Blackburn ADR80-21 – Frequently Asked Questions
1) Can the Blackburn ADR80-21 be used on copper as well as aluminum conductors?
Yes. The ADR80-21 is a dual-rated mechanical connector, so it is rated for both aluminum and copper conductors. The body is aluminum with a tin-plated finish, which is what allows it to be used on copper without the galvanic problems a bare aluminum lug would create.
2) What wire size range does the Blackburn ADR80-21 take?
The ADR80-21 is built for large conductors in the 300 through 800 range, and it accepts two conductors in that range. If your feeders are smaller than 300, this is the wrong lug and you need a smaller-range dual-rated connector.
3) How does the ADR80-21 mount to a bus or panel?
It is a one-hole mount lug, so it lands on a single bolt at the bus bar, panel pad, or equipment terminal. One-hole mounting means the connector can rotate on the bolt until it is torqued, so watch conductor alignment and clearance to adjacent phases when you set it. If the equipment pad is drilled for two-hole NEMA spacing, this body will not match that prep.
4) Can I use the ADR80-21 to parallel two feeders into one terminal?
That is exactly the arrangement it is made for. The two-conductor barrel lets you land a pair of 300 to 800 conductors and bring them to a single bolted connection point. Both conductors should be the same size and the same metal per the connector's listing, and each conductor gets its own set screw torqued to the value marked on the body.
5) Is the Blackburn ADR80-21 UL listed?
Yes, it carries UL file E9809. That is the reference an inspector or spec reviewer will want for a dual-rated mechanical connector on a service or feeder termination.
6) Is the ADR80-21 a compression lug or a set screw lug?
Mechanical, not compression. It clamps the conductor with set screws, so no hydraulic crimper or die set is needed, just a torque wrench or hex key. For property maintenance and service work that is the practical advantage: a failed termination can be backed out and redone in place.
7) Do I get one lug or a pair when I order the ADR80-21?
Pricing and packing are per each, so one connector ships per unit ordered. A two-conductor lug still terminates only into one mounting point, so a three-phase set of taps means ordering multiples.
8) Where is the Blackburn ADR80-21 made?
Manufactured in Mexico. Buyers working under domestic-preference procurement rules should flag that before submitting it on a federal or state-funded job.
