I am extending an existing ring main to provide more power points in a first floor ( upstairs ) bedroom.
I have successful expereince of this , but some years ago and just just wish to check a couple pf points re current regulations.
- In a first floor situation is it ok to just lay the cable in the void between floor (boards) and downstairs ceiling ,
or does one have to fix (pin) cable to the sides of the floor joists. ?
2 . Sunken socket boxes will be about 12" above floor level , ( about 6" above skirting height)I have cut chases in the plaster down to brick suface.
Is it required to use trunking for the vertical run from floor to socket box ? I would use PVC Oval if I had to but given the shallow depth of the chase I would rather just plaster over cable if this is OK.
Thanks in advance
Richard
