In temporary wiring, NM and NMC cables may be used in dwellings with no height limitation. True or False?

• A. No height limitation
• B. There is a height limit of 30 ft
• C. Height limit 20 ft
• D. Height limit 40 ft

Answer: (A)

Temporary wiring is intended for short-term power during construction or repairs, so NM and NMC cables can be used in dwellings without a height limitation under those conditions. The emphasis is on safe, temporary installation and eventual removal, rather than on a fixed elevation. As long as the installation protects the conductors from physical damage, is properly supported and terminated, and complies with other temporary-wiring safety rules (such as GFCI requirements where needed and avoiding wet locations), it’s acceptable. For permanent wiring, different rules would apply.
