Blackburn U 1 N 108 – Frequently Asked Questions
1) Is the Blackburn U 1 N 108 splice a crimp connector or a set-screw type?
It's a compression splice. You crimp it with a die-type compression tool, not a screwdriver, so there are no set screws to torque or re-torque later. The body is pre-insulated and 3-1/4 inches long, sized for a two-conductor butt splice.
2) How many conductors does the Blackburn U 1 N 108 splice join?
Two. It is a straight butt splice with one conductor entering each end, not a tap or a multi-port connector. If you need to tie in a third conductor you need a different connector body.
3) Does the Blackburn U 1 N 108 meet ANSI C119.4 for compression connectors?
Yes, it is built to ANSI C119.4, the standard covering connectors for underground and above-ground distribution conductors. That is the reference an inspector or a utility spec will ask for on a compression splice.
4) Can this insulated aluminum splice be used on both aluminum and copper service entrance conductors?
The U 1 N 108 is an insulated aluminum-bodied compression splice built for service entrance work. ZenSupply's record covers it as an aluminum splice for service entrance cable; for a copper-to-aluminum transition confirm the conductor materials marked on the connector body before crimping, since dual-rated bodies are marked AL9CU.
5) Do I need to tape or heat-shrink over this splice after crimping?
No separate tape or sleeve is required for the connector itself. The U 1 N 108 ships pre-insulated over the crimp barrel, so the insulation is part of the connector. Any additional protection is a matter of your local practice or wet-location requirement, not a gap in the product.
6) What does the yellow and green color on Blackburn compression splices mean?
The U 1 N 108 is yellow/green. On Blackburn compression connectors the color is a die and conductor-size index: you match the color to the corresponding die in your crimp tool so you get the right compression on the barrel. Use the color code on the body to pick the die, not a generic setting.
7) What is the correct manufacturer part number to order this Blackburn insulated aluminum splice?
Order it as Blackburn U 1 N 108. That is the manufacturer part number for the insulated aluminum service entrance compression splice, and it is the number to quote to avoid picking up a similar uninsulated body.
8) Will a 3-1/4 inch splice fit inside my meter socket or service entrance enclosure?
The connector body is 3-1/4 inches long, and you need that length plus bending room for the conductors on each side. In a tight meter socket or a shallow trough, measure the clear space before you commit, because a compression splice cannot be shortened the way a set-screw body sometimes can be repositioned.
9) How is the U 1 N 108 splice sold, individually or in a bag?
Each. One splice per selling unit, so order the exact count of joints you're making rather than a multi-pack.
10) Is the Blackburn U 1 N 108 made in the USA?
Yes, country of origin is the United States. That matters on public work with domestic-content requirements, and it is worth capturing on the submittal.
