Blackburn KL58-1 – Frequently Asked Questions
1) What conductor sizes does the Blackburn KL58-1 service entrance splice accept?
The KL58-1 is a two-conductor reducing splice: one barrel takes 4/0 and the other takes 3/0, per the A:4/0 B:3/0 callout on the part. That makes it the one to reach for when you are splicing a 4/0 run to a 3/0 run rather than like-to-like.
2) Do I need a crimping tool for the Blackburn KL58-1, or can it be tightened with a wrench?
It is a compression splice, so it has to be crimped with a hydraulic or battery compression tool and the correct die. There are no setscrews and no wrench option. If you want a wrench-tightened connection, you need a mechanical set screw splice instead.
3) Is the Blackburn KL58-1 splice insulated, or do I have to tape or sleeve it?
Bare, no insulation on the splice body. You finish it yourself, typically with heat shrink tubing or an insulating tape build-up, once the crimp is made. Budget for that material on the job.
4) Can I use the KL58-1 splice on copper conductors, or only aluminum?
It is an aluminum-bodied service entrance splice (the AL in the part description). Aluminum bodies of this type are commonly dual-rated AL9CU, but confirm the rating stamped on the barrel before putting copper in it. For a straight aluminum-to-aluminum or aluminum-to-copper service entrance splice at 4/0 to 3/0, this is the intended application.
5) Does the Blackburn KL58-1 meet utility connector test standards?
Yes. It passes the requirements of ANSI C119.4, the standard covering electric connectors for use between aluminum and aluminum or aluminum and copper conductors. That is the test most utilities and inspectors look for on a service entrance splice.
6) How long is the KL58-1 splice body, and will it fit inside my meter socket or pedestal?
The splice measures 3-1/2 inches, so plan on at least that much straight run plus room for the crimp tool head and your insulation build-up. In tight meter sockets or pull boxes, check that clearance before you strip conductors.
7) Is the Blackburn KL58-1 sold individually or in a bag?
Sold each. One splice per unit, so order one per connection point you are making. Model number to specify is KL58-1.
8) Where is the Blackburn KL58-1 splice made?
Manufactured in Mexico. Useful if your project carries country-of-origin documentation requirements on submittals.
