Blackburn APS41 – Frequently Asked Questions

1) What wire sizes does the Blackburn APS41 split-bolt connector take?
The Blackburn APS41 is rated for 4/0 through 2 AWG stranded conductors. That range covers typical service entrance and feeder work, and both conductors in the connection need to fall inside it. If your run is smaller than 2 AWG or larger than 4/0, this is the wrong body size.
2) Can I use an aluminum split-bolt like the APS41 on copper conductors?
The APS41 body is aluminum with an electro tin-plated finish. Tin plating over aluminum is what allows this style of connector to be used on either metal and in mixed copper-to-aluminum splices, because the plating keeps dissimilar metals from contacting directly. Check the marking on the connector for the AL/CU dual rating before making a mixed connection, and use an oxide inhibitor on the aluminum conductor as your installation practice requires.
3) What does the dual split-bolt design on the APS41 do differently from a standard single split bolt?
A dual split-bolt has two bolts instead of one, so clamping pressure is spread over a longer contact length on the conductors. On heavy stranded cable in the 4/0 to 2 AWG range that means more bearing surface on the strands and less tendency for the joint to loosen as the cable settles. Installation is the same idea: seat both conductors in the slot, tighten both bolts, then tape or boot the splice for insulation.
4) Does the APS41 split-bolt come insulated, or do I have to cover it?
It ships as a bare mechanical connector. A split-bolt splice is not insulated by itself, so you finish the joint with rubber and vinyl tape or a snap-on insulating cover sized for the connector. Budget for that cover material on every splice when you order.
5) Can I use the APS41 split-bolt for a grounding electrode or bonding connection?
Grounding system connections are among the listed applications for this connector, and the UL E9809 mechanical connector listing is what makes that acceptable. Match the conductor size to the 4/0 to 2 AWG stranded range, and confirm your local requirement on whether a direct-burial or concrete-encased connection needs a connector specifically marked for that use.
6) Will a tin-plated aluminum split-bolt hold up in a damp or outdoor pull box?
The electro tin-plated surface on the APS41 is there for corrosion resistance, which is why this style gets used in service entrance and utility distribution work. It is still a bare mechanical connector, so the splice itself has to be insulated and the enclosure has to suit the location; the plating protects the connector body, not the joint.
7) Is the Blackburn APS41 sold individually or in a box quantity?
The APS41 is sold each, so an order quantity of 10 gets you 10 connectors. Remember to count both ends of a splice job and add insulating tape or covers separately.
