WHAT IS AN ARC FLASH?

An arc flash is a current flowing through air that flashes from one exposed live conductor to another conductor or to ground. When an arc flash happens, the temperatures can reach up to 35,000 degrees Fahrenheit. This is four times the temperature on the surface of the sun. The result can be destruction of equipment, fire, and injury.

WHAT CAUSES AN ARC FLASH?

An arc flash occurs when electrical clearances are reduced or compromised by deteriorating insulation or human error. The arc flash follows a conductive path between two hot (energized) wires or between a hot wire and ground.

WHY IS AN ARC FLASH ANALYSIS IMPORTANT?

Without an arc flash study you will not know the actual level of danger or the appropriate personal protective equipment (PPE) required for employees. Electrical systems are dynamic and change over time. Internal changes, such as adding new equipment can affect the level of arc flash energy. A study must be updated every time the system changes. External changes, such as a utility changing transformers or changes at your utilityʼs closest sub-station can severely impact your level of arc flash energy.
