Blackburn 2B500PW – Frequently Asked Questions
1) Can I use an aluminum two-bolt connector like the Blackburn 2B500PW on copper conductors?
The 2B500PW body is aluminum, and Blackburn's aluminum mechanical connectors of this style are made for aluminum-to-aluminum and aluminum-to-copper connections when used with an oxide inhibitor. It carries UL file E9809. Match the UL listing marking on the part to the conductor combination you are actually landing.
2) Is the Blackburn 2B500PW UL listed?
Yes, it carries UL file number E9809, which is the listing an inspector or a spec on the drawing will be looking for on an aluminum mechanical connector.
3) What is the 3/4 inch dimension on the Blackburn 2B500PW connector?
3/4 inch is the outside diameter called out in the spec, and it matches the "3/4B" in the part description (the bolt/bar reference). Use that figure when you are checking clearance inside a pedestal, handhole or enclosure where the tap has to sit.
4) Does the Blackburn 2B500PW come with the spacer, or is that ordered separately?
The spacer is part of the connector. The "W/SPCR" in the part description means it ships with the spacer installed, which is what lets the same body accept the smaller end of the 397.5 MCM to 4 AWG range without the conductor floating in the barrel.
5) Is a two-bolt connector the right choice, or should I use a compression lug?
A two-bolt mechanical connector like the 2B500PW is the choice when you need a field-serviceable connection with no crimp tooling, and it is the usual answer for utility taps, service entrances and pad-mount work where crews may need to break the connection later. Compression lugs are the better call when the connection is permanent and you have the die tooling on site. This one is a mechanical connector, not a compression fitting.
6) How is the Blackburn 2B500PW sold, individually or in a box?
It is sold each, so one order quantity equals one connector. Count your taps per structure and order accordingly, since a two-bolt tap connection typically needs one connector per conductor pair.
7) Where is the Blackburn 2B500PW connector manufactured?
Blackburn lists country of origin for the 2B500PW as United States and India. That matters on public jobs where a domestic-preference clause is in the contract, so confirm the marking on the parts you receive against your project requirement.
