Burndy YS25LBOX – Frequently Asked Questions

1) What size conductor does the Burndy YS25LBOX splice take?
The YS25LBOX HYLINK splice is sized for 1/0 AWG stranded copper, and it also covers 100 (61) Navy cable. It is a copper-to-copper splice only, so do not use it on aluminum conductors.
2) Which die do I set my crimper to for the Burndy YS25LBOX?
Die index is 12;99;348, and the connector carries a pink color code so you can match tool and die in the field. Set the correct die before crimping; the wrong die on a 1/0 splice is the usual cause of a failed pull test.
3) How much insulation do I strip back before crimping this 1/0 copper compression splice?
Strip 15/16 in of insulation from each conductor end. The splice is 2.08 in overall with a 0.88 in B length, so each conductor seats about half the barrel and the strip length lets the copper bottom out against the center stop.
4) Is the Burndy YS25LBOX UL Listed and CSA approved for 600V branch and feeder work?
Yes. It is UL Listed and CSA Approved to UL468A-468B, rated 600V minimum with a 35 kV maximum, so it covers standard 600V building distribution as well as medium voltage splicing up to that ceiling when used with the appropriate insulating system. RoHS compliance status is CM.
5) Does the tin plating on this Burndy splice matter for wet or underground locations?
The barrel is solid copper with an electro-deposited tin plating, which is what resists corrosion at the crimp in damp manholes, handholes, and direct-buried enclosures. Tin plating also keeps contact resistance stable over time. It does not make the splice submersible on its own; you still seal it with the tape or heat shrink system the job calls for.
6) Is a compression splice the right choice over a mechanical or split bolt connector for 1/0 copper?
A compression splice like the YS25LBOX makes a permanent, irreversible joint once crimped with the matching die, which is what you want for in-wall, buried, or enclosure splices that will never be reopened. Mechanical and split bolt connectors can be taken apart and retorqued, which suits accessible taps and temporary work. Choose compression where the splice gets covered up.
7) Is the Burndy YS25LBOX sold individually or only by the box?
Minimum pack quantity is 1, so you can buy a single YS25LBOX splice rather than a full carton. Useful for MRO stock where you only need a couple on the truck.
8) What does the chamfered barrel on this HYLINK splice do?
The barrel is a standard type with a chamfered mouth, which eases stranded 1/0 conductor entry so strands do not birdcage or fold back when you push the cable in. It is part of Burndy's HYLINK line.
