Blackburn AC266 – Frequently Asked Questions
1) What conductor size does the Blackburn AC266 compression splice take?
The AC266 is sized for 266.8 kcmil aluminum conductor, which is what the "266.8" in the name refers to. It is a full tension compression splice, so both ends take the same 266.8 kcmil aluminum cable. If your run is a different kcmil size, you need the matching splice for that size, not this one.
2) Can I use an aluminum compression splice like the AC266 on copper conductor?
No. The AC266 is an aluminum-bodied splice made for aluminum conductor. For copper, or for a copper-to-aluminum transition, you need a copper splice or a listed bimetallic (AL/CU) connector rated for that combination.
3) Is this splice rated to carry the full mechanical load of an overhead aluminum conductor?
Yes, it is a full tension splice, meaning it is built to take the conductor's tension as well as the current, which is what an overhead span between poles requires. A non-tension or bolted splice is only suitable where the conductor is supported and the joint carries no pull.
4) Does the Blackburn AC266 meet a recognized connector standard for utility work?
The AC266 is built to ANSI C119.4, the standard covering electric connectors for use between aluminum and aluminum or aluminum and copper conductors. That is the reference most utility and line specs call out for splices of this type.
5) How long is the AC266 splice barrel?
Overall size is 8-5/8 inches. That length matters for two reasons: it tells you how much straight, clean conductor you need on each side of the joint, and whether the finished splice will clear hardware, insulators, or a sleeve in the span.
6) Does this splice come insulated or do I need to cover it?
It is a bare splice with no insulation on the body. Any insulating or covering required by the application, tape, a cover, or a shrink sleeve, has to be added separately.
7) What tooling does an AC266 aluminum splice need to install?
This is a compression connector, so it is crimped with a hydraulic or battery compression tool using the die matched to the connector, not tightened with a wrench. There are no set screws or bolts. Plan on the compression tool, correct dies, and a wire brush and inhibitor practice appropriate to aluminum conductor.
8) How many conductors does the AC266 splice join, and is it sold individually?
It joins two conductors, one in each end of the barrel, for a straight inline splice. It is sold each, so order one per joint plus spares for the crew.
9) What is the exact part number and origin for this Blackburn splice?
Order it as Blackburn AC266. It is manufactured in Mexico, which is the detail a government or federally funded job may need for country-of-origin documentation.
