Blackburn ADR11-21 – Frequently Asked Questions

1) Can the Blackburn ADR11-21 connector be used on copper as well as aluminum conductors?
Yes. The ADR11-21 is a dual-rated mechanical connector, which is the trade term for a lug rated AL9CU, so it accepts aluminum or copper conductors. The body itself is aluminum with a tin-plated finish, and the tin plating is what lets it sit against copper without the dissimilar-metal corrosion you would get from bare aluminum.
2) What wire sizes fit the Blackburn ADR11-21?
Each of the two ports takes conductors from 14 AWG up to 1/0 AWG, so you can land anything from a small branch-circuit conductor to a 1/0 feeder or grounding electrode conductor in the same lug. Nothing larger than 1/0 belongs in it.
3) How many conductors does the ADR11-21 terminate?
Two. It is a 2-conductor lug, so you get two separate wire ports under two set screws, which is what you want for a tap or a two-way splice rather than a multi-conductor neutral bar.
4) What does the 1/4 inch spacing on the ADR11-21 mean for mounting clearance?
The lug is built with 1/4 inch barrel spacing, which sets how far the conductor ports sit off the mounting surface and from each other. It is a single-hole mount connector, so plan for a 1/4 inch stand-off when you are checking clearance to the enclosure wall or an adjacent lug in a tight panel.
5) How is the ADR11-21 fastened to a bus or panel?
It is a one-hole mount lug, so it bolts down with a single fastener through the base pad. The bolt, washer, and any spacer are not part of the connector, so pick up mounting hardware sized to your bus hole separately.
6) How is the Blackburn ADR11-21 sold, individually or in packs?
Sold each. The part number to order is ADR11-21, so if you need one per phase plus a neutral on a three-phase job, count them out individually.
7) Will a tin-plated aluminum connector hold up in a damp or outdoor utility enclosure?
Tin plating over the aluminum body is there for corrosion resistance, which is why these show up on utility connection points and service entrance terminations. For aluminum conductors in a wet or corrosive location, still brush the strands and use a joint compound as the conductor manufacturer directs.
