B-LINE R10120 HDD – Frequently Asked Questions

1) Can the Eaton B-Line R10120 HDD bussed gutter be installed outdoors?
Yes. The R10120 HDD is built to NEMA Type 3R, so it is rated for outdoor use against rain and falling water. The enclosure is galvanized steel finished in ANSI 61 gray paint, and it is UL Listed.
2) What conductor sizes will land in the line lugs on this 600 A bussed gutter?
Line lugs on the R10120 HDD accept #4 through 600 MCM copper or aluminum range conductors, which covers most 600 A feeder sizing including parallel runs landed separately. Load connections are made on 5/16 inch mounting holes, so load lugs are bolted on to suit the tap you are running.
3) Is this B-Line termination cabinet suitable for a 3-phase 4-wire service?
Yes. The R10120 HDD is a 3-phase, 4-wire bussed gutter with a 600 A bus rating, so it will take a 3-phase 4-wire distribution including the neutral. It is not a single-phase-only product.
4) Will a 10 kAIC bussed gutter work on my service, or do I need a higher interrupting rating?
The R10120 HDD is rated 10 kAIC. If the available fault current at that point in the system exceeds 10,000 A, this cabinet is not the right choice and you need a higher-rated bussed gutter. On smaller commercial and multi-family services where the utility transformer keeps available fault current under 10 kA, it is within rating.
5) How much wall space do I need for the R10120 HDD gutter, and how is it mounted?
Plan for a surface-mounted run 120 inches wide and 28.5 inches high, projecting 6 inches from the wall. It is a surface mount unit, so the wall or structure behind it has to carry the load; the cabinet weighs 340 lb, which is a two-person plus lift job and needs backing into studs or masonry anchors, not drywall alone.
6) What is a bussed gutter used for, and when would I use one instead of a plain wireway?
A bussed gutter like the R10120 HDD carries factory-installed bus inside the enclosure so multiple feeders can be tapped off one 600 A source without a cabinet full of splice blocks. A plain wireway is only a raceway for conductors, no bus, no interrupting rating. Use a bussed gutter when you are distributing one service to several meters, panels, or tenant spaces and need a UL Listed, rated tap point; use a wireway when you are only routing and splicing conductors.
7) What cable sizes do the factory cable connections on this Eaton B-Line cabinet take?
The R10120 HDD is furnished with (2) 1/0-250 MCM cable connections, in addition to line lugs ranged #4 through 600 MCM. If your tap conductors fall outside 1/0-250 MCM you will need to specify load lugs to suit and bolt them to the 5/16 inch mounting holes provided.
