Should Extension Leads Spark?

Normal and Abnormal Sparks
If the electrical current is turned on for the outlet you are using, there will always be a spark that occurs when plugging in a device, such as an appliance or extension cord. A normal spark is blue in color. These sparks always occur, although may not witness them all the time.

Why does my extension lead spark?

This is normal for nearly any electrical device to need this initial surge at power on time. When you plug in your extension cord, this initial surge will begin at the slightest contact between the plug and socket. This surge will be through a very small contact point and can cause a harmless spark and crackle sound.

Can extension leads set on fire?

Extension cords can overheat and cause fires when used improperly. Overheating is usually caused by overloading or connecting appliances that consume more watts than the cord can handle. Damaged extension cords can also cause fires. Extension cords should only be used temporarily.
