This code requirement is an important safety feature that protects the wiring . There are plastic push-in NM connectors made to install inside the box, such as the Raco Insider: This will install in a standard 1/2" KO. This is a very common problem, so connectors that will work with cables fished into boxes are available almost everywhere electrical supplies are sold.
Does anyone know of a romex connector that can be installed from the inside of an EXISTING junction box. I can't access the outside of the box without opening up the drywall, and the wires are coming in KO's without romex connectors. Also where are they available to be bought? Thanks for any help.
NM-cables must be securely fastened where they enter an electric panel, so that tugging on a cable from outside the box will not pull wires loose from their terminations inside. This is usually accomplished by installation of an NM-connector at the knockout that is secured to the box from both sides and clamps down on the cable.
You'll need a 3/4" snap-in NM clamp that can be installed from the inside of the box. You do need a NM clamp (vs a mere bushing) here, first off; a simple bushing does not provide the clamping of the cable jacket required by NEC 312.5(C) for .An insert clamps the cable in place and provides more strain relief than standard snap-in cord grips for building cable. Use to connect building cable for dry locations, also known as Romex type NM-B cable, to enclosures and outlet boxes by pushing these grips into a knockout. You’ll also need to install cable clamps in the metal box. These thread into the box from the outside. Plastic boxes have internal clamps. 2. Run Cables. Bring the cables into the box through the clamps.
Twin Screw Non-Metallic Cable Clamp Connectors to join non-metallic sheathed cable and flexible cord to steel outlet boxes or other metal enclosures. A reversible locknut cuts through protective coatings on boxes and enclosures to preserve grounding.
In reading NEC's Chapter 314.17 (C), it states that any nonmetallic sheathed cable entering a nonmetallic box must be clamped inside the enclosure. There is an Exception to this requirement, but it only applies if the enclosure dimensions are not . The clamps on the illustarted box are specifically for AC/MC cable. Note the wide openings and slightly slanted dent on the clamp. That is for engaging the armored spiral in MC. I don't like specialty boxes like this that are only designed to work with one style of cable.
