Blackburn RS4040 – Frequently Asked Questions
1) What conductor size does the Blackburn RS4040 service entrance splice take?
The RS4040 is a service entrance compression splice sized for 400 kcmil to 336 kcmil aluminum conductor, which is where the 400-336 in the part name comes from. It is a splice body, not a range-taking mechanical connector, so the conductor has to fall in that size range and be crimped with the matching die.
2) Is the Blackburn RS4040 splice insulated, or do I have to tape or sleeve it?
It comes bare, with no insulation on the body. Any covering the job requires, tape or heat shrink, is a separate item you add after crimping.
3) Does the RS4040 need a hydraulic crimper, or can I torque it down like a split bolt?
This is a compression splice, so it is installed with a crimp tool and the correct die, not with a set screw or bolted pressure. If you want a wrench-tightened joint instead, you need a mechanical or set-screw type connector rather than this one.
4) Can I use the Blackburn RS4040 on copper conductor, or is it aluminum only?
The RS4040 is an aluminum service entrance splice. It is built to ANSI C119.4, the standard covering connectors for aluminum and copper conductors, so check the conductor marking on the body against what you are splicing before you crimp.
5) How much room do I need in the pull box or trough for this splice?
The barrel measures 7-1/2 inches long, so allow for that plus bending room on each conductor end when you lay out a handhole, trough, or meter can splice.
6) What standard does the Blackburn RS4040 splice meet for a utility or inspector sign-off?
It is built to ANSI C119.4, the standard for connectors used with aluminum and copper conductors. The manufacturer part number is RS4040 and it is made in Mexico if country of origin matters for your procurement paperwork.
7) Is the Blackburn RS4040 sold individually or in a bag?
Sold each, one splice per unit, so order one per conductor you are splicing. A three-phase service with a neutral means four.
