20 AMP power to motor controllers?

[Fletch1373]

I've been unable to find a rule this year that specifies what motors are allowed to be connected through what breakers, but historically CIMs have required 40A breakers. This is due to it having a much higher stall current(in the 60A range if memory serves).

If you do decide to put a CIM on a 20A breaker, just remember that the breaker is there to protect the wire, but there's still a chance of the high current burning out the wire before the breaker trips if the motor stalls. The AWG requirement in table 4-3 is just a minimum, so feel free to go higher in this case.
