First of all it has no provision for RCD protection to your shower which is required by the regs.
I have a seperate unit/switch on the board for the shower rated 30ma with a 30 amp fuse in, shower I am looking at putting in says "We recommend the inclusion of a 30mA residual current device (RCD). This may be part of the consumer unit or a separate unit" so it looks like I have that covered
"The appliance requires a 40 Amp supply fuse" could someone explain this for me
More like 4.0mm².
maybe 6.0mm² at a push, but I don't think so.
Will measure it tonight but would say it looks more like 10mm
