Blackburn ADR60-21AR – Frequently Asked Questions
1) What is the Blackburn ADR60-21AR connector used for?
The ADR60-21AR is a two-conductor anti-rotational mechanical connector, one-hole mount, made of aluminum with a tin-plated finish. Anti-rotational means the body is keyed so it will not spin on the mounting bolt when you torque the setscrews, which is what you want when landing two conductors on a single-hole pad or bus. It is UL listed under file E9809 and sold each.
2) Can I use an aluminum connector like the ADR60-21AR on copper conductors?
The ADR60-21AR body is aluminum with a tin plating, and tin-plated aluminum mechanical connectors are the standard dual-rated choice for terminating copper, aluminum, or a mix of the two. The plating is what keeps the aluminum body from galvanic attack against copper. Always confirm the conductor range stamped on the body matches the cable you are landing.
3) What does the 1/2 inch spacing on the ADR60-21AR mean for my mounting pad?
Conductor spacing on the ADR60-21AR is 1/2 inch, so the two conductor barrels sit half an inch apart on center. That sets how much clearance you need between the landed cables and any adjacent phase or enclosure wall. Since it is a single-hole mount, you only need one tapped or drilled hole in the pad, not a two-bolt NEMA pattern.
4) Is the Blackburn ADR60-21AR UL listed for use in a service or panel installation?
Yes. The ADR60-21AR carries UL listing under file E9809, which is what an inspector or a hospital or school MRO spec will be looking for on a mechanical grounding or splice connector. No other rating is claimed for it.
5) Do I need an anti-rotational connector or will a standard two-conductor lug do?
Use the anti-rotational version, like the ADR60-21AR, any time the connector lands on a single bolt. With one mounting hole there is nothing to stop a plain lug from twisting as you tighten the conductor setscrews, which loosens the pad connection. A two-hole lug on a NEMA-drilled pad is held against rotation by the second bolt, so the anti-rotational feature buys you nothing there.
6) How is the ADR60-21AR sold, and what part number do I order?
Order it as Blackburn part ADR60-21AR. It is sold as a single piece, each, not in a bag or carton quantity, so the count you order is the count you get. Country of origin is Mexico.
