That should be ok. A basic principle of electrical system design is that the circuit protection is intended to protect the wiring, and supplied equipment has its own protection, and does not rely on the power supply system for protection. As long as the wire to the charger is adequately protected by the circuit breaker you are following industry practice.jdavis said:... The charger/converter would be on one of those 15 amp breaker protected circuits. 15 amp breaker doesn't seem ideal to me, since the converter should only be using about 5 to 6 amps, but I could not find a smaller breaker.
That's a great point. Thanks!Jon R said:That should be ok.

From a brief conversation with Marty @ATC, I was under the impression that an external CB was required. If the CB in the converter meets standards, all is well.Jon R said:Wandering Sagebrush,
While what you are suggesting wouldn’t hurt, I think that what he has in his drawing would be considered acceptable. The idea of the related codes is that the connector type is only to be installed on a 30 amp cord, which is only to have a 30 amp specific connector on the other end so it can only be connected to a 30 amp circuit receptacle. By sizing the wire in the camper from the external connector to the first circuit breaker panel for 30 amps, that wire is adequately protected by the circuit breaker that protects the shore power circuit.
Thanks, that's a great suggestion.ntsqd said:I would consider moving the 30A breaker between the buss bar and the fuse block to be between the battery and the buss bar. I'm in the camp of having some sort of protection as close to the battery as possible, putting the fuse or breaker between the battery and everything else. Depending on the number of your connections the out terminal of the break can be your buss bar.
