Question: 3 phase heater 480v. 45KW. What should the fuse protection be rated at? This is what I believe. 45000/480=93.75 93.75/1.73=54.19 amps.
Next greastest nominal size is 60amps. Is this correct? Also is there deratings or "pro" rating.
Anyone have any input, and exact fuse numbers that will work well. Just making sure these are indeed the right fuses.
Thanks
