Blackburn ADR35-21AR – Frequently Asked Questions
1) What wire range does the Blackburn ADR35-21AR connector take?
The ADR35-21AR is a 350-6 connector, meaning it accepts conductors from 350 kcmil down to 6 AWG in each of its two ports. That range covers most service entrance and feeder taps on a panel or meter can.
2) What size mounting bolt does the Blackburn ADR35-21AR need?
It is a one hole mount lug with 3/8 inch bolt spacing, so it lands on a single 3/8 inch stud or bolt on the busbar or ground bar.
3) Can I use the Blackburn ADR35-21AR on copper conductors as well as aluminum?
The body is aluminum with a tin plating, which is the standard AL9CU style construction used for both aluminum and copper conductors. The tin plate is what keeps the aluminum body from reacting against copper wire. Use an oxide inhibitor on aluminum conductors as the installation normally calls for.
4) Do I need a crimp tool for the Blackburn ADR35-21AR?
No. This is a mechanical connector, so the conductors are clamped by setscrews. All you need is the correct hex key or socket and a torque wrench to hit the marked torque value. No hydraulic crimper or die set involved.
5) How many wires can land in one Blackburn ADR35-21AR?
Two. It is a two conductor lug, so you get two separate ports each taking 350 kcmil to 6 AWG. If you have more than two taps at the same point, you need a larger multi-port connector or a second lug position.
6) Does the Blackburn ADR35-21AR come as a single lug or in a bag?
It is sold each, so one lug per order. For a multi-tap panel or a ground bar with several feeders, order the count you need.
