Hi all been requested to install a shower into house first time I have not had spare fuse in situe normal just stick to upgrading replacing current systems ins fuse system is BS3871 no extra fuse in spare slot so the obvious choice is installing a second consumer unit.
I reckon the system is a TN-S system see picture attached.
looking at adding Henley blocks 25mm tails from meter side to both consumer units and 16mm earth to earth block.
The 1way CU will have 63amp RCD and a 40amp for the 9kw shower.
10mm cable to 40amp double pole switch installed in cupboard.
Obviously the main fuse will have to be pulled for safety. Is the above the only option to me or is Thier another option without pulling the fuse that will still comply to BS7671 and be safe.
Any advice is much appreciated
