Blackburn 10CA – Frequently Asked Questions
1) What wire size range does the Blackburn 10CA split bolt connector cover?
The 10CA handles conductors from 2/0 stranded down to 2 solid, so it covers the main and tap on most feeder splices in that band. If either conductor falls outside 2/0 stranded to 2 solid, you need a different split bolt size rather than forcing this one.
2) Is the Blackburn 10CA split bolt aluminum or copper bodied, and can I use it on aluminum conductors?
The body is aluminum, which is the construction used for aluminum and aluminum-to-copper mechanical splices. Copper-bodied split bolts are the ones restricted to copper only, so if your run is aluminum feeder, the aluminum bodied 10CA is the right family of connector.
3) Is the Blackburn 10CA a UL listed connector for inspected work?
It carries UL file E9809, so it goes in as a listed mechanical connector on inspected commercial and multi-family work. Mechanical connector is the category, meaning it is torqued down with a wrench, no crimp tool or die set needed.
4) What is the spacer on the 10CA split bolt for?
The 10CA ships as a split bolt with spacer. The spacer sits between the two conductors inside the bolt so the run and tap are kept apart and pressure is applied evenly, which is what you want when you are splicing dissimilar metals or conductors of different sizes. Order it as supplied, the spacer is part of the connector, not an extra.
5) Do I need a crimper or hydraulic tool to install a 10CA split bolt?
No tooling beyond a wrench. It is a mechanical connector, so the splice is made by tightening the bolt down on the conductors with the spacer between them. That is why split bolts are common for field taps and repairs where dragging a hydraulic crimper into a panel or handhole is not practical. Tape or an insulating cover is still required after the splice; it is not supplied with the connector.
6) Is the Blackburn 10CA sold individually or in a box?
Priced and sold each, so you can buy the exact count a job needs rather than a carton. The part number to quote is 10CA.
7) What is the country of origin on the Blackburn 10CA for a government or institutional submittal?
Manufactured in Mexico. That is the origin to put on procurement paperwork where a country-of-origin declaration is required on the connector line item.
