The way I read it:
If series rated circuit breakers are used, the circuit breakers must be listed for the use. Obviously I am not going to fined a main circuit breaker that will be listed for 50 year old branch circuit breakers.
On the other hand, current limiting devices can be used to protect the down stream circuit breakers.
Agree or disagree?
If the above is true, the next question is - can current limiting fuses be installed in the service entrance before the main disconnect (see 230.82(1)) and can they be used to calc. the available short circuit current at the circuit breakers in the main switch gear?
