The British plug is a three square pin plug with "E, L, N" three poles. The E (Earth) pole is the ground wire, the L (Live) pole is the live wire, and the N (Null) pole is the zero wire. It follows the principle of "left zero and right fire in the middle". Generally speaking, the plug will be marked. The British plug is also marked with the corresponding current and voltage values, and the British plug with fuse will be marked with "FUSED". The spacing between the three copper pins of the British plug is the same. Its L and N pole pins are coated with glue for safety protection.

British plugs can be used as supporting appliances in industrial, family residential, commercial and other places. In particular, when British plugs are exported to the UK, they need to have BS certification. If they are exported to India and other countries and regions, the certification requirements are not strict. In addition, some countries have local protectionism, and British plugs need to be certified by their own countries when exporting. For example, Saudi Arabia also uses British plugs, but when we export plugs to Saudi Arabia, we also need Saudi SASO certification.
