Electrical

One of our customers is upgrading their electrical system by replacing a 2.5MVA transformer to 5 MVA transformer ( 27.6kV primary). I am wondering if there is a CEC requirement to install a breaker on the primary side of the new transformer instead of a disconnect switch?
Thanks for all feedbacks
