Although there is no rule that relates to connectors, these are rated for only 60 amp. While the breaker is rated for 40 amps, it is designed to handle 600% over current for brief periods of time. The CIM motors stall at 131 amps. If you were using these for a CIM motor, I would expect them to fail in a stall condition. After doing some research, I could not find that these connectors are UL rated. Lacking the UL label makes them suspect for the 60 amp rating. The Anderson Power Products connector line is UL rated and tightly tested as an example.
