Blackburn 2B20PW – Frequently Asked Questions
1) Can I use the 2B20PW aluminum connector on copper conductors?
The 2B20PW body is aluminum, and Blackburn aluminum mechanical connectors in this family are AL9CU rated for both aluminum and copper conductors. It carries UL file E9809. Where you are landing aluminum, use an oxide-inhibiting compound on the conductor as the job spec requires.
2) What is the 1/2 inch dimension on the Blackburn 2B20PW?
1/2 inch is the outside diameter called out for the 2B20PW, matching the "1/2B" in the part description. That is the mounting bolt/stud opening size, so it lands on a 1/2 inch bolt or bus stud.
3) What does the spacer on the 2B20PW do?
The 2B20PW is supplied with a spacer (the "W/SPCR" in the part name). On a two-bolt connector the spacer takes up the gap when you are landing a conductor at the smaller end of the 2/0 to 6 AWG range, so the clamp closes evenly and the bolts torque properly instead of racking the body.
4) Is the Blackburn 2B20PW UL listed for electrical work?
Yes. The 2B20PW carries UL file E9809 as a mechanical connector, which is what an inspector will look for on a service or panel termination.
5) Is the 2B20PW sold individually or in a box?
It is sold each, so quantity one gets you one connector with its spacer. Count your terminations and order accordingly, including any spares for the panel.
