Electrical Code and Protecting NM Cable

Installing and Protecting NM Electrical Cable – The NM Cable must be positioned and fastened so that the cable will be protected from damage especially when the wall coverings are installed.

Providing Protection for Electrical NM Cable
Electrical Code Question: In a wood framed wall with studs positioned so the wall cavity is 1-1/2″ deep.
How is a vertical length of NM cable supported on the edge of the stud.
The CJ appears to protect only the length of the cable within the support.
Is the balance of the cable protected by its flexibility to move out of the way?

This electrical code question came from: Jim, a Educator from Florissant, Missouri

Dave’s Reply:
Thanks for your Electrical Code Question Jim.

Installing and Protecting NM Electrical Cable

• The NM Cable must be positioned and fastened so that the cable will be protected from damage especially when the wall coverings are installed.
• The NM Cable must be secured to protect it from sheet rock screws to avoid penetrating the NM cable.
• If the depth of the wall does not provide enough depth and safety space then installing the electrical wiring using metal conduit or armored cable may be necessary.
• Check with your local building inspector who has been assigned to your project for a determination.
