What is 'incident energy' in the context of electrical safety?

Incident energy refers to the thermal energy measured at a specific distance from the source of an electrical arc. In the context of electrical safety, particularly when dealing with arc flash hazards, understanding incident energy is crucial. It helps in assessing the potential severity of an arc flash incident, guiding protective measures and personal protective equipment (PPE) requirements.

By measuring this energy, safety protocols can be developed to minimize risks to personnel working near energized equipment. Understanding incident energy allows for informed decisions regarding the safety measures needed to protect workers, as it indicates how much heat a person might be exposed to during an electrical fault. This understanding is fundamental in preventing injuries and fatalities in electrical environments.
