[QUOTE="ffkk, post: 2538112, member: 571765"] My input: In all power systems, equipment will have different ratings viz. steady state or continuous and a transient rating like during a fault or switching surge. So a fuse or breaker should be rated to break a current during steady state and fault conditions in the milliseconds range otherwise the protection and other equipment in the path of the fault that's rated below the fault current could get damaged. some types of loads require high fault levels, like furnaces/smelters. normally they require a short-circuit to load ratio (SCLR) >10. So for a load taking a continuous 1000 Amps will require no less than 10 000 Amps of fault level in order for their processes to work well and to minimise voltage dips in the power system. I believe this is analogous to an audio system that requires huge amounts of power for a few seconds, hence isolation in terms of protection is of great importance. Cheers [/QUOTE]
