Blackburn ADR31-32 – Frequently Asked Questions

1) Can the Blackburn ADR31-32 connector be used on both copper and aluminum conductors?
Yes. The ADR31-32 is a dual-rated mechanical connector, which is the industry term for a connector listed for use with both copper and aluminum conductors. The body itself is aluminum with a tin-plated finish, which is what allows it to be used on copper without the galvanic issues bare aluminum would create.
2) How many wires can I land in a Blackburn ADR31-32 lug?
Three. The ADR31-32 is a 3-conductor mechanical connector, so you can terminate three separate runs in the single body rather than stacking multiple single-barrel lugs on one pad. If you need more than three, step up to a higher conductor-count mechanical connector.
3) Is the Blackburn ADR31-32 UL listed for code compliance on a commercial job?
The ADR31-32 carries UL file E9809, which is the listing an inspector will look for on a mechanical connector used in commercial building wiring, distribution equipment, or control panel work. Blackburn is the brand of record on the part and ADR31-32 is the manufacturer part number to cite on submittals.
4) Does the tin plating on this aluminum lug matter if I'm landing copper feeders?
It does. Tin plating over the aluminum body is what makes the ADR31-32 suitable for copper conductors, since it separates dissimilar metals at the contact surface and resists corrosion in the joint over time. That plating is also why the connector holds up in damp or corrosive panel environments better than a bare aluminum lug.
5) Do I need a crimp tool or die set to install the Blackburn ADR31-32?
No crimping gear needed. This is a mechanical connector, meaning the conductors are secured with set screws and torqued down with a hex key or driver, not compressed with a hydraulic or battery crimper. That makes it practical for service and repair work where nobody wants to haul dies to the panel.
6) Can I use this connector inside an industrial control panel, or is it only for distribution gear?
Both. The ADR31-32 is used in residential and commercial building wiring, industrial control panels, and electrical distribution equipment. The deciding factors on the job are conductor count (three) and the fact that it is dual-rated, so the same part works whether the feeders coming into the panel are copper or aluminum.
7) Where is the Blackburn ADR31-32 manufactured, and what UPC should I match against my order?
The ADR31-32 is manufactured in Mexico. For receiving and cross-referencing, the part number is ADR31-32 and the UPC on the carton is 783786610174.
