Blackburn ADR11-34 – Frequently Asked Questions
1) Can the Blackburn ADR11-34 connector be used on copper as well as aluminum conductors?
The ADR11-34 is a dual-rated mechanical connector, so it takes both copper and aluminum conductors. The body is aluminum with a tin plating, which is what lets it land aluminum without the galvanic problem a bare copper lug would create. It is UL listed under file E9809.
2) How many conductors does the Blackburn ADR11-34 terminate, and what wire range?
Three conductors, in a range of 1/0 through 14 AWG. That makes it a three-pole block for a small service or feeder tap where you need three separate ports rather than a single lug.
3) How does the ADR11-34 mount, and what hardware does it need?
It is a four-hole mount block with 3/8 inch spacing between the mounting positions. Pick up the screws or studs to suit your panel or enclosure; they are not part of the connector itself. Sold each, so order one per mounting position you are filling.
4) Is a mechanical connector like the Blackburn ADR11-34 the right choice, or should I use a compression lug?
A mechanical connector like the ADR11-34 is torqued down on the conductor with a setscrew, so you need no crimp tool and you can re-terminate or re-land a conductor in the field. Compression lugs need a die-matched crimper and are one-shot, but they take up less room. For panel and enclosure work where conductors may change, the mechanical block is the practical pick, and this one covers 1/0 down to 14 AWG in three ports.
5) Will the ADR11-34 accept a 14 AWG ground or control conductor without damaging it?
Yes, 14 AWG is the bottom of the stated range on this block, so the smallest port setting is rated to take it. The top end is 1/0, which means you can mix a heavy feeder conductor and small conductors across the three ports within the one connector.
6) What is the exact part number and origin on the Blackburn three-conductor tin-plated block?
Order it as Blackburn ADR11-34. It is made in Mexico and ships as a single piece.
7) Does the tin plating on the ADR11-34 matter for a damp or outdoor enclosure?
Tin plating over the aluminum body slows oxidation on the contact surfaces, which is why these blocks hold torque better than bare aluminum in humid or corrosive locations. It does not make the connector weatherproof on its own, so it still belongs inside a rated enclosure.
