ECN Forum Forums Code Related Discussion Canadian Electrical Code Topics Why there is no requirements for CT or PT in CEC?

Tony,I have two questions to ask you after reading your post!
1)What is the relationship between C22.1 and C22.2? For a long time,I was confused that why I just have Part I of Code.Can u explain it to me?

2)I think that the proper clause that should be applied in this circumstance(I have a PT of 120VA) is C22.1-02,16-210(4).Do you think I am right?

Thanks!waitting for your reply!
