Blackburn ADR21-B2-5 – Frequently Asked Questions

1) What wire range does the Blackburn ADR21-B2-5 connector take?
The ADR21-B2-5 is rated for conductors from 2/0 stranded down to 14 AWG, so it covers a wide span of branch and feeder sizes with one part. If your conductor falls outside that window, on either end, you need a different catalog number.
2) Can I use the Blackburn ADR21-B2-5 on aluminum conductors as well as copper?
Yes. It is a dual-rated mechanical connector, which in the trade means the connector is listed for both aluminum and copper conductors, including AL to CU combinations. Standard practice still applies on the aluminum side: wire brush the conductor and apply an oxide inhibitor before landing it.
3) How many wires does the Blackburn ADR21-B2-5 connector hold?
One. It is a single-conductor mechanical connector, so it lands one wire per port. For splicing two or more conductors together in a box or a gutter, you want a multi-port or multi-tap connector body instead of this one.
4) Do I need a torque wrench for the Blackburn ADR21-B2-5, or is it a set-screw connector?
It is a mechanical set-screw type connector, not a compression lug, so no hydraulic crimp tool or dies are required. It is tightened with a hex driver to the torque marked on the connector or its packaging, which is what lets it be installed and re-terminated in the field.
5) Is the Blackburn ADR21-B2-5 sold individually or in a bag of two?
It is sold each. The part description references a 2-per-bag pack from the manufacturer, but the selling unit at order level is a single connector, so quantity 2 gets you two connectors.
6) Where is the Blackburn ADR21-B2-5 connector made?
Mexico. That matters for buyers with domestic-content or country-of-origin reporting requirements on a project submittal, so it is worth capturing at the order stage rather than at closeout.
