The distribution board or distribution board is an important component of the power supply system. Its function is to transmit the input power to multiple secondary or auxiliary circuits.

In most cases, these secondary circuits are protected by fuses or circuit breakers. In the UK, distribution boards like PM861AK01 are commonly referred to as consumer units in household properties.

The terms user unit and distribution board cannot be completely interchanged. However, in most practical applications, their meanings are the same. A distribution board may also be referred to as a distribution board, circuit breaker panel, or simply a distribution board.

The distribution board or circuit breaker panel divides the input main power into different sub circuits. Usually, all fuses, circuit breakers, and other circuit protection devices for these secondary circuits will be placed in the same enclosure. However, not all distribution boards must be enclosed; Some are only semi enclosed, while others remain open.

Most workplaces rely on distribution boards to distribute and route a single external power source to multiple smaller circuits around the building. In many such environments, PM861AK01 circuit boards are enclosed for safety reasons. This housing is commonly referred to as a fuse box.
