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?

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.

The Safest Way to Test Electrical Devices and Identify Electric Wiring!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
