Extension cords seem like a safe place to save a few pounds by buying something cheaper.
It's a bad idea and could very easily lead to a serious fire.
The other day a friend handed me an extension cable that they'd found in their home office and asked me for my thoughts on what had happened. According to the owner, the extension cord had not been overloaded.
Here's the extension lead one of the terminals had melted to the point of being unusable and completely unsafe.
My diagnosis was a simple one -- poor quality product. And on taking it apart I spotted several issues that point to terrible quality control.
First, the reason for the overheating is poor quality contacts. The one that melted is the most obvious, but many of the others are showing signs of overheating.
