Arc Flash

What is an Arc Flash?

An Arc flash is a type of electrical discharge as a result of a low-impedance connection through the air between two conductors

An Arc Flash is typically caused by accidental contact, dropping tools, insulation failure, condensation or dripping water, dust, and corrosion of equipment parts

An Arc Flash can release large amounts of energy and produce intense heat, reaching up to 20,000° Celsius. This is four times the surface temperature of the sun.

Why is Arc Flash analysis essential?

An Arc Flash study is an engineering investigation for identifying the specific Arc Flash hazard of any given piece of equipment.

Several regulations, codes and standards define requirements for Arc Flash safety, including OSHA, NFPA 70E, CSA Z462, and NESC.

Article 130.5 of NFPA 70E requires employers to perform an Arc Flash risk assessment for electrical equipment to identify all Arc Flash hazards present and to update the study at intervals not to exceed five years.

A regular update of the Arc Flash study will ensure compliance with codes and regulations as well as safeguarding personnel and the electrical installations.
