NSi Industries Copper Split Bolt Connector, Tin Plated

The NSi Industries Copper Split Bolt Connector is an all-purpose splice and tap connector built with an electro-tinned copper body, engineered for a wire range of 6 AWG - 2 AWG and a wire diameter range of 0.128 - 0.316 IN. It is UL Listed to UL 486A-486B and UL 486D for copper and copperweld wires only, and each connector includes a nut, spacer, and pressure pad for a complete, ready-to-install kit. Dual rated for aluminum-to-copper use, this split bolt also handles aluminum-to-aluminum, steel-to-aluminum, copper-to-copper, and steel-to-copper combinations, making it a versatile choice for splice and tap connections on commercial and industrial electrical projects.

NSi N-2SP – Frequently Asked Questions

1) What wire sizes does the NSi N-2SP split bolt connector take?
The N-2SP handles 6 AWG through 2 AWG on both the main (line, primary, run) and the tap (load, secondary). Where the main and tap are the same size, the range runs 8 SOL to 2 STR. Conductor diameter has to fall between 0.128 and 0.316 inch, so check the actual conductor OD if you are splicing an odd strand count.
2) Can I tap a small conductor off a 2 AWG main with this split bolt?
Yes, down to 8 SOL. With one maximum-size main in the connector, the smallest copper tap the N-2SP is rated for is 8 solid. Anything smaller than that needs a different connector or a reducing arrangement.
3) Do I need to buy a separate nut or pressure pad for this split bolt?
No. Each N-2SP ships as a complete kit with the nut, spacer, and pressure pad, so there is nothing extra to order to make the splice. You will still want insulating tape or a split bolt cover, which is not part of the kit.
4) Can I use a split bolt for a grounding electrode or bonding connection?
Grounding and bonding is one of the stated applications for this NSi split bolt, and it is listed under UL 486A-486B and UL 486D. Keep the conductor within 6 AWG to 2 AWG and note it is listed for copper and copperweld only, which covers most grounding conductors and copperweld ground rods leads.
5) Split bolt or a mechanical set screw lug for tapping a feeder?
A split bolt like the N-2SP is for splicing two conductors together or tapping one off a run in free air inside a box or pull box, and it is rated 6 AWG to 2 AWG. A set screw lug is for landing a conductor on a bus, pad, or equipment terminal. If you are joining wire to wire, the split bolt is the right tool; if you are landing on a piece of gear, it is not.
6) Will a tin plated copper split bolt hold up in a damp or outdoor pull box?
The body is copper with an electro-tinned finish, which is there to slow corrosion on the connector itself. Tin plating is also what makes a copper connector suitable where dissimilar metals meet. It is a bare mechanical connector, so it still needs to be insulated and housed in an enclosure rated for the location.
7) What is the exact NSi part number for the 6 to 2 AWG copper split bolt?
N-2SP, from NSi's N-SP series of copper split bolt connectors. That is the number to quote for the tin-plated copper body covering 6 AWG through 2 AWG.
