True or False: The maximum amount of current a conductor can carry under the conditions of use without exceeding its temperature rating is found using calculation methods based in Article 310.

True or False: The maximum amount of current a conductor can carry under the conditions of use without exceeding its temperature rating is found using calculation methods based in Article 310.

• A. True
• B. False
• C. Not specified
• D. Not applicable

Answer: (A)

Ampacity is the maximum continuous current a conductor can carry without its insulation overheating beyond its rated temperature. The NEC defines this value and provides the procedures in Article 310 to determine it, using base ampacities in the tables and applying adjustment and correction factors for installation conditions and ambient temperature. By applying these Article 310 methods, you size conductors to handle the actual use without exceeding their temperature rating, so the statement is true.
