Blackburn 2B350PW – Frequently Asked Questions
1) What conductor range does the Blackburn 2B350PW two-bolt connector accept?
The 2B350PW covers 350 kcmil down to #4, per the 350-4 range in the part description. It is a mechanical set screw style connector, so the conductor is clamped under bolt pressure rather than crimped.
2) Can I use this aluminum two-bolt connector on copper conductors, or aluminum only?
The body is aluminum and it is UL listed under file E9809. Aluminum-bodied Blackburn two-bolt connectors of this style are dual rated AL/CU, but confirm the AL9CU marking stamped on the part itself before terminating copper, since the rating is carried on the connector body marking.
3) What is the spacer on the 2B350PW for?
The W/SPCR in the part name means it ships with a spacer. On a two-bolt connector sized for 350 kcmil, the spacer takes up the extra barrel depth so smaller conductors in the range, down to #4, seat centered under the bolts instead of being clamped off to one side. Keep it in place for small conductors and remove it for the large end of the range.
4) Should I use a two-bolt mechanical connector or a compression lug for a 350 kcmil termination?
A two-bolt mechanical connector like the 2B350PW is the choice when you have no hydraulic crimp tool on site or you want a termination you can open and re-terminate later, and its 350-4 range means one part covers several conductor sizes. Compression lugs need a die and tool matched to the exact conductor and are permanent. For pull boxes, panel grounds and field splices where access and reuse matter, the mechanical connector is the practical pick.
5) Do I order the 2B350PW in packs or as single pieces?
Sold each. One 2B350PW connector with its spacer per unit, so order the piece count you need for the job rather than a box quantity.
6) What is the exact manufacturer part number and country of origin on this Blackburn connector?
Manufacturer part number is 2B350PW, made in India. That is the number to quote when matching an existing installation, since the PW suffix denotes the version supplied with the spacer.
