Blackburn 2B500 – Frequently Asked Questions
1) What conductor size range does the Blackburn 2B500 two-bolt connector take?
The 2B500 is built for 300 through 500 kcmil copper conductors, and it is supplied without a spacer, so it is intended for two conductors in that same size band rather than a wide range tap. If your run is smaller than 300 kcmil, this is the wrong body size and the connection will not bear properly.
2) Can I use a copper two-bolt connector like the Blackburn 2B500 on aluminum conductors?
No. The 2B500 body is copper and is listed for copper conductors only. For aluminum or for a mixed aluminum-to-copper splice you need a connector rated AL9CU or an aluminum-bodied mechanical connector in the matching size range.
3) What bolt size does the Blackburn 2B500 use, and do I need a special wrench?
It is a 3/4 bolt two-bolt connector, so it tightens with standard hex sockets, no proprietary tool. Both bolts should be pulled down evenly so the conductor seats flat in the channel rather than cocking to one side.
4) Does the Blackburn 2B500 come with a spacer, and when would I need one?
It ships without a spacer. Spacers are used when you are landing a conductor noticeably smaller than the connector's top size so it still clamps square. Since the 2B500 is a 300 to 500 body with no spacer supplied, plan on conductors sized within that band on both sides.
5) Is the Blackburn 2B500 sold individually or in a box?
It is sold each, so a quantity of one gets you a single connector. Order by the number of splices on the job, not by the pair.
6) What is the part number and country of origin on the Blackburn 2B500?
The manufacturer part number is 2B500 from Blackburn, and production is sourced from India and the United States. Distributors ordering to a spec should call it out by that MPN, since the size, bolt count, and no-spacer configuration are all baked into that number.
