British plugs, also known as BS (British standard) plugs, specifically refer to power plugs that use British standards as a reference standard. There are two types of British plugs: modular and injection molded. Modular British plugs are detachable and can be customized freely, while injection molded plugs are generally integrated and cannot be disassembled. Common British standards in the market include BS1363, BS546, BS5733, etc., which stipulate the standards that a product must follow when entering the UK. The British plug has three square pin connectors, with three poles of "E, L, and N". The E (Earth) pole is the ground wire, the L (Live) level is the live wire, and the N (null) pole is the zero wire. It follows the principle of "left zero, right fire, and middle", and is generally marked on the plug. The corresponding current and voltage values are also marked on the British plug, and the English plug with a fuse will be marked with the word "FUSED". The spacing between the three copper pins of the British plug is the same, and the L-pole and N-pole pins are covered with glue for safety protection
