Burndy YA1CLBOX – Frequently Asked Questions

1) What wire sizes does the Burndy HYLUG 1-hole copper compression lug come in?
Two conductor sizes are offered on the tin-plated HYLUG one-hole copper lug: 1 AWG, ordered as YA1CLBOX, and 750 kcmil, ordered as YA39L. Both are copper barrel, compression type, so pick the part that matches the conductor you are terminating rather than trying to crimp an oversize barrel down.
2) Will the Burndy YA1CLBOX lug bolt onto a 5/16 inch stud in my panelboard?
Yes. The YA1CLBOX has a single mounting hole drilled 0.33 inch (8 mm), which is the clearance size for a 5/16 inch stud or bolt. Pad width is 0.68 inch, so check your busbar or neutral bar spacing if you are landing several lugs side by side.
3) Is this Burndy compression lug rated for medium voltage work or only 600V?
Rated 600V minimum and good up to 35,000V (35 kV), so the HYLUG copper compression terminal covers both standard 600V building distribution and medium-voltage terminations. It is UL Listed and CSA Approved.
4) Can I use this tin-plated copper lug on an aluminum conductor?
No. This is a copper barrel lug specified for copper conductors, so an aluminum or compact aluminum cable needs a lug rated for aluminum (or a dual-rated AL9CU type) instead. The electro-tin plating here is for corrosion resistance on the copper body and at the bolted pad, not a substitute for aluminum rating.
5) How much insulation do I strip back before crimping this Burndy copper lug?
Strip length on the YA1CLBOX is 15/16 inch. The barrel is chamfered, which makes pushing the stranded conductor in easier, and overall length of the lug is 1.94 inch (49 mm) with a 0.46 inch barrel outside diameter, worth knowing when you are working in a tight gutter.
6) Why choose a compression lug over a mechanical set-screw lug for a service termination?
Compression is a permanent, die-crimped connection: once the barrel is crimped with the matching Burndy die there is no screw torque to lose over thermal cycling, which is why these are used on switchgear, panelboard and grounding terminations. A mechanical set-screw lug is the choice when you need to re-terminate or cannot get a crimp tool into the space. This HYLUG is compression only.
7) Can this Burndy HYLUG be used for a grounding electrode or bonding connection?
Yes, grounding and bonding connections are among its listed applications, along with code conductor terminations, panelboard and switchgear wiring, and utility power distribution. It is a copper compression lug, so it suits copper grounding conductors of the matching size (1 AWG or 750 kcmil).
8) Do I have to buy these Burndy lugs by the box or can I order a single?
Minimum pack quantity is 1, so you can order one lug for a single termination or repair rather than committing to a full carton.
