What is an MCB busbar used for?

It distributes the phase feed across a row of miniature circuit breakers, connecting each unit at a common terminal spacing.

How is it installed?

The busbar slots into or clamps onto the incoming terminals of each MCB, replacing individual loop cables.

How is the number of ways chosen?

The busbar's way count is matched to the number of breakers in the row, and excess ways are broken off when sized to fit.

Where is it used?

It is used in distribution boards and consumer units where several MCBs are fed from one supply.

Is the live busbar protected?

The busbar is covered or sleeved so that live parts are not exposed during normal wiring and service.
