Oversize Primary Fuse on Transformer
Oversize Primary Fuse on Transformer
(OP)
The CEC code allows the use of overcurrent protection device rated at 125% of the rating of a dry type transformer with primary voltage below 750V, overcurrent protection on the secondary side is not required.
Are the transformers built to withstand the load at 125% for long periods of time? Is the 125% primary o/c rating to allow for in-rush?

Rule 8-104 (5),(a)
Most continuous loads are required to be supplied with conductors and overcurrent devices rated or set at 125% of the load current as a code requirement.
