How does Electrical Fire happen?
A high current fault can create an electrical fire by forming a high energy arc flash which rapidly vaporizes metal and insulation material. An electrical explosion is the sudden release of energy due to a short circuit between power phases or a phase to ground. It is important to realize that a very large amount of energy is available on the bus of most electrical panels when they are operating within their normal design parameters. For example a phase to phase short circuit on a 400 Amp, 120/208 Volt panel can instantaneously release over 100 kilowatts of energy during a fault condition and not blow the protective fuse or circuit breaker. An electrical explosion of this magnitude will destroy the panel and can start a fire causing severe injuries.
In simple terms a short circuit is a low resistance path for an electric current to flow between two conductors supplying electrical power. Since the volume of current flow is huge this may cause the electrical power source to get damaged, sometimes permanently. If ever we have a fuse in the circuit it will act as a protection device and blow out thus opening the circuit and preventing any further damage.
