What is a main switch consumer unit?

A main switch consumer unit is a type of distribution board that uses a single main switch to control the electrical supply to all outgoing circuits. It allows for full isolation of power and is typically used in setups where each circuit is protected individually by RCBOs.

When should I choose a main switch consumer unit over an RCD split load board?

Main switch units are ideal when you want to use RCBOs for individual circuit protection, offering better fault isolation and minimising the risk of nuisance tripping. They’re commonly chosen for properties with sensitive or critical loads, such as alarms, freezers or electric showers.
