  1. Electricians ECCODES A Leader in Education Temperature Terminations

  2. Question: ECCODES What size conductor is required if the load is 20 amperes, and the terminations are not marked? A Leader in Education a. # 14 b. # 12 c. # 10 d. #8

  3. ECCODES If you have selected the wrong answer. Don’t give-up try again A Leader in Education Back to the question

  4. Article 110 You have answered the question correctly. ECCODES Assumed 60-Deg. Assumed 60-Deg. • Conductors are sized to the lowest temperature rating of the • Conductor • insulation • or • Equipment • Raceway • Enclosure 20 Amp Load Conductor OCPD A Leader in Education Answer: A#12 conductor, copper, in the 90 ͦ column of the ampacity table in 310.15(B)(16) equals 30-amperes but you can never exceed temperature termination, insulation of a conductor, equipment etc. . Therefore, with no markings we’re are limited to 60 ͦ markings thereby limiting these conductors to 20-ampere ampacities. But, what if… . Next

  5. Question: ECCODES But, What if conductor terminations and equipment etc, are rated 75 ͦ. Then, what size conductoris required if the load is 20 amperes, and everything is marked @75 ͦ? A Leader in Education a. # 14 b. # 12 c. # 10 d # 8.
