What is the standard height of the socket from the ground?

the standard height of the socket from the ground is generally 3-5 cm, and the specific height should be determined according to the use place and ergonomic principles. For example, the height of household electrical outlets is generally 3-4 cm from the ground, while that of public places such as hotels and offices is generally 4-5 cm. At the same time, the installation position of the socket should be convenient to use and not easily blocked or affected. When installing the socket, we should also pay attention to the safety and waterproof of the socket to ensure the safety of use.
