Rick....my wheels fell off as soon as I left my shop..
And herein lies the root problem....no one read the question, including you. The original poster wasn't asking a code question. He was asking how many conductors the circuit would require. So you have nearly 80 postings giving advice for questions not asked. People are so busy running around shouting, "hey look at me, I know something" that they jump to their keyboard before they've even had the chance to digest what the person is asking about.
So going way back to the first few postings that already answered this, he needs to use 2 current carrying conductors plus a ground. And given the way his followup question was asked, no, he cannot reuse the 50 amp breaker. That's it.
80 posts of the wheels falling off the bus.
He didn't ask what methodology to use for the wiring. He asked the simple question of how many conductors were needed. YOU interjected all of the nonsensical garbage that you felt he was too incompetent to know without your tutelage.Nope, you're not alone here. There are nearly 80 other postings that are doing exactly the same thing. That's the problem.Rick this wasn't to argue just to state I did read enough to know it's not simple answer but could be a little more complex not knowing their code/s.
Did it not occur to you that when I originally mentioned the wheels coming off the bus/wagon, that I was actually referring to you personally? Your post was directly above it, and it was my quasi-polite way of telling you that you should not be answering electrical questions. Sorry, but I'm not feeling so "quasi-polite" tonight.Sorry Rick.
It is Two current carrying wires AND a neutral wire AND a ground wire.
Aside from code (NEMA and Local rules) and best practices many table saws these days have a magnetic power switch. All the ones that I have seen need 115 volts to operate the magnetic power switch. Without neutral, the saw probably not turn on.
