Topic tags/keywords: table saw planer hosepower hp 5 motor circuit electrical

I have a 5 horsepower motor on my 12 in Grizzly tablesaw and was wondering what gauge wire I should be using as well as what type/size of breaker I need. I am a little confused because the motor is rated at 30 amps (stamped on the motor), but in the equipment manual it says the saw should be fused at 30 amps. I’m sure someone on here can clear this up for me!

I also have a planer with a 5 horsepower motor. This motor is rated at 25 amps. Again, what size wire and breaker do I need? I will have dedicated circuits for each of these pieces. Thanks for the help!

The code says #8 wire, 60 amp breaker or 40 amp dual element time delay fuses on 240 volts.
