[QUOTE="rich1, post: 555252, member: 35020"] This is another test question. Mulitple choice. Which circuit breaker operates fastest with a 300A fault current. 1. 32A Type B 2. 32A Type C 3. 32A type D 4. 32A Type C RCBO. I am thinking, as it's not been in any of the handouts, that a type B would see 300A as a short circuit and operate megnetically instantly (or in mS) where as a type D would take a few seconds for the thermal trip to operate?
