Blackburn 2NPW CU TINPLT SERV ENTRANCE CONN 6-2

The 2NPW is a 6-2 connector, so it accepts conductors from #6 AWG through #2 AWG, with two conductor ports. It is a mechanical set-screw style connector, not a compression fitting, so you land the wire and torque the screw with hand tools rather than needing a crimper.

Copper only. The 2NPW is a tin plated copper alloy body rated for copper conductors in the 6-2 range. For aluminum or mixed copper/aluminum runs you need a connector specifically marked AL9CU, not this one.

It ships bare, with no enclosure or insulating cover. On a service entrance splice you finish it yourself, with tape, a shrink boot, or by making the connection inside a meter socket or enclosure where the splice is contained.

35 kV. That covers ordinary 120/240V residential and commercial service entrance work with a wide margin, and it also holds up for medium voltage splicing where the conductor size fits the 6-2 range.

The body outside diameter is 3/8 inch, so it is a compact barrel. Use that number to check clearance in a crowded meter socket or pull box before you commit, since the wire bend plus the connector is what actually fills the space.

For a two-conductor service entrance connection in the 6 to 2 AWG range, the 2NPW mechanical connector does the job with a wrench or screwdriver, no hydraulic crimper and no die set to match. Compression connectors are the better pick when you want a permanent, non-reusable joint or the spec calls out compression specifically. Mechanical is also the practical choice for field repairs and retrofits where you may need to open the joint later.

Order by part number 2NPW. The family runs across several wire ranges, and 2NPW is the 6-2 copper, tin plated version. If your conductors are larger than #2 or smaller than #6, it is a different number in the series, so match the AWG on both conductors before ordering.

Sold each, one connector per unit, so you order the exact count the job needs rather than buying a box. It is made in the United States.

Tin plating over the copper alloy body slows corrosion and, more importantly, keeps copper-to-copper contact surfaces from oxidizing into a high resistance joint. That matters on service entrance splices in damp meter bases and outdoor pull boxes where an untreated copper connector can dull and heat up over time.
