10 Bedroom house rewire. Ring or radial?

[Moaz]

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??

What new regs are you referring to Moaz?

Not in force yet, wire your house to comply with the 17th

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?

 

[elsparko]

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?

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.

HMO ?

Is that actually coming into force? Radial per room? That’s a joke. Unnecessarily filling up the DB..

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.

It's domestic. All circuits will be on rcbos.

 

[Pete999]

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

As far as I've understood. It's true, unless someone can correct me.

Ive read the 18th draft and didn't see that one. Where did you see it Moaz?

Seems an odd move if they remove RFCs completely. I can see how they might recommend radials in certain cases, but surely it's better to keeps RFCs as an option.

same here.

Maybe I misunderstood. I'll check it tonight.

Where will you be checking tonight? Where did you see it originally?

Originally another spark mentioned it. And a few weeks later, I heard someone else mention it too. I've not checked the draft myself, but I need to now.

 

[Spoon]

This is what I have as info.

not true.

But we will have to take into account earth leakage when designing circuits.

Not sure how to do this!
