Blackburn AC40 – Frequently Asked Questions
1) What conductor size does the Blackburn AC40 compression splice take?
The AC40 is sized for 4/0 aluminum conductor, splicing two conductor ends end to end. It is a full tension aluminum splice, so it is meant for the 4/0 size called out in its description and not as a reducing or dual-size connector.
2) Is the Blackburn AC40 a full tension splice or just an electrical joint?
It is a full tension compression splice, meaning the joint is rated to carry mechanical load on the conductor as well as current. That is what makes it suitable for overhead aluminum runs where the splice has to hold line tension, rather than a slack service loop only.
3) Can I splice a copper conductor to aluminum with the Blackburn AC40?
The AC40 is an aluminum bodied splice sized for 4/0 aluminum on both ends, so treat it as an aluminum to aluminum joint. For a copper to aluminum transition you want a connector specifically marked for dual metal service; mixing metals in a splice not marked for it risks galvanic corrosion at the joint.
4) Does the AC40 splice come insulated or do I need to cover it?
No insulation is supplied on the AC40; it is a bare aluminum barrel. You cover the finished joint yourself with the tape, tubing, or cover your spec calls for, or leave it bare on overhead work where that is accepted practice.
5) What standard does the Blackburn AC40 aluminum splice meet?
It is built to ANSI C119.4, the standard covering connectors for use between aluminum and aluminum or aluminum and copper conductors. Utility and institutional specs that call out C119.4 class connectors for aluminum splicing are satisfied by that designation.
6) Do I need a hydraulic crimper for the Blackburn AC40, or can I use a mechanical bolted splice instead?
The AC40 is a compression fitting, so it requires a die set crimper, and on a 9-1/2 inch 4/0 aluminum barrel that means a hydraulic or battery hydraulic tool with multiple crimps along the length. If you do not have compression tooling on the truck, a bolted or mechanical splice connector is the alternative, though it will not give you the full tension performance a compression splice does.
7) Is the AC40 sold in packs or individually?
Sold each. Order one per splice point, so a two conductor repair on a run needs two pieces. Country of manufacture is Mexico.
8) What is the exact part number to order for a Blackburn 4/0 aluminum tension splice?
Blackburn AC40 is the manufacturer part number, a single catalog item with no finish or size options to choose.
