Hi,
I've been asked to install 2x9.8kW showers in a domestic dwelling. I realise they will need 2x 45A MCBs in a 100A/30mA RCD enclosure (no space in current CCU. However i've calculated this will require over 80A (can't apply diversity to showers). Therefore seeing as there is a 100A BS1361 main fuse, i would think the possibility to overload the main fuse is quite high, especially in the morning when kettles, toaster, ovens etc are possibly on at the same time as the showers.
Your help would be gratefully accepted. Many thanks
