Guys, I'm wiring a ten bedroom house which has 4 floors. Correct me if I'm wrong, but as fat as I know, new regs says to keep each room on a radial. So shall I keep each room on a radial or have a few rings on each floor after calculating the maximum demand??
 
i havent even started reading up on the 18th yet, is this going to be a thing?

how will adding into a rfc work with this set up if its true after the 18th comes out? would you have to run a radial from board for 1 extra socket?
 
Best you look at the calculations
... Where is the CU going to be?

Volt drop springs to mind

You haven't been reading the French regs have you?

Lol no!! I've allowed for a CU on each floor. Very big house! It'll save me alot of time and money running a few legs back to the CU to make it in to a ring. I might just wire them as radials.
 
Is that actually coming into force? Radial per room? That’s a joke.

Best idea ever. (If it's true). You are not looking at this correctly.
If the kids are not doing as they are told or spending too much time on their console you can isolate their room without affecting any other rooms. Everyone happy... Except for the kid who isn't doing as they are told..

What about the other circuits, lighting etc if it's a HMO?

Plus, all the circuits will be on rcbos so it's a win win.
 
Is it a HMO dwelling? Ah right see you have answered that question in the above post. Came through as I sent the question sorry Moaz
 
Yeh right calculate earth leakage! Also longevity of cable and who will be using it throughout it's life and how many times per day subject turning on and turning off, no problemo!
 
Anyway Moaz wire it how you like. You know the property and it's layout.

Just be aware of you cable lengths and do your calcs...and you may need to do 4mm radials if the property is that big..

R1+Rn (which you can get from Onsite guide)multipled by the rating of fuse you want to use multipled by the correction factor of 1.2 (70c)

Simple job done.

not if there are seperate CU's on each floor, depends how big the "floor" is though, it might be 10 small box rooms or david camerons house

Your right it could be very small :) but the OP is the one who's been there
I think Moaz said it was large, he didn't say if the DB on each floor was at the middle or the end of the house. So who knows how long the radial could end up being.
