Are the rules the same for designing OCP for the primary and secondary of a 208V:208Y/120V isolation transformer as with a 480V:208Y/120V transformer. Basically, 250%-primary and 125% on the secondary.
Thank you
The basic 600Vmax 9Amin rule is: primary OCPD not to exceed 125% FLA unless a 125%max secondary OCPD is supplied in which case the primary OCPD can be upto 250%.
