Blackburn RCJ40-BB – Frequently Asked Questions
1) Is the Blackburn RCJ40-BB a full tension splice or a partial tension splice?
Partial tension. The RCJ40-BB meets ANSI C119.4 at the 40 percent partial tension level, so it is intended for distribution work where the conductor is not carrying full rated mechanical tension. If your application needs a full tension splice for a transmission span, this is not the right part.
2) Do I need a hydraulic crimper for the Blackburn RCJ40-BB splice, or can it be bolted?
It is a compression splice, so it is installed by crimping with a compression tool and the correct die, not by bolting or set screws. Plan on a hydraulic or battery compression tool on site.
3) Is the Blackburn RCJ40-BB an aluminum splice, and how many conductors does it join?
It is an aluminum-bodied distribution compression splice that joins two conductors, one entering each end. It is not a tap or a multi-port connector, so for more than two runs you need a separate connector.
4) Does the RCJ40-BB splice come insulated, or do I have to tape or sleeve it?
Bare metal, no insulation on the body. If the splice needs to be insulated for the installation, you cover it yourself with tape, a cold shrink or heat shrink sleeve, or a splice cover.
5) How long is the Blackburn RCJ40-BB splice body, and will it clear my span or duct?
The splice measures 6-3/4 inches, so allow at least that much straight, accessible conductor plus room for the crimp tool head on each side. Tight pull boxes and short slack loops are the usual place this length becomes a problem.
6) Is the Blackburn RCJ40-BB sold individually or in a box?
Sold each, so order one per splice point. Make sure your count covers both conductors of a run if you are splicing more than one phase.
7) Where is the Blackburn RCJ40-BB compression splice made?
Manufactured in Mexico. That country of origin is what a public agency or institutional buyer needs for domestic-content review on a bid package.
