Electrical advice needed

The poor guy is asking for help (see my first post) not quotes from a code book.
I'm not replying any further, I've seen too many others argue with you, and no good ever comes from it.

Don't be posting guesses when you don't really know. Wrong on several accounts .

I'll list this as a "snark"...thanks for your post...

Every board on the internet has them. I just learn to ignore them.

Read the manual for the machine - Section 2 - http://cdn0.grizzly.com/manuals/g8622_m.pdf

Dedicated 30 amp breaker - We recommend using a NEMA-style L6-30 plug and outlet (which is a 3 wire cord)

If it is 220 volt, you do not need a neutral, but you do need a ground !

Opps read the specs. on the equipment.. It says it want a 4 wire power cord.....

A motor with 30amps full load operating current is supposed to be supplied with breakers or fuses larger than 30 amp. To prevent tripped fuses or blown fuses during starting inrush current .
The 70 amp breaker is there for short circuit protection with many of you are confusing with thermal protection. Thermal protection is provided by the heaters located in the 30amp motors starter/contractor box. Thermals by the way are to be set at 115% of FLA if the motor's service factor is 115% . 34.5amp on the thermals. The thermals in the machine are what keeps the building wiring from melting, not the supply breaker .
Why are you getting angry and shooting the messenger ? Who are we going to trust on electrical specs? The engineers that wrote the code book? Or are we going to believe Bubba the self taught electrician ?
Anybody here ever seen a cell phone charger plugged into a 20amp T-slot receptacle ? Where is the protection there ? Nobody gets worried .

Full circle.

Only you did better with the details.

Same point I made. Breaker is to protect the circuit, not the device. (I used a box fan on 20a circuit analogy).

You could plug the motor into a 200a circuit. It dont care as long as it at least meets the minimum requirement of the motor.

Still would like to know what this piece of equipment is? 30 FLA motor is pretty big for a piece of wood working equipment. I dont think we ever got clarification if that was accurate or not? And I dont think a 70a breaker is all that common for a typical panel that would be found in a home or residential shop

I apologize for not responding promptly to all the well intentioned responses. I've been busy with quite a few things. It seems everyone has been curious about the machine in question. It is a planer molder and this is directly from the manual; Motor is 230 volt, 30 amps. Recommended receptacle is 6-30R.

My brother's son in law is a commercial electrician with around 20 years experience. He has agreed to help with the wiring, and I feel comfortable with his competence. Although I haven't talked to him yet, I will defer to his recommendations.

Again thank you for all the good responses. As always TBN is a treasure trove of knowledge.

If FLA really is 30.0 Amp. The 6-30R is too small. The classic 6-50 welding receptacle and plug would be code compliant. Of course the 6-50R would work with just about an modern welder.
