Burndy BISR1DB – Frequently Asked Questions

1) Can this Burndy insulated splice connector be buried directly in the ground without a junction box?
Yes. The Burndy BISR series insulated screw-type splice is rated for direct burial, so it can be used for underground conductor splicing as well as above-ground work. The Plastisol insulation jacket is what seals the connection against moisture and environmental exposure.
2) What wire sizes does the Burndy BISR direct burial splice connector cover?
Three sizes are offered: 4 AWG (BISR4-DB), 3/0 AWG (BISR3/0DB), and a 1 AWG through 250 kcmil version (BISR1DB). Pick the one that matches the conductor you are splicing; the 1 AWG / 250 kcmil model covers the widest range of the three.
3) How many conductors can I land in one of these Burndy splices?
Two. The connector has 2 ports with 2 set screws, one screw per port, so it makes a single conductor-to-conductor splice. For a multi-tap or three-way connection you need a connector with more ports.
4) Is the Burndy BISR splice UL Listed for inspection sign-off?
UL Listed, and manufactured to UL468A-468B, the standards that cover splice and wire connectors. The materials are also RoHS compliant. It is not CSA certified, so on a Canadian job specifying CSA you will need a different connector.
5) Is a 600V splice connector enough for a commercial feeder run?
The BISR splice carries a minimum voltage rating of 600V, which covers standard commercial and industrial power distribution, feeder, and service entrance wiring. For anything in the medium-voltage class you need a different product family.
6) Do I need a crimp tool or dies for this connector?
No crimping gear is needed. This is a mechanical screw-type splice: strip the conductor, insert it in the port, and torque the set screw. That makes it a practical choice for field repairs and retrofit splices where a hydraulic crimper is not on the truck, versus a compression sleeve that requires matched dies.
7) Does the insulation on this splice mean I can skip taping the connection?
The BISR splice ships with a Plastisol insulation jacket over the body, so it is an insulated splice rather than a bare mechanical connector that has to be built up with tape or a mold. That jacket is the reason it holds a direct burial rating.
