Hi All,
I have a 2MVA 4160 to 415V delta wye Transformer. I would like to connect from the transformer secondary bushings to four 800A Panel boards each with a main 800A breaker. In this instance there is no protection on these cables at the point of connection to the transformer. Each 800A Panel board would be fed with 4 runs of 3/0 copper 4C cable.
In what scenario does this configuration pass code in Canada?

Thanks in advance.
