Hi all I supervise Inmate apprentices and they do a lot of studying. They were doing the 2014 Electrical Exam Preparation and discovered a problem. On page 175 under Terminals rated 90 deg. C, It asks: According to table 310.15(B)(16), what size 200 amp aluminum compact conductor can be used to interconnect bus bars protected by a 200 amp overcurrent protection device if all terminals are rated 90 deg. C? It says the answer is 1/0 AWG. The code and table says that 4/0 is the size. Could someone explain it so I can explain it to my apprentices.:rant:
