Blackburn X 1 U 404 – Frequently Asked Questions
1) Is the Blackburn X 1 U 404 splice insulated, or do I have to tape or sleeve it after crimping?
There is no insulation on the X 1 U 404. The barrel is bare metal, so the joint has to be insulated in the field after crimping, typically with tape or heat shrink sized for the finished barrel.
2) What wire size does the Blackburn X 1 U 404 service entrance splice take?
It is a 4/0 splice, per the product name, and it joins two conductors end to end. Both ends take the same 4/0 size, so it is a straight splice rather than a reducer.
3) Is this a compression splice or a set screw connector?
Compression. The X 1 U 404 has to be crimped with a die tool, not tightened with an Allen key, so you need the matching compression tool and die for a 4/0 service entrance splice. If you want a tool-free joint, look for a mechanical set screw splice instead.
4) Does the Blackburn X 1 U 404 meet ANSI C119.4 for underground and service entrance connectors?
Yes, it is built to ANSI C119.4, the standard for connectors used with copper and aluminum conductors. That is the reference most utility and service entrance specs call out for a compression splice of this kind.
5) What does the orange color on this Blackburn splice mean?
The pink/orange marking is the color code that identifies the die and conductor size for the crimp, so an inspector can confirm the right die was used. Match the color and die index stamped on the barrel to your tool die.
6) How long is the barrel, and will it fit inside a meter socket or pull box?
The splice is 4 inches long overall, so allow at least that much straight run plus bending room for 4/0 conductors inside the enclosure. In a tight meter socket or CT cabinet, measure the clear space before committing to a compression splice of this length.
7) Is the Blackburn X 1 U 404 sold individually or in a bag of ten?
Sold each. Order one per splice point, and remember a three-wire service with a neutral needs one connector per conductor being joined.
8) Is this splice made in the USA for a Buy American job?
Country of origin on the X 1 U 404 is the United States, which is what a government or institutional buyer working to a domestic-content clause needs on the submittal.
