There are six current-carrying conductors in a raceway that is to be installed in an area with an ambient temperature of 90 ° F. It is necessary to _____.

A) apply a correction for the ambient temperature only
B) derate because of the number of conductors in the raceway only
C) correct for temperature and derate (because of the number of conductors)
D) no corrections or derates are required

Derate

To reduce the rated capability of electronic components or electrical devices due to environmental conditions or other factors.

Ambient Temperature

The temperature of the surrounding environment where a device operates or a process occurs.

Raceway

An enclosed conduit that forms a physical pathway for electrical wiring to be protected and routed through a building or structure.

  • Utilize correction factors for ampacity adjustments considering the quantity of conductors within a raceway and the surrounding temperature conditions.

Final Answer :
C
Explanation :
When there are more than three current-carrying conductors in a raceway, derating is required due to the potential for increased heat. Additionally, if the ambient temperature exceeds 30°C (86°F), a correction factor for temperature must also be applied. Therefore, both temperature correction and derating for the number of conductors are necessary.
