Blackburn RCJ477 – Frequently Asked Questions
1) What conductor size does the Blackburn RCJ477 jumper sleeve fit?
The RCJ477 is sized for 477 ACSR conductor. It is a single-size compression sleeve, so it will not take a different code conductor size, and both ends are sized the same for that conductor.
2) Is the RCJ477 a full tension splice or a partial tension sleeve?
Partial tension. The RCJ477 meets ANSI C119.4 at the 40 percent partial tension requirement, so use it as a jumper sleeve where the conductor is not carrying line tension. For a line splice that has to hold full rated conductor strength, you need a full tension compression splice instead.
3) How long is the Blackburn RCJ477 sleeve?
8-3/4 inches overall. That length matters on a jumper loop or inside a cutout box, since you need enough straight conductor on each side of the sleeve for the full compression die sequence.
4) Is the Blackburn RCJ477 insulated?
No insulation on it. The RCJ477 is a bare compression sleeve, so any covering or re-insulation on an insulated jumper has to be added separately with tape or a cover.
5) How many conductors does the RCJ477 jumper sleeve join?
Two. It is a straight two-conductor splice, one 477 ACSR conductor entered in each end and compressed with the proper die.
6) Does the RCJ477 need a compression tool, or can it be bolted?
It is compression only. The RCJ477 has no bolts or set screws, so it has to be crimped with a hydraulic compression tool and the die matched to the sleeve. There is no mechanical alternative install for this part.
7) Is the Blackburn RCJ477 sold individually or in a box quantity?
Sold each, so you can order the exact count of sleeves a job needs rather than a carton.
8) Where is the Blackburn RCJ477 made?
Mexico. That is the stated country of origin, which utilities and municipal buyers often need on record for procurement documentation.
