What does a British socket look like?

The British socket is a socket with three square pins.

The British plug has three square pins, with three poles "E, L, and N". E (Earth) is the ground wire, L (Live) is the live wire, and N (Null) is the zero pole. The wires follow the "left zero, right, fire, ground, middle". Generally speaking, there will be a mark on the plug.

British plugs are also marked with corresponding current and voltage values, and British plugs with fuses are marked with the word "FUSED". The three copper pins of the British plug have the same spacing between the top, bottom, left and right, and its L and N poles are covered with rubber for safety protection.

Extended information:

British plugs can be used as supporting electrical appliances and can be used in industries, homes, businesses and other places. In particular, when British plugs are exported to the UK, they need to have BS certification. If they are exported to other countries such as India, the certification requirements are not strict.

In addition, some countries have local protectionism. When exporting British plugs, they need certification from their own countries. For example, Saudi Arabia also uses British plugs, but when we export plugs to Saudi Arabia, we also need Saudi Arabian certification. Certification SASO.
