To be absolutely safe, I would recommend a 4/0 AAC. Never mind that it's
larger than the 15kV distribution conductors.

A 3 hp single phase 220 volt saw motor will draw about 17 amps full load,
which is already more than 14 ga wire is rated for, but the starting
current
of that motor can be 150% or more of the full load current, so a 14 ga
wire
is WAY TOO SMALL. You should be looking for wire that will carry more
than
25 amps. A 10 ga wire is the right choice for a relatively short cable,
but
you should go to an 8 ga wire if the full length of the wire from the
breaker panel to the saw will be longer than about 100 feet.

Want to replace current 10' cord with 25' cord.
Is 14-3 large enough?

Saw is 3 HP 220V. TIA, F
