ring main

[huzzicuzzi]

hoping to put a ring main in only 3 double sockets on one wall
can i run the wire under the sockets back to the main board

Are you adding a new circuit? Do you require up to 30A/32A of power?
All concealed cables should be run in zones as follows:

yeah i just putting the ring main in my mates connecting to the board
i just don,t want to chip the wall all around the house whan i could run the cable back to the board under the other cable

 

[Spark123]

Sorry, I still don't understand what you are trying to do.
You say you are wanting to install a new ring main to power 3 double sockets, what do you mean by run the cable under the other one? Are you talking about running the cable under floorboards? What are these sockets going to be used for?

If you want to feed 3 DSO on the same wall, a radial might be better than a ring, IMHO

 

[huzzicuzzi]

sorry about that
the ring runing washing machine and dryer and fridge freezer
instead of going around the house with the cable back to the board
i was just wondering wether i could run the cable back the same way

Yes, you can follow the same route for the cables, although imho you may be better looking at running one length of 4mm² T&E as a 32A radial circuit.

thanks

Or can still use 2.5mm2 in a radial if you limit your MCB to 20A

Imho, 20A may be too close to the limit for running a washing machine, a dryer and a fridge freezer simultaneously.

Yep this is a valid point, but I just thouhght that this will give him another option and it complies with BS7671.

Not if the circuit capacity is insufficient to service the load it doesn't.

Not if the circuit capacity is insufficient to service the load it doesn't.

This is the first steep, if this is not verified, this remark is orrect for 32A ring as well.

AND if the units are in the kitchen than what...

What is not verified?
'this remark is orrect' ???
Have I just slipped into a parallel universe?

If you read the post I replied to you would maybe understand.
checking the capacity of the circuit to carry the load is the first steep.

What is not verified?

the capacity of the circuit to carry the load

'this remark is orrect' ???

CORRECT

Have I just slipped into a parallel universe?

I think you have been there all the time, come out...
