In which locations is type NM cable not allowed to be run?

How many Romex wires can you put under a staple?
Most metal and plastic staples or ‘wire holders’ can hold stacks of up to six to eight (6 to 8) Romex wires under them. You can stack even more if you can fit them or use thinner wires. However, it is not permitted by code to stack more than one 3-conductor cable under a staple, be it metal or plastic.
How far apart do you staple electrical wire?
One of the requirements for permanent wiring, and thus for temporary wiring, was the need for adequate support. Article 336-18 stated that cable must be secured in place at intervals not exceeding 4.5 feet (1.37 m) and within 12 inches (305 mm) from every cabinet, box, or fitting.
How do you install Romex staples?

One of the key principles in electrical code is to never have energized ends of wires outside of a box. The staples/anchors prevent the wire from being tugged on in the future and pulling out of the box. Staples + box anchor is a double-insurance that you might as well do when the walls are open.
How tight should Romex staples be?
Do not hammer in those cable staples too tight. They should be just enough to hold the cable in place, but not so tight as to pinch the cable. It may not look like the staple is damaging the conductors, and the problem may not present itself for a few years after installation, as was the case here.

What happens if you staple through a wire?
You shouldn’t be stapling wires down with regular staples like that. You’ll have reduced the cross-section of the conductor. That will reduce the conductivity and safety of the wire. You should cut out that part and reconnect the working wires again.
What is an NM cable?
The non-metallic (NM) designation refers to the outer sheathing that bundles individual wires together like a cable. This is in contrast to metallic sheathed cable or conduit wiring, in which the bundle of individual conductors is protected by some form of a metal coil or metal conduit.
