Putting too much pressure on a water hose can make it burst. The principle is similar for electric wires: if too great a current flow is required by several items of equipment connected to the same line, this produces overload.
Avoid therefore as far as possible:
- plugging several power-hungry items of equipment into the same socket using a multi-socket extension
- plugging several power-hungry items of equipment into different sockets connected to the same electric line
