Blackburn 4CA – Frequently Asked Questions
1) What wire sizes does the Blackburn 4CA split bolt connector take?
The Blackburn 4CA is built for 2 through 4 solid conductor, as its description (2-4SLD) states. It is a split bolt with a spacer, so it is intended for tapping or splicing within that solid-wire range. Conductors outside 2 AWG to 4 AWG solid need a different size split bolt in the range.
2) Is the Blackburn 4CA aluminum connector rated for use on copper wire as well?
The 4CA body is aluminum, and aluminum-bodied split bolts in this family are the type used for aluminum-to-aluminum and aluminum-to-copper work rather than the copper-only bronze bodies. If your job is copper to copper only, a bronze or copper-alloy split bolt is the usual choice. Confirm the conductor combination against the marking on the connector before you make the tap.
3) What is the spacer on the Blackburn 4CA split bolt for?
The 4CA ships with a spacer (the W/SP in the part description). The spacer separates the run and tap conductors inside the bolt so each is held against the bolt body rather than crushing against each other, which is how the connector maintains even pressure on both wires. It is part of the assembly, not an add-on you order separately.
4) Does the 4CA need a torque wrench, or is it a compression connector?
It is a mechanical connector, not a compression fitting, so it installs with a wrench and needs no crimping tool or die set. That is the practical reason contractors and MRO crews keep split bolts on the truck: no press, no dies, and the joint can be taken apart later.
5) Do split bolts like the Blackburn 4CA need to be taped or insulated after installation?
Yes. The 4CA is a bare metal mechanical connector with no insulation of its own, so the completed splice has to be insulated in the field, typically with rubber splicing tape built up over the bolt and then covered with vinyl electrical tape, or with an insulating cover sized for the connector. Budget that material into the job.
6) How is the Blackburn 4CA sold, individually or in a box?
It is sold each, so quantity ordered equals the number of connectors you receive. Count one per splice or tap, plus spares, when you are pulling material for a job.
7) What is the exact part number and country of origin for the Blackburn 4CA?
Manufacturer part number 4CA from Blackburn, made in Mexico. Distributors cross-referencing catalogs should note the CA suffix marks it as the aluminum-bodied version with spacer for 2 to 4 solid conductor.
