How do you protect against arcing faults?
Unfortunately, it is impossible at this time to devise an electrical system that is completely "flash-proof", although significant efforts have been made.
However, personnel working on a system can take precautions to help protect themselves from the hazards associated with an arcing fault.
The National Fire Protection Agency (NFPA) requires that before a worker approaches exposed electrical conductors or circuit parts that have not been placed in an electrically safe work condition, a flash analysis must be performed. This analysis is to determine the flash protection boundary and the level of personal protective equipment that the worker must wear.
