Good morning, Jim. The Code reference you cite is it, as far as interrupting capacity goes. The NFPA isn't going to stick it's neck out any further and the shouldn't. The rationale is that each application could be different, some having 10 kA, some having or 100 kA or greater fault current

One (easy) way is to enter the ABS rules at http://www.eagle.org/rules/downloads.html The hard part is to analyze the rules and find all the specific requirements for EMC, climate, mechanical, performance, etc ... In addition, you will need to produce test plan which should be approved by ABS
