What are the specifications of power sockets in Britain?

British plugs are three square pins with "E, L and N" poles respectively. E (ground) is the ground wire, L (live) is the fire line, and N (zero) is the zero line, following the "left zero and right fire center". Generally speaking, there will be a sign on the plug. English plugs are also marked with corresponding current and voltage values, and English plugs with fuses will be marked with the word "fused". The distance between the three copper pins of the British plug is the same, and the L-pole and N-pole pins are encapsulated, which plays a role in safety protection.

British standard plugs are three-phase plugs, which can be bought in hardware and electrical stores.

The standard voltage in Britain is 240 volts and 50 hertz alternating current, just like other EU countries.

Electrical appliances between 230 and 240 volts can be used normally. Most 220-volt appliances can also be used, so it's best to check with the manufacturer.
