Blackburn ASC 300 – Frequently Asked Questions
1) What conductor sizes does the Blackburn ASC 300 splice take?
The ASC 300 is sized for aluminum conductors from 266.8 through 300 kcmil, concentric stranded. It is a straight (inline) splice joining two conductor ends, so both sides need to fall in that range. Outside 266.8 to 300 kcmil you need a different ASC catalog number.
2) Is the Blackburn ASC 300 a compression splice or a mechanical set-screw connector?
Compression. The ASC 300 is installed with a hydraulic or battery crimp tool and the matching die, not tightened with a set screw. If you want a connector you can install with a wrench and re-enter later, a mechanical splice is the other route; compression gives a permanent, sealed-metal joint instead.
3) Does the Blackburn ASC 300 come insulated, or do I need to cover the splice?
It ships bare, with no insulation on the barrel and a bare (unplated) surface finish. Any underground, wet-location or energized run will need the joint insulated after crimping, typically with heat shrink or a tape/mastic build, per the installation spec on the job.
4) Can the ASC 300 splice be used on copper conductor?
The ASC 300 is an aluminum-body splice made for aluminum conductor. For a copper-to-copper inline splice, or a copper-to-aluminum transition, use a connector specifically listed for that combination rather than this one.
5) Will the ASC 300 work on compact or compressed stranded aluminum, or only concentric?
It is a concentric-stranded splice, sized to the barrel diameter of concentric 266.8 to 300 kcmil aluminum. Compact and compressed conductors of the same kcmil have a smaller outside diameter, so a splice built for that stranding class is the correct part instead.
6) How is the Blackburn ASC 300 sold, one splice or a box?
Sold each, so one splice per unit. Order the count you need for the job plus spares, since a mis-crimp on a compression barrel cannot be reworked, the barrel has to be cut out.
7) What is the exact part number and origin of the Blackburn 266.8-300 aluminum splice?
Blackburn catalog number ASC 300, made in the United States. That is the number to quote on a submittal or a repeat order for the same aluminum inline splice.
