i didnt mean to come off as an ass, but now that i read it, i kind of
do..

all i mean is that if you want to start doing the math, there are many
factors involved. the load conditions on startup. the load conditions
during running. and none of these are simple to calculate but most
motor
manufactures will provide charts.

but in any case, if you cant run your 5horse motor on a 30 amp circuit,
something is wrong.

Delta states a requirement of a 40 amp slow blow fuse for protection on
their 5 HP Unisaw. It may run on a 30 amp circuit, but I would not bet on
it!

well, i cant vouch for that particular motor, but imho a 40 amp slow blow
fuse on a 5hp table saw motor is kind of like saying, ok, once the thing
catches on fire and explodes and the blade has spun out of control and the
power wires are actually touching and welding together, we better stop
supplying current to it g

i would bet that saw has internal protection that blows long before that
fuse does.
