Blackburn ADR50-34 – Frequently Asked Questions
1) Can the Blackburn ADR50-34 be used on both copper and aluminum conductors?
Yes. The ADR50-34 is a dual-rated mechanical connector, meaning it is rated for both copper and aluminum conductors. The tin-plated aluminum body is what makes that dual rating possible: tin plating over an aluminum body prevents the galvanic issues you get when bare copper contacts bare aluminum. It is UL listed under file E9809.
2) How many conductors does the Blackburn ADR50-34 terminate, and what wire range?
Three conductors, with a range of 4 AWG through 500 kcmil stranded. So one ADR50-34 handles three separate runs in that range, which is why electricians reach for it on three-phase taps and multi-tap distribution rather than using three individual single-port lugs.
3) Will the ADR50-34 accept a 2/0 or 4/0 aluminum feeder?
Yes on both. The wire range runs 4 AWG to 500 kcmil stranded, and 2/0 and 4/0 sit inside that window. Because the connector is dual-rated, aluminum feeders are fine in it, not just copper.
4) How does the ADR50-34 mount to a panel or bus?
It is a four-hole mount connector, so it bolts down through four fixing points rather than a single stud. Four-hole mounting is what you want when the body is carrying three large conductors, since it resists the rotational load a single-bolt lug would take from a 500 kcmil cable. Confirm your panel pad or bus bar has matching four-hole prep before ordering.
5) Do I need a compression tool or crimper to install the ADR50-34?
No. This is a mechanical connector, so the conductors are secured with set screws and the only tool needed is the correct hex key or driver plus a torque wrench to hit the marked torque value. That is the practical advantage over a compression lug on service work, where hauling a hydraulic crimper and matching dies into a panel is not always realistic.
6) Is the ADR50-34 sold as a single piece or in a multi-pack?
Each. The selling unit is one connector, so order the count you need rather than working in box quantities. The manufacturer part number is ADR50-34.
7) Where is the Blackburn ADR50-34 made? I have a domestic sourcing requirement on a public job.
Country of origin is Mexico. If your project carries a Buy American or domestic-content clause on electrical materials, this part will not satisfy it and you will need to source a domestically manufactured equivalent.
