Hi,

Is there a maximum number of sockets that can be fitted to a 2.5 ring?

Do the cables have to be further protected if chased into plaster and tiled over?

Can a dual fuel cooker be vented up an existing chimney?

Any advise would be appreciated....Thanks

unlimited for a ring, but the floor area is limited to 100m² (this is unlikely to be exceeded in a house)
Do the cables have to be further protected if chased into plaster and tiled over?
providing they are in certain zones (up/down/side of accessory, 150mm of corners and ceiling - search for more) then they dont need protecting. but its a good idea to use capping/oval conduit to protect from plasterer and make renewing easier. other areas they must be protected by earthed steel conduit or be buried 50mm
Can a dual fuel cooker be vented up an existing chimney?
not sure

Thanks for advice.

One more question...To link the sockets above a work service can I run the cable horizontally below work top height?

Thanks again

If they are buried in the wall, then no, not unless they are horzontally in line with the fittings (you can't drop down a foot, go along a few feet and come back up a foot), however if they are just clipped to the surface and the cupboards in front, then yes you can (as people can see where they are as to not drill a hole through it)

Hi again,

If I understand correctly the cables can be run under the tiles, he tiles giving protection from nails etc.

Is this interpretation correct?

andy · 3 Feb 2006

tiles dont give protection....

if they need protection, it must be by earthed steel conduit

Steve · 3 Feb 2006

Hypnoman, either the cable's route must be clear (direct between accessories, where no sane person would drill), OR you must provide mechanical protection in the wall - earthed metal conduit being the norm.

The idea with earthed metal conduit is that when you drill the metal and the cable, it provides a massive short circuit so the fuse/mcb blows quickly. It takes skill to install this though, it is not often used in homes nowadays.

Tiles aren't going to qualify as protection im afraid - people do drill through them too, and I dont think there's a way to earth ceramic or clay tiles . . . .

...or run along the surface in trunking. (below worktop height).

If you're putting sockets above a worksurface, I think it's great to put plenty of them in, with the ring running horizontally from one to the next. Very economical on labour and meterials, amf if you've run it in oval conduit or under capping you can easily add another socket or FCU in the row later.

Foolish boy! You forgotten to include a 20A DP switch with neon every 60cm to feed appliances below the worktop!

And I said a single row.

But your method saves on plastering.
