I am about to wire my new extension, and would appreciate guidance on a couple of things I am getting hung up on. I would like to do the following setup, but am unsure if the 32a ring main is enough if there is going to be the washer/dishwasher/tumble drier on it 9kw = 35A or is this not bothered about?
1 radial to 2 bedrooms, 4 double sockets on 20a breaker via 2.5mm te
1 radial to fridge socket in new kitchen and freezer socket in old pantry on 16a breaker via 1.5mm te
1 ring rcd protected through garage socket all kitchen sockets and double in conservatory on 32a breaker via 2.5mm te
1 radial lighting circuit 2 bedrooms kitchen and garage on 6a breaker via 1.5mm te
1 radial to cooker (which will be gas anyway) on 40a breaker via 6mm te
I was going to wire the garage, bedrooms, kitchen and conservatory on 1 ring with rcd and another for the washing/tumble/dishw without rcd, but am trying to reduce the traffic at the consumer unit, hence the radial suggested for the bedrooms - can this be 1.5mm?.
Another question - I am coming out of the cu directly into the garage. Does it matter how tight the cables are together through the conduit between the garage and cu, and are they okay clipped to the wall within 150mm of the ceiling until they enter the kitchen or do they have to be in trunking?
