Blackburn AC336 – Frequently Asked Questions
1) What conductor size does the Blackburn AC336 aluminum compression splice take?
The AC336 is sized for 336.4 kcmil aluminum conductor, which is the size stamped into the part and the reason it is designated AC336. It is a full tension splice, so it is built to carry the mechanical load of the run as well as the current, not just make an electrical joint.
2) Is the AC336 splice a compression fitting or a bolted mechanical connector?
Compression. The AC336 is crimped with a hydraulic compression tool and die, not bolted, so once it is pressed it is a permanent joint. Budget for the correct die set for a 336.4 aluminum sleeve before the crew goes up.
3) Does the AC336 splice meet the utility standard for connectors?
It is built to ANSI C119.4, the standard covering electric connectors for use between aluminum and copper conductors. That is the spec most utility and line-work drawings call out for a splice of this class.
4) Is the Blackburn AC336 insulated, or do I have to cover it after crimping?
Bare. There is no insulation on the AC336 sleeve, so on any application that is not an open overhead conductor you are responsible for the covering, whether that is a heat shrink or cold shrink sleeve, tape build-up, or a molded cover rated for the voltage of the circuit.
5) Can I use the AC336 to splice copper conductor to aluminum?
The AC336 is an aluminum-bodied splice made for 336.4 aluminum conductor on both ends. For a copper-to-aluminum transition, order a connector specifically identified as a bimetallic or AL/CU transition splice rated for the two sizes you are joining. Putting bare copper into an aluminum barrel invites galvanic corrosion at the joint.
6) How long is the Blackburn AC336 splice body?
10 inches overall. That length matters for two reasons: you need that much clear working space on the span or in the trench to make the crimp, and on a long barrel like this you normally run multiple crimps along the sleeve from the center outward rather than a single press.
7) How many conductors does one AC336 splice join?
Two. It is a straight inline splice, one conductor entering each end of the 10 inch barrel, joining two lengths of 336.4 aluminum into a continuous run. It is not a tap or a parallel connector, so if you are branching off a run rather than extending it, this is the wrong body.
8) Where is the Blackburn AC336 splice made?
Mexico. That is the stated country of origin, which is the line a government or utility procurement office typically needs for domestic-preference paperwork on a bid.
