Blackburn ADR25-44 – Frequently Asked Questions

1) Can the Blackburn ADR25-44 connector be used on both copper and aluminum conductors?
Yes. The ADR25-44 is a dual-rated mechanical connector, meaning it is rated for use with both aluminum and copper conductors. The body is aluminum with a tin-plated finish, which is what makes the copper connection acceptable and keeps the aluminum-to-copper interface from corroding. Dual-rated is often marked AL9CU in the field.
2) How many wires can I land in the Blackburn ADR25-44?
Four. The ADR25-44 is a 4-conductor connector, so you get four separate ports for tap or feeder conductors in one body, which saves space in a panel or pull box compared to running multiple single-port lugs.
3) What wire range does the Blackburn ADR25-44 accept?
The ADR25-44 is a 250 to 6 stranded range connector, so it will take conductors from 250 kcmil down to 6 AWG stranded in each of its four ports.
4) How does the ADR25-44 mount, and do I need a separate mounting kit?
It is a 4-hole mount connector, so the body bolts down through four holes to a panel, ground bar pad, or equipment surface. You supply the hardware that suits the pad pattern and the enclosure; the connector itself is sold each, not as a kit.
5) Should I use a mechanical connector like the ADR25-44 or a compression lug?
A mechanical connector like the ADR25-44 tightens onto the conductor with set screws, so no dies or hydraulic crimper are needed and it can be re-terminated or re-tapped later. Compression lugs need matched dies and tooling and are a permanent termination. For panel and distribution work where taps may change, or where you are mixing copper and aluminum on the same block, the dual-rated mechanical connector is the practical choice.
6) Will the tin plating on this Blackburn connector hold up in a damp or outdoor enclosure?
The tin-plated surface on the aluminum body is there specifically for corrosion resistance and to keep contact resistance low over time, which is why it is used in utility distribution and industrial enclosures. For direct aluminum conductor terminations, standard practice is still to use an oxide-inhibiting joint compound on the conductor.
7) What is the exact part number and origin for ordering the Blackburn 4-conductor connector?
Order Blackburn part number ADR25-44. It is sold as each, and country of origin is Mexico, which matters if you are filing origin documentation on a government or institutional job.
