Question

a conduit found in a boiler room with an ambient temperature of 75 degree celsius. the ampacity of each conductor is?


14.8A
17.0A
48.0A

Answer 1

My table only lists a max. of 3 conductors, so obviously the standard has been updated since then. For 3 conductors the answer is 18.5 Amps, so the correct answer must be either 14.8 or 17.0A.
