Arc Flash

What is Arc Flash?

Arc flash results from an arcing fault, where the electric arcs and resulting radiation and shrapnel cause severe skin burns, hearing damage, and eye injuries. Arc flash temperatures can reach or exceed 35,000 F at the arc terminals.

Why should I perform an Arc-Flash Analysis?

Without an Arc-Flash Analysis, you cannot protect your employees from an arc-flash. It is imperative to know realistic values for fault current as well as clearing time for protective devices in order to determine the proper Personal Protective Equipment (PPE) for your electrical workers.

Guessing or assuming an infinite bus can be dangerous! Only a complete system analysis allows for proper hazard assessment and recommendations for the appropriate Arc-Flash Protection.

Regulations Regarding Arc Flash Protection:

OSHA and the National Electric Code (NEC), NFPA 70E: Standard for Electrical Safety Requirements for Employee Workplaces, require proper warnings for qualified workers, to warn of arc flash potential and provide information for proper protective equipment for personnel.

Federal regulations require that switchboards, panel boards, industrial control panels, and motor control centers in non-dwelling occupancies, that are likely to require examination or service while energized, be marked and/or labeled to warn qualified persons of the arc flash hazard.
