While many people believe that short circuits refer to all wiring problems, most electricians would tell you that it's more complicated than that. When your appliances and lights don't turn on, the problem can be traced back to several electrical issues. To help clear up the confusion, here's what you need to know about electrical short circuits.

What Is a Short Circuit?

A short circuit occurs when electrical flow deviates from its original circuit and passes through a shorter route that offers little to no resistance. During a short, too much current suddenly flows through the circuit, which may trip the breakers and cut off your electrical supply. 

Short circuits happen when a hot wire either comes in contact with a neutral line or touches components like bare ground wires and grounded metal boxes or appliance parts. Contact a professional electrician whenever you notice loose wire connections or faulty wiring. 

Why Does an Electrical Short Circuit Happen?

The three leading causes of electrical shorts are faulty circuit wire insulation, loose connections, and incorrect appliance wirework. Old or damaged circuit wire insulation can no longer serve as effective barriers between hot and neutral wires. When these two wires touch, they can create an electrical short circuit. Similarly, live and neutral wires can come in contact when connections or attachments become loose. Lastly, faulty appliance wiring can trigger an electrical short, as these become extensions of your circuit once you plug them in. 

How Can You Prevent a Short Circuit?

One essential step is to schedule annual inspections by qualified electricians. These checks identify and resolve critical problems before they put your safety at risk. Additionally, install or maintain breakers and ground-fault or arc-fault circuit interrupters. These devices help prevent fires and electrocution by shutting off electrical power when they detect abnormal current flow.
