On paper yes, but since continuous 13A appliances are rare in modern houses you don’t find out where someone’s cheaped out or failed to tighten screws until you plug in an EV charger. Lots of places it can go wrong:
- Bad joints or cheap metal it the socket.
- Dirt or corrosion on the pins
- Bad joints to the plug pins
- Skinny wire in the extension lead
- The fuse kicking out more heat than the surrounding plastic can take.
The last one seems to be the most common.
- Bad joints or cheap metal it the socket.

What specifically melts on extension leads then? Is it the plug overheating due to a poor connection between the pins and the socket, or is it because people leave the extension lead coiled up and it cooks itself? I thought our UK plugs were designed to take a continuous 13A, not max/peak for short periods.
