Burndy YA31L – Frequently Asked Questions

1) Will the Burndy YA31L lug take 350 kcmil copper cable?
That is exactly what the YA31L Hylug is sized for: 350 kcmil stranded copper, including 350 (91) Navy stranding. It is a copper-body lug, so it is for copper conductors only, not aluminum. The barrel is not adjustable, so a 250 or 400 kcmil cable needs a different catalog number.
2) What die index do I crimp the YA31L with?
Crimp with die index 18 (also referenced as 324 on some tooling charts). Strip the cable back 1-1/8 inches before inserting into the barrel. Using any other die on a 350 kcmil compression lug puts the connection outside its UL467 listing.
3) Will this lug bolt to a 1/2 inch stud on my switchgear bus?
Yes. The YA31L has one mounting hole drilled 0.52 inch (13 mm) for 1/2 inch bolt or stud hardware, with a straight tongue and a pad 1.29 inches wide. Check that your bus pad or breaker terminal has at least that much landing width and single-hole spacing before you commit.
4) Can I use this lug on medium-voltage cable, or is it 600V only?
The Hylug YA31L is rated per UL467 for use up to 35 kV, with a 600V minimum rating, at 90 degrees C. That covers 600V feeder work and medium-voltage terminations in switchgear and substation applications alike.
5) Is the YA31L suitable for grounding and bonding, or only power terminations?
UL467 is the grounding and bonding equipment standard, and the YA31L is listed to it for code conductor terminations. So it is used both for feeder and switchgear terminations and for grounding and bonding on 350 kcmil copper.
6) Is the YA31L a standard barrel lug or a long barrel?
Standard barrel, with skive-and-chamfer construction for a single crimp arrangement per the die index 18 spec. If your spec calls for a long barrel or two-hole pad, the YA31L is not the right catalog number; it is a one-hole, straight tongue, standard barrel lug.
7) Is the tin plating on this Burndy lug going to hold up in a damp or outdoor vault?
The body is solid copper with an electro-deposited tin plating, which is the standard corrosion-resistant finish for copper compression lugs in switchgear, substation and utility work. Tin plating also helps when landing on aluminum or plated bus. It is RoHS compliant.
8) What does the red color code on the YA31L mean?
Red is Burndy's Hylug color code for this conductor size, so an inspector or the next electrician can confirm at a glance that a 350 kcmil lug was used. It is an identification band only, not an insulating jacket rating.
9) Do I have to buy Burndy lugs in a box, or can I order one?
Minimum pack quantity on the YA31L is 1, so you can order a single lug for a repair or one-off termination rather than a full carton.
