Nonmetallic cable splice and tap
October 27, 2003 — Nonmetallic (NM) splice and tap technology connects 12 AWG and 14 AWG circuits using NM cable. It eliminates the need for junction boxes, covers, fittings, and wire nuts. It's approved for use in a variety of applications, including residential branch circuits, manufactured housing, and pre-fabricated building structures. When adding new circuits in residential applications, NM connectors eliminate the need to cut into the existing wiring and the extra junction boxes and associated hardware required for the tap connection.
