can anybody tell me why "Arc Fault Circuit Interruptors" are used and they are mandatory specially for bed room receptacles as per certain electrical codes. Also please let me know how we selectively coordinate them with other protective devices.






RE: can anybody tell me why "Arc Fau
As far as coordination, these breakers are usually going to be the last breaker in a circuit. Since they will be much more sensitive than the regular upstream breakers, there should be no coordination problem. If one of these devices is used upstream of a regular breaker, coordination is most likely not possible.
