I am looking for std's which might outline the requirement for circuit breakers for the DC supply source in this type of buss IE neither conductor is grounded, the source is feeding a battery bank and a distribution panel which provides branch crct protection. I am specifically trying to find out if there is a requirement for both conductors to have a breaker. If you are aware of any standards that might directly address this OR might do so by implication IE only state requirement for 50V or greater etc. etc. your information would be appreciated. Please reply to coates@ieee.org
