Blackburn RC4BB – Frequently Asked Questions
1) Is the Blackburn RC4BB a full-tension splice or just a distribution connector?
The RC4BB is an aluminum full-tension distribution compression splice, built to ANSI C119.4 for connectors used on distribution conductors. It joins two conductor ends (2 conductors) in a single compressed sleeve, so the splice carries mechanical load as well as current rather than acting only as an electrical tap.
2) Does the Blackburn RC4BB splice come insulated, or do I have to cover it myself?
No insulation on it. The RC4BB is a bare compression sleeve with no insulating jacket, so on any installation that needs covering you supply the cover or tape separately. That is normal for overhead distribution work, where the splice is left bare in air.
3) What tools do I need to install a Blackburn RC4BB splice?
It's a compression connection, so it takes a hydraulic or battery compression tool with the correct die, not a wrench or set screws. Compress it per the die/number of crimps marked on the sleeve, working from the center out. No bolts are involved.
4) How long is the Blackburn RC4BB sleeve, and how much conductor do I need to strip?
The sleeve is 12 inches overall, which means each conductor end seats roughly half that depth. Plan your cut and clean-up length accordingly and leave enough slack in the span to pull both ends fully into the barrel before crimping.
5) Does the Blackburn RC4BB meet utility connector standards for a spec submittal?
It's built to ANSI C119.4, the standard covering electric connectors for use between aluminum and copper bare overhead conductors, which is the reference most utility and distribution specs cite for compression splices. Country of origin is Mexico if your submittal package requires it.
6) Is the Blackburn RC4BB sold in a pack or individually?
Individually. The selling unit is each, model RC4BB, so a two-conductor splice job takes one unit per splice point. Order by the count of splices on the print, not by pairs.
