Trick440 ,, there some figures that dont really ring the bell to me but one question will the largest motors will start the same time or not ??

for me this what i will do is figure each motor seperately

25 hp @ 208v = 74.6 amp [ i did not add 125% yet ]

74.6 +74.6 + 46.2 + 16.7 = 212.1 amps

now i will add extra 25% on largest motor which is 18.65 amp more so the total load is 230.75 amp then go with 175% for **time delay fuse ** which it will say 402 amps but i can down size a little to even 400 amp but if you used the * non time delay fuse* the fuse size will jump up to 690 amp non delay fuse. the nondelayed fuse is sized at least 250% so that what it get ya on the figures

if more question just post it here

Merci , Marc
