Blackburn SC 400-HM – Frequently Asked Questions
1) What is the Blackburn SC 400-HM used for?
The SC 400-HM is a compression splice for joining two conductors in a straight run. It is a two-conductor barrel that you crimp with a compression tool, not a mechanical set-screw or bolted connector, so once it is compressed the joint is permanent.
2) Does the Blackburn SC 400-HM splice come insulated, or do I need to cover it after crimping?
It is a bare splice with no insulation on it. You have to insulate the finished joint yourself, with heat shrink, a cold shrink tube, or tape build-up rated for the circuit voltage. Plan that material into the job before you cut the cable.
3) Can I install a Blackburn compression splice with a set-screw or hand tool instead of a crimper?
No. This is a compression fitting, so it needs a hydraulic or battery compression tool with the correct die for the barrel. There is no set screw and no bolt. If you need a connection you can make with a wrench and take apart later for testing, use a bolted or mechanical set-screw splice instead.
4) Is the Blackburn SC 400-HM splice suitable for aluminum conductors as well as copper?
The barrel is tin-plated. Tin plating is what lets a connector be used on aluminum as well as copper without setting up a galvanic couple at the contact surface, and it also slows oxidation on copper in damp or below-grade pulls. Match the die and the conductor size to the barrel marking when you crimp.
5) How long is the Blackburn SC 400-HM splice barrel?
The stated product size is 2.562 inches. That length matters for two reasons on a job: you need that much straight, unsupported cable to seat both conductors, and your insulating sleeve has to cover the full barrel plus overlap onto the jacket at each end.
6) Is the Blackburn SC 400-HM sold individually or in a pack?
Sold each, one splice per unit, so order one per joint. A straight splice on a two-conductor run takes one per conductor, not one per cable.
7) Where is the Blackburn SC 400-HM splice made?
It is manufactured in the United States, which is the answer public agencies and institutional buyers need when a job carries domestic-sourcing language in the spec.
