Blackburn 10NPW – Frequently Asked Questions
1) What wire sizes does the Blackburn 10NPW service entrance connector take?
The Blackburn 10NPW is built for 14 through 10 AWG conductors, and it takes two conductors in the connector. It's a mechanical set screw style connector, not a compression or crimp fitting, so you make the joint with a screwdriver or hex driver rather than a crimp tool.
2) Does the 10NPW connector come insulated, or do I have to tape or boot it?
It ships bare, with no enclosure or cover of any kind. On an exposed splice you supply the insulation yourself, whether that's a snap-on cover, heat shrink, or tape build-up to the voltage you're working at.
3) What voltage is the Blackburn 10NPW rated for, and is it UL listed?
Rated to 35 kV, and it carries UL file E9809. The 35 kV rating covers it for typical 600 V service entrance and secondary work with a lot of margin, and the UL file is the number an inspector or spec reviewer will want.
4) Is the 10NPW connector copper or aluminum, and can I use it on aluminum conductors?
Body is copper alloy with a tin plated finish. Tin plating is what makes a copper body suitable for use on aluminum as well as copper, which is why these show up on mixed-metal service entrance work. Nothing in the 10NPW spec restricts it to copper only, and the plating is the reason.
5) How big is the 10NPW body? I need it to fit inside a meter socket without crowding the other lugs.
The connector measures 9/32 inch outside diameter, so it's a small-barrel splice. That's what lets it sit in a crowded meter socket, a service entrance head, or a shallow gutter where a larger tap connector would foul the cover or the adjacent conductors.
6) Should I use a mechanical connector like the 10NPW or a compression splice on 14-10 service conductors?
Go mechanical when you don't want to carry a crimp die set to the job or when the splice may need to be opened later, which is the case on most meter and panel work. The 10NPW is a mechanical connector, so it's made and unmade with a driver. Compression is the choice where the joint has to be permanent and tamper-resistant, or where the spec calls out a compression connector by name.
7) I need the exact part number to match what's already in my panels. What is it?
Blackburn 10NPW is the manufacturer part number, ordered as a single model with no finish or size options to choose. If the connectors already in your panels are stamped 10NPW, this is the same part, and standardizing on it keeps one wire range (14-10) and one driver size across the fleet.
8) Is the 10NPW sold individually or in a bag quantity?
Sold each, one connector per unit, so you can buy the exact count a job needs rather than a carton. It's also made in the United States, which matters if you're supplying a job with domestic-content requirements.
