A CEE plug (also known as an industrial or power plug) is often used in situations where higher power or special electrical applications are required. Here are a few reasons why a CEE plug is used:

1. Higher power: CEE plugs are designed to handle higher currents and powers than standard household sockets. They are often used in industrial environments, construction sites, campsites, marinas, and other locations where heavier equipment, machinery, or vehicles need to be connected.

2. Safety: CEE plugs are designed with special safety measures to ensure security. They usually have robust construction, sturdy housing, and locking mechanisms to ensure that the plug remains securely in place and is not accidentally disconnected.

3. Water and dust resistance: Some CEE plugs have an IP44 or IP67 rating, meaning they are water and dust resistant. This makes them suitable for outdoor use, in humid environments, or in situations where protection from water or dust is required.

4. International compatibility: CEE plugs are used worldwide, and there are different types of CEE plugs with standardized designs and pin configurations. This facilitates international compatibility and allows equipment to be easily connected in various locations.

The use of a CEE plug depends on the specific application and the requirements of the electrical equipment. It is important to select the right CEE plug based on the power, voltage, and configuration needed for the respective application. It is also important to follow safety regulations and electrical standards when using CEE plugs.
