I was cutting some 16/4 poplar on the tablesaw and got halfway through it
when the saw stopped dead.

At first I thought the blade had simply stopped but then I realized the
motor was completely off. Breaker on the tablesaw has popped. Once I reset
it and gave the motor some time to cool down it worked just fine.

I've never had anything like that happen to me so I'm wondering, what was
the principle cause. Obviously without being there no one can nail it down,
but in general would this be due to a dull blade and too fast a feed rate or
simply overuse/misuse of the saw? I'd probably run 20 feet of this stuff
through the saw prior. Let me be clear, I don't have a saw that can cut 4+
inches in one pass, so I was having to cut, then flip and finish the cut
(and maybe that's the big no-no here)
