B-LINE LK4R9DL – Frequently Asked Questions
1) Does the LK4R9DL lug kit cover both the line and load side of a rotary disconnect?
No. One LK4R9DL kit covers one side only, line or load. If you need lugs on both the incoming and outgoing side of the disconnect, order two kits. Each kit contains 4 lugs, which is why it suits a four-pole switch.
2) What wire size can I land in the B-Line LK4R9DL terminal lugs?
Each phase accepts #6 through 300 kcmil conductor. The lugs are rated for both copper and aluminum cable, so you can land Cu or Al feeders without a separate lug kit.
3) Will these lugs fit my Eaton rotary disconnect switch?
The LK4R9DL is built for Eaton R9 series rotary disconnects in the D-frame size, covering switches rated 100 to 200A. If your disconnect is a different frame size or outside that amp range, this is not the right lug kit.
4) Is the LK4R9DL a four-pole lug kit or will it work on a three-pole disconnect?
It is a four-pole kit, supplied with 4 lugs. On a three-pole switch you would have a spare lug, which some installers use for a switched neutral if the disconnect is built for it. For a straight three-pole job, order the three-pole kit for the D-frame R9 instead.
5) Can I use aluminum feeder cable with the LK4R9DL, or do I need copper?
Either. These are Cu/Al rated lugs, so aluminum or copper conductor from #6 up to 300 kcmil per phase lands in the same terminal. That matters on larger services where aluminum is the cheaper pull.
6) What is the exact part number to order for four-pole D-frame R9 disconnect lugs?
Order Eaton B-Line LK4R9DL. That is the four-pole, D-frame, 100 to 200A lug set for R9 rotary disconnects, one set per side.
7) How much room do I need in the enclosure for these disconnect lugs?
Each lug measures 1.52 inches long, 1.2 inches high and 1 inch wide, and the kit weighs 1.43 lb. Lay that out against your gutter space before you pull 300 kcmil in, since bending radius on the larger conductors usually drives the enclosure size more than the lug body does.
