Blackburn KL57-1 – Frequently Asked Questions
1) What conductor sizes does the Blackburn KL57-1 service entrance splice take?
The KL57-1 is a reducing splice: the A side takes 4/0 and the B side takes 2/0. It joins two conductors, one per end, so it is for a single run-to-run transition, not a multi-tap block.
2) Is the KL57-1 splice insulated, or do I need to cover it after crimping?
It is a bare aluminum-bodied compression splice with no insulation on it, so the joint has to be insulated in the field with tape, heat shrink, or a cover after crimping.
3) Is the KL57-1 a crimp splice or a set-screw connector?
Crimp. It is a compression splice, so it needs a hydraulic or battery crimp tool with the correct die for the barrel, not a wrench. If you want a tool-free joint, look for a set-screw or mechanical service entrance connector instead.
4) Can I use the Blackburn KL57-1 to splice copper to aluminum?
The KL57-1 is an aluminum service entrance splice. Aluminum-bodied compression splices of this type are dual rated for aluminum and copper conductors only when the body is marked AL9CU; the KL57-1 is catalogued as an AL service entrance splice, so use it on aluminum service entrance conductors at 4/0 to 2/0. For a mixed copper-to-aluminum transition, specify a connector marked for both metals.
5) Does the KL57-1 meet the connector standard for service entrance work?
It passes the requirements of ANSI C119.4, the standard covering connectors for use between aluminum and aluminum or aluminum and copper bare overhead conductors. That is the reference most utility and service entrance specs call out for compression connectors.
6) How long is the KL57-1 splice barrel, and will it fit in my meter socket or weatherhead?
The splice is 3-1/2 inches overall, so budget at least that much straight length plus room for the crimp tool head in the enclosure or gutter. In a tight meter socket or pull section, measure the clear space before committing to a compression joint.
7) Is the Blackburn KL57-1 sold individually or in a bag?
Each. One splice per selling unit, so order one per conductor you are joining. A two-conductor reducing splice at each of two phases means two pieces.
8) What is the manufacturer part number for this Blackburn reducing splice?
Blackburn KL57-1. That is the number to give a distributor when matching the 4/0 to 2/0 aluminum service entrance reducing splice.
