Short circuit means there is a low resistance connection between two conductors that are supplying electrical power to a circuit. This would generate high flow current and generate excessive amounts of heat, and will result in melting wire.
1. Normal Short Circuit
2. Ground fault short Circuit
Normal Short Circuit means hot wire carrying current touches the neutral wire, the resistance will go down and a high amount of current will pass through it.
Ground Fault Short Circuit means hot wire carrying current touches with the grounded wire or grounded portion of the device. It can be a grounded metal box, or ground wire or a grounded portion of the appliances.
There are a number of factors that can lead to a short circuit. Here are some of the most common causes.
• Wiring encounters water or some other liquid
• Faulty insulation or loose connections can result in the live and neutral wires coming in contact with each other.
• Nail and screw punctures can cause damage to the wire casings.
• Pets like rats, mice and squirrels chew the wires which leads to the short circuit
• Old or malfunctioning appliances with damaged plugs or power cords can also cause a short circuit problem.
Short circuits pose a danger of shock and fire. We can take certain step to preventing a short circuit:
1. Use Circuit Breaker or Fuse: As the name states the circuit breaker work is to break the circuit. Depending on the rating of the circuit breaker it will break the circuit when the predefined amount of current passes through it.
2. Ground fault circuit interrupters (GFCIs) provide similar function to circuit breakers. They have an exact amount of setting of current and are more accurate than circuit breakers. It automatically shuts off the current’s flow at the slightest sense of fluctuation.
3. Arc-fault circuit interrupters (AFCIs) is a circuit breaker that breaks the circuit when it detects an electric arc in the circuit it protects to prevent electrical fires. These devices anticipate short circuits and shut the power off before it can reach a short circuit condition. Where GFCIs protect against shock, AFCIs are a better solution for preventing fires caused by arcing.
