Blackburn ADR35-21 – Frequently Asked Questions

1) Can the Blackburn ADR35-21 connector be used on both copper and aluminum conductors?
Yes. The ADR35-21 is a dual-rated mechanical connector, so it is rated for both copper and aluminum conductors. The body itself is aluminum with a tin-plated finish, which is what allows it to be used on copper without a dissimilar-metal problem at the contact surface.
2) What wire sizes will the ADR35-21 take?
It accepts stranded conductors from 6 AWG up to 350 MCM, with two ports. That range covers most feeder and service work, from small branch feeders up through 350 MCM service conductors.
3) How many wires can I land in one Blackburn ADR35-21?
Two. It is a 2-conductor block, one wire per port, with 1/2 inch spacing between the ports for clearance between the terminations. If you need to land three or more conductors at one point you need a larger multi-port block, not this one.
4) How does the ADR35-21 mount inside a panel or enclosure?
Single-hole mount. One fastener through the base secures it to a panel, enclosure wall, or mounting bracket, so you only need one drilled and tapped hole rather than a two-bolt footprint.
5) Is a dual-rated mechanical connector the right choice, or should I be using a compression lug?
A mechanical connector like the ADR35-21 is set with a set screw and a wrench, so it can be installed and re-terminated with hand tools and no crimper or die set. That is what makes it the usual pick for panel taps, service splices, and MRO repairs where you may need to open the joint again. Compression lugs are the choice where a permanent, tool-verified crimp is specified. Because this one is dual-rated, the same part covers both copper and aluminum runs, so you can stock one connector instead of two.
6) Will a tin-plated aluminum connector hold up in a damp or outdoor service enclosure?
The tin plating over the aluminum body is there for corrosion resistance and stable contact at the conductor surface, which is why this style is common in utility service and outdoor distribution gear. As with any aluminum termination, use the appropriate joint compound and torque practice for the conductor you are landing.
7) Is the ADR35-21 sold individually or in a pack?
Each. The selling unit is one connector, model ADR35-21, so order the exact count you need rather than a multi-pack.
