Blackburn 2B350 – Frequently Asked Questions
1) What conductor sizes does the Blackburn 2B350 two-bolt connector take?
The Blackburn 2B350 is sized for copper conductors from 4/0 AWG through 350 kcmil. If your run is smaller than 4/0 or larger than 350 kcmil, this is the wrong body size and you need the adjacent catalog number in the 2B series.
2) Is the Blackburn 2B350 connector copper or aluminum bodied, and can I use it on aluminum cable?
It is a copper-bodied mechanical connector, so use it on copper conductors. For aluminum or AL/CU-rated splices you want a dual-rated aluminum-bodied connector instead, not this one.
3) Does the 2B350 come with a spacer for splicing two conductors?
No. The 2B350 is the version supplied without a spacer, which is how it is normally used for a straight tap or termination onto a bus or single conductor. If you are splicing two cables end to end and the application calls for a separator between them, order the spacer-equipped version of the same connector.
4) Do I need a crimp tool or die set for the Blackburn 2B350?
No special tooling. This is a mechanical bolted connector, not a compression lug, so it goes on with a wrench and is field-serviceable if the conductor ever has to come off. Compression connectors in the same size range need a matched die and hydraulic tool.
5) Is the 2B350 sold individually or in a box?
It is sold each, so quantity ordered equals the number of connectors you receive. Plan one per termination point when you are pulling a count for a job.
