Thomas & Betts ASL60-42 – Frequently Asked Questions

1) Can the Thomas & Betts ASL60-42 lug be used on copper conductors, or aluminum only?
Both. The ASL60-42 is a dual-rated mechanical lug, so it accepts copper or aluminum conductors. The body itself is aluminum with a tin-plated finish, which is what makes it acceptable on copper as well as aluminum and helps resist corrosion at the contact surface.
2) What wire range does the ASL60-42 take, and how many conductors?
The ASL60-42 is a four-conductor lug with a wire range of 2 STR through 600 (600 kcmil), per the manufacturer's designation AL 4CNDTR 2HOLE MOUNT 2STR-600. Each of the four ports is set-screw clamped, so you can land up to four runs on one pad.
3) How does the ASL60-42 mount to a bus bar or equipment pad?
It is a two-hole mount lug, so it bolts flat to a bus bar, panel pad, or transformer pad with two fasteners. Two-hole mounting stops the lug from rotating under torque when you tighten the conductor set screws, which is the usual reason a spec calls for it over a single-hole tongue.
4) Do I need a multi-port lug like the ASL60-42, or will a single-barrel lug do the job?
Use the four-port ASL60-42 when you have to land multiple feeders or taps on one equipment pad, such as a distribution panel or transformer terminal with more runs than lugs. If you are terminating a single conductor, a single-barrel lug is the simpler part, for example the Panduit Pan-Lug LAMA Series tin-plated aluminum mechanical lug. For two runs, a two-port lug such as the NSi 220T dual-rated set-screw connector covers it, and NSi's STL series goes to six ports for transformer work.
5) Will the ASL60-42 work for small branch-circuit wire like #12 or #14?
No. The ASL60-42 ports are built for 2 STR up to 600 kcmil, so small branch conductors are well below its range and will not clamp reliably. For fine wire, use a small lay-in lug instead, such as the Burndy CL501 Qiklug rated #14-4 AWG with a #10 stud.
6) What is the closest dual-rated aluminum mechanical lug to the Thomas & Betts ASL60-42?
The Burndy KA30U is the nearest equivalent in kind: it is a Type KA-U aluminum mechanical lug rated dual CU/AL, the same aluminum, dual-rated mechanical lug concept as the ASL60-42, which is an aluminum mechanical lug with a tin-plated finish. The ASL60-42 carries a 4-conductor body with a 2-hole mounting pad, so when you swap to the KA30U confirm the port count and mounting pattern you need, since the two are not the same configuration.
7) I only need to land one or two conductors - is there a smaller lug than the ASL60-42?
Yes. The ASL60-42 is built as a 4-conductor aluminum lug with a 2-hole mounting pad, which is more termination than a single feeder needs. For one or two runs, the NSi 220T is a dual-rated aluminum set-screw lug with two ports, and the NSi 300T is a single aluminum dual-rated set-screw lug. Both are dual-rated aluminum like the ASL60-42, just with fewer conductor openings.
8) What should I use instead of the ASL60-42 if I need more than four conductor ports?
Step up to a multi-port transformer lug. The NSi STL250-6 is a 6-port aluminum dual-rated transformer lug, so it takes two more conductors than the 4-conductor ASL60-42 while keeping the same aluminum, dual-rated construction. Verify the mounting pad drilling on the enclosure or transformer pad, since the ASL60-42 uses a 2-hole mount.
9) What else does ZenSupply carry as a dual-rated aluminum mechanical lug if the ASL60-42 is not the right size?
Burndy's Type KA-U aluminum mechanical lugs are dual-rated CU/AL in the same way, and NSi's T series aluminum set-screw lugs are also dual-rated. Those are single- and multi-port set-screw lugs you can size to your conductor. If your run is copper only and you want a copper body, the Burndy SCRULUG offset tongue copper mechanical lug is a different approach.
10) Is the Burndy CL501 Qiklug a substitute for the Thomas & Betts ASL60-42?
No. The CL501 is a Qiklug copper lay-in lug for #14 to #4 AWG that lands on a #10 stud - a small-wire, single-stud lay-in device. The ASL60-42 is an aluminum dual-rated mechanical lug with four conductor ports and a 2-hole mounting pad, intended for larger feeder terminations. They are not interchangeable in either direction.
11) If the conductors are copper only, should I pick a copper lug rather than the ASL60-42?
You can use either. The ASL60-42 is dual-rated, so it accepts copper as well as aluminum conductors. If you prefer a copper-bodied lug, the Burndy SCRULUG offset tongue mechanical lug is copper, and the Burndy CL501 Qiklug is a copper lay-in lug. The offset tongue on the SCRULUG also shifts the pad away from the barrel, which can help when the bus landing does not line up with the conductor entry - something the ASL60-42's 2-hole pad does not do.
12) How does the Panduit LAMA compare with the Thomas & Betts ASL60-42?
Both are tin-plated aluminum mechanical lugs. The Panduit Pan-Lug LAMA series is a single-barrel lug, meaning one conductor per lug, while the ASL60-42 is a 4-conductor body on a single 2-hole mounting pad. Choose the LAMA when each conductor gets its own landing and the ASL60-42 when you want four runs consolidated under one pad.
13) My panel has limited width for the lug pad - what is an alternative to the ASL60-42?
Look at a stacked-port design. The NSi 350T-2 is a 2-port stacked aluminum alloy lug connector, which arranges the conductor ports vertically instead of spreading them across the pad the way the 4-conductor ASL60-42 does. It lands fewer conductors, so for four runs in a tight enclosure you may need two of them.
14) Is the ASL60-42 sold individually or in a pack?
Each. The ASL60-42 is sold as a single connector, so order one per termination point you need to make.
15) Is the ASL60-42 suitable for outdoor or damp electrical gear?
The aluminum body carries a tin plating, which is there for corrosion protection and a stable contact surface. That makes it a reasonable choice in distribution equipment and industrial panels where humidity and dissimilar-metal corrosion are a concern. Enclosure rating is a function of the gear it goes into, not the lug.
