Burndy YA1CL2 – Frequently Asked Questions

1) Which stud sizes does the Burndy YA1CL HYLUG lug come in for 1 AWG copper?
Two stud sizes are offered: the YA1CL2 for a 1/4 inch stud and the YA1CL6BOX for a 1/2 inch stud. Both are one-hole, straight tongue copper compression lugs for 1 AWG copper conductors, so pick the one that matches the bolt or stud diameter on your bus bar or breaker pad.
2) How much insulation do I strip off the 1 AWG conductor before crimping this lug?
Strip 15/16 inch of insulation. That matches the barrel depth on the YA1CL, whose B length (barrel) is 7/8 inch, so the conductor bottoms out in the barrel with the strip fully seated. The barrel outside diameter is 0.46 inch if you need to check clearance in a crowded gutter.
3) What die do I set my hydraulic crimper to for the Burndy YA1CL?
Die index 11 (also called 375) is the correct crimp for this lug. It is a compression termination, not a set screw or mechanical lug, so it has to be crimped with the matching Burndy die and tool. Using an off-index die voids the connection's UL listing.
4) Is the Burndy YA1CL rated for grounding and bonding per code?
Yes. The HYLUG YA1CL is UL Listed, CSA Approved, and built to UL467, which is the grounding and bonding equipment standard, and it is specified for code conductor use. That makes it acceptable for grounding electrode and bonding jumper terminations as well as general power connections.
5) Can I use a copper compression lug on aluminum conductor?
No. This HYLUG is a solid copper body sized for copper conductor only. Aluminum needs an aluminum or dual-rated AL9CU connector with the proper inhibitor compound; putting aluminum into a copper-only barrel creates a dissimilar metal joint that will corrode and loosen.
6) Will a 1 AWG lug like this work on fine-stranded welding or DLO cable?
No. The YA1CL barrel is sized for 1 AWG code (Class B) copper conductor, and it also covers 75 (37) strand Navy copper. Flexible welding cable, DLO, or other fine-stranded 1 AWG has a larger overall strand bundle and needs a flex-rated lug with a matching die. Crimping it into a code-conductor barrel gives you an out of spec connection.
7) What voltage can I use the Burndy YA1CL copper lug at?
600V is the minimum rating and the voltage class runs to 35 kV (35,000V), so the same lug covers low voltage panel work and medium voltage terminations up to 35 kV. On the medium voltage side the insulation system, not the lug, is what limits you.
8) Will the 1/4 inch stud version bolt to a 1/4 inch bus bar hole?
Yes. The YA1CL2 has a single 0.27 inch mounting hole, which clears a 1/4 inch bolt or stud with normal tolerance. Tongue width across the pad is 0.68 inch and overall length is 1.81 inch, so check you have that much flat pad area and barrel run before committing in a tight enclosure.
9) Does the tin plating on this Burndy lug matter for outdoor or industrial panels?
It does. The copper body is electro tin plated, which slows oxidation and corrosion at the contact face, so the joint keeps its resistance in damp, salty, or chemically aggressive industrial spaces. Tin plating also makes the lug a cleaner match against tin or plated bus pads than bare copper.
10) How do I identify the right Burndy HYLUG size on the job, and can I buy just one?
HYLUG lugs are color coded by conductor size, and 1 AWG carries the green code, so a green band on the barrel is your field check that you have the right one before crimping. Minimum pack quantity is 1, so you can take a single piece for a one-off termination rather than a full box.
