Blackburn 4AAW – Frequently Asked Questions
1) Can I use the Blackburn 4AAW aluminum split bolt on copper wire?
The 4AAW body is aluminum with an electro tin-plated finish, which is the standard construction for connectors rated for aluminum and for aluminum-to-copper combinations. Tin plating is what keeps the aluminum body from reacting directly against copper. Match the connector marking on the part to the conductor combination you are actually splicing before you make the joint.
2) Does the Blackburn 4AAW split bolt come with a spacer?
Yes. The 4AAW is the version supplied with the spacer (the "W/SP" in the description). The spacer sits between the run and tap conductors inside the bolt so the two wires are separated and each seats squarely under pressure, which is what you want when you're combining dissimilar conductors.
3) Do split bolts like the Blackburn 4AAW need to be taped or insulated after installation?
Yes. A split bolt is a bare mechanical connector, not an insulated one, so the completed joint has to be re-insulated to the level of the conductor insulation, typically with rubber splicing tape followed by vinyl electrical tape, or a suitable insulating cover. Nothing about the 4AAW's aluminum, tin-plated body provides that insulation.
4) Is a split bolt the right choice, or should I use a compression or set-screw connector instead?
A split bolt like the 4AAW is the fast, tool-light option: it's a mechanical connector you tighten with a wrench, good for a tap or splice you may need to open later, and it needs no dies or crimper. A compression connector is the choice when you want a permanent, non-reopenable joint and have the crimp tool for it. Multi-tap set-screw blocks make more sense when you're landing three or more conductors in one place rather than a single run-and-tap.
5) What is the manufacturer part number and country of origin for the Blackburn aluminum split bolt with spacer for 2-8 solid?
Blackburn part number 4AAW, made in Mexico. If you're standardizing a stockroom or matching what's already in an existing splice, 4AAW is the number to specify: aluminum body, tin-plated, with spacer, 2-8 solid.
