Hello,
Can I have an extra check on my wire and fuse size calculations please?
480V 3 phase, 50amp load, 1000 ft from power supply to load.
3% allowable voltage drop per code.
Results
AWG 1 for the 3 phases conductors and Ground sized to AWG 10 (Table 250.122)
Fuse size: 125% of 50 = 62.5 amp fuse. I choose 70. (210-20(a), and 215-3)
Thanks for the help. I hope I did well.
Thanks for your help in advance
