NSi NMS Non-Metallic Splice Kit, 12-14 AWG, 2- or 3-Conductor with Ground

The NSi NMS Non-Metallic Splice Kit is built for splicing 12 or 14 AWG solid conductor cable, giving electricians a fast, code-compliant way to join branch-circuit wiring. This splice kit is available in 2-Conductor and 3-Conductor with ground configurations, so installers can select the conductor count that matches the branch-circuit application at hand while relying on the same dependable, non-metallic housing across the line. Constructed with a hinged cover for quick, easy termination, this kit is approved for a range of applications including residential branch circuits, manufactured housing, and pre-fabricated building structures. It's a practical, reliable solution wherever solid-conductor splicing is required, and the shared design and approvals carry through both the 2-Conductor and 3-Conductor with ground options.

Key Features

  • Conductor Compatibility: Designed for 12 or 14 AWG solid conductor wire.
  • Configuration Range: Available in 2-Conductor or 3-Conductor cable with ground for complete circuit connections, letting you match the kit to the specific branch-circuit wiring in the box.
  • Hinged Cover Design: Allows for fast, easy termination during installation, reducing time spent on each splice.
  • Non-Metallic Construction: Durable non-metallic housing suited for branch-circuit splicing applications across both conductor configurations.
  • Broad Approval Range: Approved for residential branch circuits, manufactured housing, and pre-fabricated building structures.
  • Consistent Design Across Options: Both the 2-Conductor and 3-Conductor with ground versions share the same hinged-cover housing and approval scope, simplifying stocking and specification.

NSi NSINMS-2 – Frequently Asked Questions

1) What wire size does the NSi NMS non-metallic splice kit work with?
The NSi non-metallic splice kit is built for 12 or 14 AWG solid conductor wire. It is not intended for stranded conductor. If your branch circuit is 12-2 or 14-2 or 12-3 or 14-3 NM cable with a ground, this is the size range it covers.
2) What is the difference between the NSi NMS-2 and NMS-3 splice kits?
The difference is conductor count. The NMS-2 splices 2-conductor cable with ground, and the NMS-3 splices 3-conductor cable with ground. Both cover the same 12 or 14 AWG solid conductor range. Pick by the cable in the wall: a 14-2 with ground run takes the NMS-2, a 14-3 with ground run (a travelers-in-a-three-way or a switched-plus-constant run) takes the NMS-3.
3) Can I use the NSi splice kit on stranded THHN in conduit?
No. The NSi NMS splice kit is specified for solid conductor only, 12 or 14 AWG, and the approvals it carries are for residential branch circuits, manufactured housing, and pre-fabricated building structures. Stranded feeder or conduit work is outside what it is built for; use a junction box and connectors rated for stranded conductor instead.
4) Is the NSi NMS splice kit approved for manufactured housing?
Yes. Approved applications include residential branch circuits, manufactured housing, and pre-fabricated building structures. That makes it a common choice for modular and panelized construction where factory-run cable has to be joined on site.
5) Does a splice kit like this let me splice without a junction box?
The NSi NMS kit is a self-contained non-metallic splice enclosure with a hinged cover, made to terminate a cable splice in one piece rather than pulling a separate box, cover and connectors. It replaces the box-and-wirenut assembly for 12 and 14 AWG solid branch-circuit splicing in the applications it is approved for. Final placement and accessibility still follow your local code.
6) Will the NSi splice kit handle a 20 amp circuit?
It accepts 12 AWG solid conductor, which is the conductor size used on a standard 20 amp residential branch circuit, and 14 AWG solid for 15 amp circuits. Both are within its stated range.
7) What does the hinged cover on the NSi splice kit actually do for install time?
The cover stays attached to the body, so there is no loose lid to hold, drop or hunt for on a ladder. You land the conductors, close the cover and you are done. For a builder running dozens of splices in a manufactured-housing package, that is the whole reason to buy this over a box and wirenuts.
8) Is the NSi NMS splice kit made in the USA?
Yes, country of origin on the NSi NMS non-metallic splice kit is the USA. That matters on public and institutional jobs carrying domestic-sourcing requirements.
