Blackburn RC40 – Frequently Asked Questions
1) What conductor size does the Blackburn RC40 compression splice take?
The RC40 is an aluminum full-tension distribution splice sized for 4/0 ACSR conductor. It joins two conductor ends, so it is a straight inline splice rather than a tap or a multi-port connector. If your line is a different ACSR size, you need the matching splice size, not this one.
2) Does the Blackburn RC40 splice meet ANSI C119.4?
Yes, the RC40 is built to ANSI C119.4, the standard covering connectors for use between aluminum and aluminum or aluminum and copper bare overhead conductors. That is the spec most utility and distribution drawings call out for a full-tension splice.
3) Will the RC40 hold the full rated strength of the conductor, or is it only for slack spans?
It is a full-tension distribution splice, meaning it is intended to carry the mechanical load of the 4/0 ACSR line itself rather than just make an electrical connection in a jumper or slack loop. For a non-tension jumper connection you would use a lighter-duty connector.
4) Is the Blackburn RC40 a bolted or compression connector?
Compression. The RC40 is installed with a hydraulic compression tool and the correct die set, crimped over both conductor ends. There is no bolt or set screw to torque, and once it is crimped it is not reusable.
5) How long is the Blackburn RC40 splice body?
18-1/2 inches. That length matters for clearance at the splice location and for planning your compression sequence, since a full-tension ACSR splice of this size takes multiple crimps along the barrel.
6) Is the Blackburn RC40 insulated, and can it be direct buried or used in a pedestal?
It is a bare connector with no insulation, intended for overhead bare distribution conductor. For an insulated or submersible application you want an insulated or submersible-rated connector instead, not this one plus tape.
7) What is the manufacturer part number and country of origin for this Blackburn splice?
The part number is RC40 from Blackburn, manufactured in Mexico. That is the number to reference on a submittal or when matching what is already installed on the line.
