is there any code which requires fuses at commercial disconnects. I'm about to rebuild a disconnect for a restaurant and want to use a disconnect with a circuit breaker. I can't find a code addressing this issue
No NEC code requiring such - is this a local or local POCO thing to use fuses? If anything - that is if you are talking about main disconnecting means? - there may be AIC issues - in which case, series rating of the breakers used may become at issue...
