The Dangers of Short Circuit

Muddassir Katchi March 27, 2018 0

Short Circuit: When Two Nodes of an Electric Circuit, intended to be at Different Voltages, Form an Abnormal Connection

The Resultant Electric Current Can Cause

  • Circuit Damage
  • Fires
  • Explosions
  • Overheating

A Short Circuit Fault is Thousands of Times More Powerful than Normal Operating Current

The Hazards

  • Short Circuits Can Cause Debilitating Injuries, and Even Fatalities, Among Electricity Workers
  • Energy Arcs from Short Circuits Cause Fires and Explosions – Which Result In Damaged Equipment

Workers Can Receive Shocks, Burns, and Injuries from Flying, Fragmented Metal

Arc Explosions are Particularly Violent in Atmospheres with Flammable Gases, Vapors, and / or Combustible Dusts

Workers are at Risk of Becoming a Short Circuit Themselves

It Can Happen If the Worker Accidentally Touches a Hot Wire with Wet Hands

In Extreme Cases, Short Circuits Can Burn Down Houses and Entire Buildings

The Prevention

Short Circuits Can Be Reduced or Prevented through:

  • Fuses
  • Circuit Breakers
  • Overload Protection

Essentially, the power must be disconnected in reaction to excessive current.
