Blackburn ASC 400 TN – Frequently Asked Questions
1) Is the Blackburn ASC 400 TN splice rated for aluminum conductors or copper only?
The ASC 400 TN is an aluminum compression splice with a tin-plated surface. The tin plating is what lets it be used on aluminum conductors as well as copper, since it keeps the aluminum barrel from making direct bare contact with copper strands. It is built for 400 kcmil conductors.
2) How many conductors does the ASC 400 TN compression splice take?
Two. It is a straight two-conductor splice, so you get one cable in each end and crimp, joining a single run. If you need to tap a branch off a main or bring three conductors together, this is not the fitting for it.
3) Does the ASC 400 TN come insulated, or do I have to tape or shrink over it?
It ships bare, with no insulation on the barrel. Once the crimp is made you have to re-insulate the joint yourself, with heat shrink, a cold-shrink sleeve, or tape built back to the cable insulation level. Plan that material into the job.
4) Can I install the ASC 400 TN with a mechanical wrench, or does it need a crimp tool?
Compression only. It is a crimp-type connector, not a set-screw or bolted mechanical splice, so it needs a hydraulic or battery compression tool with the correct die for a 400 kcmil aluminum barrel. If you do not have a compression tool on the truck, you want a mechanical set-screw splice instead.
5) What standard does the Blackburn ASC 400 TN meet for submittals?
ANSI C119.4, the standard covering connectors for use between aluminum and copper conductors. That is the reference to cite on an electrical submittal or spec sheet for this splice.
6) How long is the ASC 400 TN splice barrel? I need to know if it fits in my pull box.
The splice measures 3-3/4 inches. Allow for that length plus your re-insulation buildup and the cable bending radius on each side when you are checking clearance in a pull box, gutter, or handhole.
7) Is the Blackburn ASC 400 TN made in the USA for a Buy American job?
Country of origin is the United States, which is the line procurement officers on federally funded and Buy American Act work usually need documented.
8) Is the ASC 400 TN sold individually or in a bag of ten?
Each. Pricing and packaging are per single splice, so order one per joint. Remember a three-phase run with a neutral needs four of them.
