Blackburn KL67-1 – Frequently Asked Questions
1) What conductor sizes does the Blackburn KL67-1 service entrance splice take?
The KL67-1 is a two-conductor service entrance splice sized for a 4/0 run on the A side and 2/0 on the B side, which is how the part is designated (A:4/0 B:2/0). It joins one conductor to the other, so you need one splice per phase or per conductor pair, and it is sold each.
2) Is the KL67-1 a compression splice or a mechanical set-screw connector?
Compression. The KL67-1 is crimped with a hydraulic or battery compression tool and the correct die, not tightened with set screws. If you want a connector you can install with a wrench and re-open later, you need a mechanical service entrance connector instead, not this one.
3) Does the Blackburn KL67-1 splice come insulated, or do I have to cover it?
It ships bare. The KL67-1 has no insulation on it, so after crimping you insulate the joint yourself with heat shrink, tape, or a cover rated for the application and voltage. Plan that material into the job.
4) Can I use the KL67-1 to splice aluminum service entrance conductors to copper?
The KL67-1 is an aluminum service entrance splice, designated AL in the part description. Use it on aluminum conductors of the stated 4/0 and 2/0 sizes. For an aluminum-to-copper transition, specify a connector listed for that combination rather than this one.
5) How long is the KL67-1 splice body, and will it fit in my meter socket or pedestal?
The barrel measures 3-1/2 inches, so allow at least that much straight length plus room for the crimp tool head and your insulation build-up. In tight meter sockets or enclosures, dry-fit the tool before you cut the conductors to length.
6) Does the Blackburn KL67-1 meet ANSI C119.4 for underground and service connectors?
Yes, it passes the requirements of ANSI C119.4, the standard covering connectors for use between aluminum and copper conductors. That is the reference most utility and inspection specs call out for service entrance splices.
7) How many KL67-1 splices do I need for a three-phase service reduction?
One per conductor. The KL67-1 handles a single pair, one 4/0 to one 2/0, so a three-phase plus neutral job takes four, and a single-phase service with a neutral takes three. They are sold individually, so order by conductor count and add a spare for a bad crimp.
8) What part number do I order for the Blackburn 4/0 to 2/0 service entrance splice?
Order Blackburn KL67-1. That is the manufacturer part number for the aluminum compression service entrance splice with the 4/0 A barrel and 2/0 B barrel, made in Mexico, and it is sold as a single piece.
