exact part number to order for the 800 A 3R B-Line bussed gutter?
Order Eaton B-Line model R1125 HEE. That covers the 800 A, 3-phase 4-wire, NEMA 3R galvanized steel cabinet with aluminum bussing and a 10 kAIC rating.
