Why is my Outlet Sparking When I Plug in Appliance

As a homeowner, I know you sometimes witness an outlet spark when you plug in an appliance. While it is common and mostly harmless, it can be an early sign of electrical problems.

This article will pinpoint the major causes of outlet sparking, and how to fix it. Read on for complete details.

What is an outlet spark?

An outlet spark is an electrical issue that arises due to a brief burst of electricity between an outlet and a plug. It can be caused by several factors, such as short circuit, moisture and circuit overload.

While some sparking can be normal, a prolonged spark can be a sign of a serious problem. It is thus important to know the differences so that you can take preventative measures on time.

Is it normal for an electrical outlet to spark?

Yes, a very small spark is normal when you are trying to plug an appliance into an electrical outlet. However, if you notice a large spark from the socket, there may likely be an electrical fault that needs to be fixed.

Why does my outlet spark when I plug something in?

Your outlet sparks for several reasons such as

Electrical short circuit

A short circuit can occur in an electrical system when a hot wire comes in contact with the neutral or ground wire. This can cause the outlet to draws more current, producing higher heat which may melt the wire insulators and cause electrical fires.

Circuit Overload

Every circuit breaker in an electrical system is rated to carry a certain amount of load. The higher the number of devices you plug into a single outlet, the greater the chance of sparking.

It is advisable to spread your appliances wisely across outlets and circuits.

Moisture or wet environment 

Water is a good conductor of electricity. If there is moisture around your outlet, it can cause it to spark.

Moisture can come from a leak within the wall or a splash if the outlet is in the bathroom or kitchen.

It is advisable to install a ground fault circuit interrupter (gfci outlet) in your bathroom or kitchen to protect you from ground fault.

Old outlet

With repeated use over time, an electrical outlet can wear and tear. When this happens, the chances of sparking and catching fire will be higher.

 It is advisable to have your outlets inspected by a licensed electrician and repaired or replaced if necessary, to prevent fire hazard.

Loose Connections

Over time, the wire connections inside your outlet or within the plug can loosen. This can cause arcing when two charges come into contact.

Substandard repair

If you hire a quack to install or or wire your electrical system, he may end up getting it wrong.  Always contact a professional electrician when you notice an electrical fault. 

Safety risks associated with sparking outlet

Sparking outlets can pose severe risks if ignored. Here are some risks:
