Blackburn AC 250 TN – Frequently Asked Questions
1) What conductor size does the Blackburn AC 250 TN compression splice take?
The AC 250 TN is sized for 250 kcmil aluminum conductor, joining two cable ends in one barrel. It is a two-conductor splice, so it is a straight end-to-end butt connection, not a tap or a multi-port device.
2) Can I use this aluminum splice on copper conductors, or in an aluminum-to-copper run?
The barrel is aluminum with a tin plating, which is the standard construction for splicing aluminum conductor and for dual-rated AL/CU service. The tin plate is what keeps the aluminum body from reacting directly against copper strands. It meets ANSI C119.4, the standard that covers connectors for aluminum and copper conductors in underground and general power applications. If your job spec calls for a specific AL9CU or AL/CU marking, match that marking on the connector before you crimp.
3) Does this splice come insulated, or do I have to tape or heat-shrink it?
Bare metal, no insulation on the connector itself. Anywhere the splice is not in a sealed enclosure you will need to re-insulate it yourself, typically with heat shrink tubing, a cold-shrink sleeve, or a taped buildup back to the cable jacket rating.
4) How long is the AC 250 TN splice barrel, and will it fit inside a standard splice box?
Overall length is 5-1/4 inches. That is the number to check against the working space in your handhole, pull box, or gutter, and it sets how much straight cable you need on each side to land both crimps without bending against the die.
5) Is the Blackburn AC 250 TN a crimp connector or a set-screw connector?
Compression only. It is installed with a hydraulic or battery crimp tool and the correct die for the barrel, not tightened with a hex key. If you need a connector you can install with hand tools or re-open later, a set-screw or mechanical splice is the type to look for instead.
6) Is this splice made in the USA for a Buy American job?
Country of origin on the Blackburn AC 250 TN is the United States, which is the line item most public and institutional procurement packages ask for on electrical connectors.
7) Is the AC 250 TN sold individually or only in the 50-piece box?
The selling unit is each, so you can order the exact count the job needs even though the manufacturer packs it in 50-piece quantities. Useful if you are stocking a service truck rather than a feeder pull.
