Blackburn RC477 – Frequently Asked Questions
1) What conductor does the Blackburn RC477 compression splice fit?
The RC477 is an aluminum tension distribution compression splice sized for 477 ASCR conductor. It joins two conductor ends, so one splice completes one run, and it is a compression fitting, not a bolted or mechanical connector.
2) Is the RC477 splice rated as a full tension splice?
It is a tension splice for distribution conductor, meaning it is built to carry mechanical load across the joint rather than just make an electrical connection. It is manufactured to ANSI C119.4, the standard for connectors used on aluminum and copper distribution conductors.
3) Can I use the RC477 on copper conductor?
No. The RC477 is an aluminum splice made for 477 ASCR aluminum conductor. Splicing copper calls for a copper or a bimetallic connector rated for that combination.
4) How long is the Blackburn RC477 splice body?
Product size is listed at 24 inches, which is typical of a full tension compression sleeve: the length gives the crimp area needed to hold conductor tension on both sides of the joint. Allow for that length plus your press jaw travel when planning the span work.
5) Do I need a hydraulic compression tool to install the RC477?
Yes. This is a compression connector, not a mechanical or set-screw type, so it requires a hydraulic press and the correct die set for the sleeve. No tooling or dies ship with the splice, and it is sold as a single piece.
6) Is the RC477 splice insulated, and can it be direct buried?
It is a bare, uninsulated aluminum sleeve with no insulation material. For overhead distribution that is normal. If your application needs a covered or insulated joint, you will need separate covering or a different connector style.
7) How is the Blackburn RC477 sold, and what is the part number I should order?
Order by manufacturer part number RC477, sold each. Country of origin is Mexico.
