Blackburn U 1 B 81 – Frequently Asked Questions
1) What wire size does the Blackburn U 1 B 81 compression splice take?
The U 1 B 81 is the 8 to 10 AWG size in Blackburn's aluminum service entrance compression splice line, and it carries the green color code that identifies that range on the die chart. Green tells the installer at a glance which die groove to crimp it with, so verify your conductor gauge falls in 8 through 10 before you crimp, because a compression splice cannot be backed out once it is formed.
2) Is this splice for aluminum conductor, copper, or both?
It is an aluminum-body service entrance splice. The barrel is aluminum, which is what makes it suitable for aluminum service entrance conductor. If you are splicing copper to aluminum you need a connector specifically rated AL9CU dual rated, not an aluminum-only body.
3) Does the U 1 B 81 come insulated, or do I have to tape or heat shrink it?
No insulation on this one. The catalog lists insulation material as none, so the barrel is bare aluminum and you supply the covering yourself, typically heat shrink or a rubber and vinyl tape build-up rated for the circuit voltage. Plan that material into the job before you head out.
4) Will this compression splice satisfy an inspector on a service entrance repair?
The U 1 B 81 is built to ANSI C119.4, the standard for connectors used on electrical conductors, which is the reference an inspector or a utility spec typically calls out for compression connectors. It is also made in the United States, which matters on public and federally funded work with domestic content requirements.
5) How many conductors does this Blackburn splice join?
Two. It is a straight two-conductor butt splice, one conductor in each end of a 2 inch long barrel. For tapping a third conductor or making a multi-way connection you want a tap connector or a multi-port lug, not this splice.
6) Can I crimp this with pliers or a bolt-type tool, or do I need a compression tool?
Compression only. The connection type is compression, meaning the barrel is deformed onto the conductor with a hydraulic or battery crimper and the matching die, and the green color code identifies which die to use. There are no set screws or bolts, so there is nothing to tighten by hand and nothing to retorque later.
7) Is the U 1 B 81 sold each or in a bag of connectors?
Sold as each, so one splice per unit ordered. If you are stocking a service truck or splicing a three-wire drop, order the count you need up front rather than assuming a multi-pack.
8) How do I confirm I grabbed the right size out of the bin on the job?
Check the color first. This splice is marked green and brown, and green is the identifier for the 8 to 10 AWG size in the line, so a green marked 2 inch aluminum barrel is the U 1 B 81. Matching the color to the die groove on your crimper is the quickest field check before you pull the trigger.
