Blackburn ADR25-34 – Frequently Asked Questions
1) Can the Blackburn ADR25-34 be used on copper conductors, or aluminum only?
Both. The ADR25-34 is a dual-rated mechanical connector, which means it is rated for aluminum and copper conductors. The body is aluminum with a tin-plated finish, which is what allows copper to be landed on it without the dissimilar-metal problem you get with bare aluminum.
2) How many conductors does the Blackburn ADR25-34 lug take, and what wire range?
Three conductors, per the model description: 250 kcmil down to 6 AWG stranded. That makes it a three-barrel tap or distribution connector rather than a single-conductor lug, so one connector lands three runs off the same pad.
3) What is the mounting pattern on the ADR25-34 connector?
It is a four-hole mount, so the base bolts down to a bus bar, ground bar or equipment pad with a four-bolt pattern rather than a single stud. That gives more mechanical hold and a larger contact footprint than a one-hole lug for the same conductor range.
4) Is the Blackburn ADR25-34 UL listed?
Yes, it carries UL file E9809. That is the reference an inspector or spec reviewer will want when the connector is landed in a panel, switchgear or service equipment.
5) Is this a compression lug or a mechanical set-screw connector?
Mechanical. The ADR25-34 uses set screws to clamp the conductor, so it installs with a hex key or torque wrench and no crimp tool, hydraulic head or dies. If your spec calls for compression terminations, this is not the right part.
6) Will a 6 AWG stranded ground land properly in a 250 kcmil rated connector like this?
Yes. The ADR25-34 barrels are rated over the full 250 kcmil to 6 AWG stranded range, so a small conductor at the bottom of the range is a listed use, not an improvised one. Each of the three ports can take a different size within that range.
7) Does the Blackburn ADR25-34 come as a single piece or in a multi-pack?
It is sold each, one connector per unit, under manufacturer part number ADR25-34. Order the count you need for the job rather than by box.
8) Where is the Blackburn ADR25-34 made?
Mexico. That matters on jobs with domestic-sourcing or country-of-origin reporting requirements, so confirm it against your submittal before it goes on a federally funded project.
