Arc flash is different from the arc blast, which is the supersonic shockwave produced when the conductors and surrounding air are heated by the arc, becoming a rapidly expanding plasma.

When an arc fault occurs, the result is a massive electrical explosion. The light and heat emitted by the explosion is known as the arc flash, and the pressure wave is known as the arc blast.

The energy released in the arc rapidly heats and vaporizes the metal conducting the electricity, producing an explosive arc blast resulting in deafening noises, supersonic concussive forces, and …

May 1, 2024 · Arc flash describes the intense light and heat generated during electric arcing, while the term arc blast can be used separately to refer to the pressure wave created from an electric arc.

Mar 26, 2025 · An arc flash is a sudden electrical explosion or discharge that happens when electric current travels through the air from one conductor to another. It can also be defined as a dangerous …

Aug 20, 2024 · This phenomenon occurs when an electric arc causes a sudden release of electrical energy due to a fault, which can cause a bright flash and intense heat, leading to fires, explosions, …

Why do arc flashes happen? Learn how electrical faults, equipment failure, and human error trigger arc flash events and how to reduce risk with proper training.

Arc flash videos, examples and more. Arc flash is a complex phenomenon that is an electrical explosion resulting from a low-impedance connection to a voltage phase in an electrical system.

Feb 3, 2025 · An arc flash occurs when an electrical current jumps across an air gap between conductors, generating an explosion of intense heat, light, and pressure. This can happen due to …
