Right I have only limited electrical knowledge but I need to find out the best way to go for the installation of a new shower.
The Shower is a 10.8kW
Firstly 10mm or 16mm cable? Walls are cardboard lattice type insulated.
Secondly my 100A CU is a crabtree unit. The MCB should be 45A - the only option for my existing unit is 40A or 50A - is it safe to go to 50A?
The MCB will be fitted into a spare slot along side 32A ring socket circuits on the RCD protected circuit (63A 30mA) - is this okay?
I don't think the existing Type 1 MCBs are still available (house about 15yrs old) - will an up to date type B crabtree MCB still fit? I do not want to go separate block for shower to keep cost down.
Any info would be appreciated.
