Switched Fuses

Is it OK to extend a 30amp ring main to accomodate two FCU\\\'s and is there any height restrictions?

The purpose is to install two wall mounted LCD TV\\\'s which fit close to the wall and using 13amp plugs would be a bit restrictive.

Thanks.

yes, you can continue the ring to FCU's. there are recommended height restrictions, but i wouldnt worry too much if there behind the TV

Subject, of course, to permitted routes for the cables or adequate mechanical protection........

I live in a bungalow so routing is not a problem but what do you mean by mechanical protection?

cables must be in certain areas or be protected by earthed steel conduit. search.

Burying cables in plaster:

either you have to run the cables vertically or horizontally from the accessories,

OR if this is not possible,

provide mechanical protection from drilling - earthed metal conduit, or bury cable 5cms from the surface.

but by the time you get to this depth, your usually less than 50mm from the other side of the wall

exactly, its not workable for most situations. And if you are going horizontally 5cm deep in a solid wall, consider the structural integrity of the wall . . .

one wall in my house isn't even 5cm deep . . . . dead thin, soft breeze blocks

very long drill bit. dril straight down from above, keeping it at least 5cm from each edge. think you could do it? no chance.
