Hi! I am trying to find out if there is a Canadian equivalent to the NEC tap rules of NEC 240.21(C). Specifically, do conductors feeding a panel from a transformer (480V-208V, delta-wye, 3 phase) need to have overcurrent protection at their supply (the secondary of the transformer). The NEC does not permit the primary overcurrent device to protect the secondary conductors in this case. There are also qualifications in the NEC for conductors less than 3m long, etc. Does the Canadian code have a similar requirement?

Thanks for any help you can give me!!
