My response was that a motor needs to have overload protection usually 125% in addition to ground fault and short circuit protection. If a motor does not have that protection built in and there is no fuse or circuit breaker that meets the need at 125% you end up with a starter or contactor either manual or electrically operated that can contain the proper size overloads. This can also be an issue with small motors such as I've seen on roof-top exhaust fans where usually they field install a small toggle type switch that can accommodate an overload element.
