The U.K. electrical system differs from the European way of doing things in more ways than just having a fused plug.

In the U.K. power and lighting circuits are separate. In each one the live wire goes out of the distribution box, wends its way around the house back to the distribution box creating a ring circuit. Likewise the return wire. Typically in a smaller U.K. house there will be about six circuits to supply the house.

In France the live wire leaves the distribution box but does not return. Lighting and power come off the same circuit. Typically a modern small French house would have more circuits.

The ring main methods allows the safe use of smaller diameter cable.

erre szokták itt mondani, hogy bár 16 de csak a felét lehet rákötni???
