Blackburn ADR11-21-B2-5 – Frequently Asked Questions
1) What wire range does the Blackburn ADR11-21-B2-5 connector take?
The ADR11-21-B2-5 is built for a 1/0 stranded through 14 AWG range, which is the span called out in its part description (CONN-2CONDCTR-1/0STR-14AWG-2BG). That covers everything from a service-size 1/0 conductor down to 14 AWG control or branch wire in the same connector, so you can land mixed sizes on a single device instead of stocking two.
2) Can I use this Blackburn mechanical connector on aluminum conductors as well as copper?
Yes. It is a dual-rated mechanical connector, and dual-rated (AL9CU) means the connector body is approved for aluminum and copper, including aluminum-to-copper combinations in the same connector. That is why these get spec'd on service and feeder work where an aluminum feeder terminates onto copper branch wire.
3) How many conductors does the ADR11-21-B2-5 accept?
Two. It is a 2-conductor connector, so it lands one wire per port in a two-port body. If you need to gather three or more conductors at one point, you need a larger multi-port connector or a separate tap for each pair, not this one.
4) Do I need a crimp tool or die set to install this Blackburn connector?
No crimping gear. This is a mechanical connector, so it is tightened down with set screws using a hex key or driver, not compressed with a hydraulic tool and dies. That makes it the practical choice for service calls and retrofit splices where hauling a crimper into a panel is not worth it, and it means the joint can be opened and re-terminated later.
5) What is the exact manufacturer part number for this two-conductor Blackburn connector?
Blackburn ADR11-21-B2-5. That is the number to quote or cross when you want this specific 2-conductor, 1/0 stranded to 14 AWG dual-rated mechanical connector rather than an adjacent range in the ADR family.
6) Is the Blackburn ADR11-21-B2-5 sold individually or as a multi-pack?
It is sold each, so the quantity you order is the number of connectors you get. The part code ends in B2 for the two-port configuration with a bagged presentation, but for ordering purposes the selling unit is a single connector.
7) Where is the Blackburn ADR11-21-B2-5 connector made?
Mexico. For federal, state, or institutional jobs carrying domestic-sourcing language, that is the country of origin to put on your submittal for this connector.
