The utility company we are working with will not work on a customers primary line if it is fused over 200amp Primary because they do not stock fuses large enough to service the equipment. We have a customer that has a need of 400 amps Primary capacity. Assuming all wire sizing is ample, what are the disadvantages of installing (2) sets of 200amp fuses in parallel per phase?
