Burndy YS28LBOX – Frequently Asked Questions

1) What conductor size does the Burndy YS28LBOX splice take?
The YS28LBOX HYLINK splice is sized for 4/0 AWG stranded copper, and it carries the 200 (61) Navy size reference for shipboard and government work. It is a copper-to-copper splice only, so do not use it on aluminum conductors.
2) Which compression die do I use to crimp the YS28LBOX?
Die index 15, purple color code. Match the purple die marking on your Burndy hydraulic or battery crimper head to the purple band on the splice and you have the right die. Getting the index right is what makes the crimp hold, so check the tool die table before the first crimp of the day.
3) How much cable do I strip for a Burndy 4/0 copper compression splice?
Strip 1-1/16 inches of insulation from each conductor end. The barrel's B length (the depth each conductor seats to) is 1 inch, and overall the splice is 2.32 inches long, so the extra sixteenth gives you the clearance to bottom the conductor without forcing insulation into the barrel.
4) What voltage is the Burndy YS28LBOX HYLINK splice rated for?
Minimum rating is 600V and the maximum is 35 kV, so the same splice covers 600V building feeders and medium-voltage distribution cable up to 35,000 volts. On MV cable the splice itself is only the conductor connection, you still build the insulation and shield system around it with the appropriate splice kit.
5) Is the Burndy YS28LBOX UL Listed and CSA approved?
Yes on both. It is UL Listed to UL468A-468B and CSA Approved. Note it is not ETL certified, not cULus marked, and not UL Recognized, it is a full UL Listing. RoHS compliance status is CM.
6) Can this copper splice be used in a damp or buried location?
The body is copper with an electro-deposited tin plating for corrosion resistance, which is the standard finish for direct-buried and underground distribution splicing as well as overhead work. In wet or buried service, pair it with an oxide-inhibiting compound and the sealing system your splice kit calls for, the plating protects the connector but does not seal the joint.
7) What does the chamfered standard barrel on this Burndy splice do for installation?
The chamfer at the barrel mouth lets the stranded conductor enter without birdcaging or shaving strands off on the lip, which matters on 4/0 with 61 strands. It is a standard barrel type, meaning a single continuous compression barrel rather than a stepped or reducing design, so both ends take the same 4/0 copper and the same die index 15 crimp.
8) Is the YS28LBOX sold individually or only in a full box?
Minimum pack quantity is 1, so you can order a single splice rather than a full carton. That suits a one-off repair; for a crew running a distribution job, order per splice count plus spares, since a miscrimped barrel is cut out and replaced, not re-crimped.
