afternoon
i have looked at a property, concrete floor/ceiling and customer want additional sockets in some rooms. in each room there is 1 socket 300mm from 1 corner of the room,the customer is asking for additional sockets.I intend to run around room in a new boxing which is to house radiator pipes ,and will allow for additional temperature. my question is the existing socket are at 450mm from floor and as such the cable will need to be run horizontily from socket into the corner and change direction down.
the cables will change direction with in the 150mm safe zone of the corner ,is this compliant as I would normaly have a box at the change of dirrection but this is not acceptible with customer ,circuit is to be RCD protected.
thanks in advance

Yup.


Given that CH pipes can run at above 70 degrees ... that might be interesting!

Can't you simply go horizontally around the room?

- Andy.

Insulating the pipes whithin the boxing would be worthwhile,

Dave.

pipes shall be laged and a compartment at the bottom formed.the circuit is a ring so I have calculated cable using 21A,
I have used ref B (4D2A)
and factored for 50 degress temperature (table 4B1).

which comes out as 4.00mm T&e

does this sound OK can any one see a floor in this, i know it will be tight in the sockets.I will investigate possibility of a horizontal chase across wall but they were not to happy.

cheers

Do you really need a 32 amp rated circuit?

Regards

probably not but I intend to put on a 20A but wish to future proof against them wanting it as a 32A
