Blackburn AC 2-HM – Frequently Asked Questions
1) What is the Blackburn AC 2-HM splice actually used for?
The AC 2-HM is an aluminum straight reducing compression splice, used to join two conductors of different sizes end to end in a straight run. It takes two conductors and is crimped with a compression tool rather than bolted or set-screwed, so the joint is permanent once made.
2) Does the AC 2-HM come insulated, or do I have to tape or sleeve the joint myself?
It ships bare, with no insulation on the barrel. Any covering the installation calls for, tape, heat shrink, or a cold shrink sleeve, gets added in the field after the crimp.
3) Does this Blackburn splice meet ANSI C119.4 for electrical connectors?
Yes. The AC 2-HM is built to ANSI C119.4, the standard covering connectors for underground and building wire applications, which is what most utility and institutional specs reference for a compression splice.
4) Can I use this on copper conductors?
The AC 2-HM body is aluminum. Aluminum compression barrels are made for aluminum conductor, and a copper-to-aluminum transition needs a bimetallic connector instead, not a straight aluminum reducing splice. If you are joining copper to aluminum, ask for a dedicated bimetal or AL9CU-rated splice.
5) How much room do I need in the box or enclosure for this splice?
The barrel is 3-15/32 inches long, so plan on that much straight length plus the crimp tool's die clearance at each end. In a tight pull box or handhole, measure before committing, a reducing compression barrel cannot be shortened.
6) Is this a set-screw splice I can install with a wrench?
No. It is a compression fitting, so it needs the matching hydraulic or battery crimp tool and die, not a hex key or wrench. If you want a tool-free mechanical joint, you need a set-screw or bolted splice instead.
7) Is this splice made in the USA for a Buy American job?
Country of origin on the AC 2-HM is the United States, which is what a government, school, or transit spec with domestic-content language will ask you to document.
8) What exact part number should I order for this Blackburn reducing splice?
Order Blackburn AC 2-HM. That is the manufacturer part number for the aluminum straight reducing compression splice, and there is only one configuration, so no finish or size suffix to add.
9) Is the Blackburn AC 2-HM sold individually or in a bag?
Sold each, one splice per unit, so quantities on a purchase order match the number of joints you are making.
