Burndy YA1CA1 – Frequently Asked Questions
1) Can I use the Burndy YA1CA1 lug on aluminum and copper conductors?
The Burndy HYLUG YA1CA1 is dual rated for both aluminum and copper conductors, sized at 1 AWG stranded either way. That means one lug covers an aluminum feeder termination or a copper one, so you don't need to stock two part numbers for the same size. It ships prefilled with PENETROX oxide inhibiting compound, which is what makes the aluminum side of that rating work in service.
2) What die index do I set my crimper to for the Burndy YA1CA1?
Die index 471, gold color code. The lug is marked with the wire size and the color code so the crew can confirm the die on the job without hunting for a chart. Crimp it with a tool that accepts Burndy index dies, and match 471 exactly, an undersized or oversized die is the usual cause of a failed pull test on a compression lug.
3) Will this 1 AWG lug bolt to a 3/8 inch stud on my switchgear bus?
Yes. One tongue hole sized for a 3/8 inch stud, with the hole measuring 0.44 in (11 mm) and a straight, standard tongue. The pad is 0.76 in wide, so check your bus spacing if you are landing several lugs side by side on the same pad.
4) How much insulation do I strip back for this Burndy compression terminal?
Strip 15/16 in of insulation. Barrel length is 0.91 in and the barrel is internally bevelled, so the conductor feeds in without birdcaging as long as the strip is clean and square. Bottom the conductor in the barrel before crimping.
5) Is the Burndy YA1CA1 rated for 90 degree C conductors and medium voltage circuits?
It carries a 194 F temperature rating (90 C) and is UL Listed to UL468A-468B. Voltage rating runs from 600 V up to 35 kV, which covers both low voltage panel work and medium voltage terminations such as substation and switchgear connections.
6) Can I use the YA1CA1 on 2 AWG or 1/0 cable?
No. This lug is built for 1 AWG stranded only, aluminum or copper, and the barrel is sized to that conductor. Crimping a smaller or larger conductor in it will not give you a compliant connection. For other sizes, order the matching YA-A HYLUG for that AWG with the 3/8 inch stud hole you need.
7) Does this lug have an inspection window?
No, the YA1CA1 is a one hole aluminum compression lug without an inspection window. The barrel is a standard closed type, so you verify the conductor is fully bottomed before you crimp rather than looking through the barrel afterward. If your inspector requires a visible conductor, you need a window version instead.
8) What are the overall dimensions of the Burndy YA1CA1 lug for a tight enclosure?
Overall length is 2.59 in (66 mm), barrel outside diameter 0.54 in, pad width 0.76 in, and the hole center sits 0.75 in from the tongue end. Useful when you are checking bend radius and clearance in a shallow gutter or a crowded pull box.
9) Is a compression lug the right choice, or should I use a mechanical set screw lug?
A compression terminal like the HYLUG YA-A is crimped with a die (index 471 here) and is the type specified where the connection has to stay tight under vibration and thermal cycling, and where an inspector wants a permanent, non adjustable termination. Mechanical set screw lugs are quicker with no tooling and are re-enterable, which suits service work and field changes. If you don't own or can't rent a crimper that takes Burndy index dies, a mechanical lug is the practical call.
10) Will the tin plating hold up in a damp or corrosive plant environment?
The body is high conductivity wrought aluminum with electro-tin plating, which is what gives it corrosion resistance and lets it land on copper or plated bus without a dissimilar metal problem at the pad. Combined with the factory PENETROX in the barrel, both ends of the connection are protected. It is also RoHS compliant.
