I have read the Consumer Unit project and a thought occurs to me.
In the old type fuse box the live output of the mains on/off switch is fed to a bus bar within the fuse box which feeds each fuse.
In the consumer unit, there appears no busbar for the live feeds to the MCB's.
How is the live distributed?
Is there a special busbar for the live feeds to the MCB's
Many thanks for any info.
