Awright Greg, let's see if an extreme example will clear this up for you.
Let's say you could find a 1000 amp breaker and installed it on the circuit
in question. Now let's say that something goes horribly wrong with the
motor and it starts drawing 200 amps ("cause it found a wrong ground or
something) The wiring starts to catch fire along with the surrounding
structure, but the 1000 amp breaker (or even the unrecommended 30 amp
breaker) thinks everything is just dandy, so it keeps that (or some other
excessive) current supplied to the fault in progress. Now if you had minded
the warning that 20 amp protection would be correct and proper, it would
have tripped and the fire department wouldn't be on the way.

Hope this helps

We
recommend using a 20 amp circuit breaker. Circuit breakers rated higher
will
not adequately protect the motor.

They don't provide overload protection? How did this product get a U/L
listing?
