For temporary installations, Type NM and Type NMC cables shall be permitted to be used in any dwelling, building, or structure, up to a maximum height of ___ feet.

For temporary installations, Type NM and Type NMC cables shall be permitted to be used in any dwelling, building, or structure, up to a maximum height of ___ feet.

• A. There is no height limitation.
• B. 30
• C. 20
• D. 40

Answer: (A)

The limit that matters here is not a specific height for NM/NMC cables when used temporarily inside a dwelling, building, or structure. In temporary installations, the NEC does not impose a maximum height for routing these cables. The emphasis is on safe, temporary use—keeping the conductors in a dry location, protected from physical damage, and properly supported—while recognizing they’ll be converted to permanent wiring later. Because no height cap is specified for this temporary-use scenario, there is no maximum height. The other figures would imply a limit that the code does not establish for temporary NM/NMC installations.
