Mell What is short circuit and why it is dangerous?
Short circuits are a major type of electrical accident that can cause serious damage to your electrical system. They occur when a low-resistance path not suited to carry electricity receives a high-volume electrical current.
Why is an electrical short circuit dangerous?
Short circuits are abnormal electric connections which allow additional electricity to run through your switches, appliances, and outlets. The additional heat generated by the extra electricity can also cause fires in the affected wires and reach the flammable parts of your home.
Why is a short circuit in a house so dangerous?
Because if they were not there, your circuit’s wire embedded in your home’s wall would heat up by conducting a current well in excess of its designed current and eventually start a fire inside your wall cavity. Hope your house doesn’t burn down, especially with people inside it! A short circuit occurs in your car’s electrical system.
When does a short circuit occur in an electrical circuit?
What Is an Electrical Short Circuit? A short circuit refers to a specific condition in which electricity strays outside the established pathway of an electrical circuit. A short circuit happens when electrical flow completes its circuit journey via a shorter distance than is present in the established wiring.
What does it mean when a circuit has a dead short?
A dead short is when an electrical circuit has zero resistance. This can result from the “hot” electric feed coming in contact with a metal object, like a metal outlet box or with the ground or neutral wire. Your initial sign that you may have a dead short will be a tripped breaker.
What to do if you suspect an electrical short circuit?
Follow this procedure if you suspect a short circuit: Locate the tripped circuit breaker: At the main service panel, look for an individual circuit breaker with a handle that has snapped to the OFF position. Some breakers may have a red or orange window indicator to make it easy to spot.
