Thanks

Thanks, I understand. Why then, would a 10mm2 cable be recommend with a 40A trip (in the shower manual)?

Yes it has RCD protection. It's an MK Sentry unit. Thanks

Sorry if this is a stupid question but I imagined the cable would be critical in the sense that if it's too narrow and the MCB has a high rating, it would potentially melt/breakdown before it trips? i.e. I presumed you would not put a 45A MCB on a 6mm cable. Thanks

I'll have to find the routing of the cable as it could run down between the plasterboard and the outside wall which will likely be insulated. I presume that's what you mean by thermal insulation? Thanks again.

I have had a 9.5kW shower installed for a few years now. The wire is 6mm and the MCB is 32Amp. I noticed on the shower manual that the recommended MCD is 40Amp and also strongly recommends that any shower greater that 8kW uses 10mm cable. I don't know how risky this is. The lowest equivalent...

Thanks. I'll investigate further and decide which is easier.

Thanks everyone. Much appreciated.

See attached. Thanks

Thanks. I was hoping it could be added from the downstairs switch as opposed to running cables from the top landing light.

No light on the bottom landing.

I have a light in the top landing which is wired for two way switching from the top and bottom landing. I would like to add a light to the bottom landing operated from the same switches. Anyone have a diagram for two lights running from a two way switching circuit? I presume I will need to...

Understand. Thanks for that.

Thanks guys, this is reassuring. I can't say I fully understand why but guess it's in the mystics of how RCD's detect unbalanced circuits.
