Kitchen Wiring

[OnOff]

Hi, What is the "accepted" or at least a good method of going from buried 20mm PVC conduit ABOVE a worktop to 16x38mm PVC trunking UNDER the worktop. Is it just a case of putting a 20mm bend on the end of the 20mm then a neat Starrett in the back of the trunking? Hopefully the drawing below shows what I mean. 35mm box sitting 5mm lower than surface of the wall, 20mm PVC coming down from below the box then the trunking under the worktop. Thanks in advance.

Onoff, is the floor or ceiling of concrete construction? I only ask as I wouldnt ever use that method to install accessories buried in walls in kitchens.

So is this TW/E cable or singles?

Y are u using trunking/conduit and surface boxes are u trying to avoid using a rcd if so it needs to be be metal can't u chase the cables in or is that what the client wants sorry for sounding abrupt I'm only trying to work out y this method is being used

Nothing wrong with using conduit I generally use conduit rather than oval on rewires as its easier to feed cables and generally cheaper to buy. Also quite often will have surface stuff below work top if there is room.

Y not capping

Generally on rewires you want too plaster the least possible so conduit fits the bill capping is wider so chases need to be wider.
