Blackburn ADR25 – Frequently Asked Questions

1) Can the Blackburn ADR25 connector be used on both copper and aluminum conductors?
Yes. The ADR25 is a dual-rated mechanical connector, meaning it is rated for both copper and aluminum conductors. The body itself is aluminum with a tin-plated finish, which is what makes the dual rating possible: the tin plating keeps the aluminum body from reacting directly with a copper conductor. On aluminum conductors you still follow normal practice for wire brushing and oxide inhibitor.
2) What wire size range does the Blackburn ADR25 take?
The ADR25 is built for a single conductor from 250 kcmil down to 6 AWG stranded. One conductor per connector, so if you are landing two cables you need two connectors or a two-conductor body.
3) Is the ADR25 a one-hole or two-hole lug?
One hole. The ADR25 mounts with a single bolt, which is the common pattern for panelboard neutral and ground bars, transformer lugs, and equipment pads that only have one tapped hole. If your bus pad is drilled on NEMA two-hole centers and the spec calls for two-hole terminations, this is not the right body.
4) Is the Blackburn ADR25 UL listed for electrical panel work?
Yes, it carries UL file E9809. That covers it for the code-compliant terminations electrical contractors and facility MRO crews make in panels, control gear, and utility distribution equipment.
5) Does the ADR25 connector come insulated or do I need to cover it?
It ships bare. The ADR25 has no insulation on it, so where the installation calls for an insulated termination you add heat shrink, a boot, or a cover separately. In a panel or on a bus bar inside enclosed gear, bare is normally what the job wants.
6) Will a tin-plated aluminum lug hold up in a damp or corrosive environment?
The tin plating on the ADR25 is what buys you corrosion resistance; bare aluminum oxidizes at the contact surface and the plating slows that down while keeping contact resistance low. It is a reasonable choice for exterior gear, pump rooms, and utility cabinets. For direct burial or continuous immersion, that is a different product class.
7) What is the exact part number and who makes the ADR25 connector?
Blackburn ADR25 is the manufacturer part number, no suffix. Distributors will sometimes see it described as AL 1 CNDTR 1 HOLE MOUNT 250-6 STR TP, which is the same item. It is made in Mexico.
