Note those are only rated for 45A when used with 10 ga wire in a single configuration. With a 12ga wire they drop to 35A in a single configuration. Connect them in a multiple configuration and with the 10ga wire the rating drops to just over 30A per terminal, with 12ga it is just over 20A per terminal for loads occurring for more than ~1 minute.

As I noted above you need to consider not only the size of wire it will accept, but the ampacity of the terminal and the ampacity of the connector as a system.
Of course that doesn't mean that you can't get away with it as we all do with the legal battery connector which is only rated at 60 amps when fitted with 6ga wire for the duration of a standard FRC match. Yet it is "protected" with a circuit breaker rated at twice that.
