Hi all,

I noticed on my consumer unit that the main switch is rated for 100Amps, however the total load of all the MCBs is over 150Amps!

I appreciate that diversity COULD (?) be applied in that not every circuit would be simultaneously running at full capacity, but is the installation acceptable or does the main switch need uprating?

Thanks
Beeg
