Are mains electrical cables channeled through the wall or dropped down the cavity (plastic conduit)

Question

Referring to new houses in the UK.

Answer 1

NEW UK homes wires are usually behind the dot-and-dab plasterboard.

They are not permitted to run in the cavity. (although they may run THROUGH it).

Examples of the risks being;

Damp penetration (bridging the inner & outer leaves)

Damage to sheathing from sharp edges (wall ties)

Answer 2

if they are not DIY(could be any cowboy job)

a general(and should be by any legit electrician)rule of thumb is the wiring for lights comes "DOWN"to the lights from above,,and wiring for plug sockets should come "UP"from the floor below,,,but be careful as they may have been installed by cowboys,,

you can take it that the cowboys have voted here 4 downers from 4 a**eholes

Answer 3

the definately should not be inside the cavity, and  they require to be inside earthed metal protection if inside the wall if they are less than 50mm deep or else protected with their own RCD , also this comes under the building regs so It is law.

Answer 4

electrical cables should be in a conduit for ease of renewing the cables and also because some cable coatings react with cement and/or plaster...

loose cables in a stud wall are fine but again should really be placed in

conduit for ease of service ability and then you can bury them in the walls...

put it another way if they are not in a conduit and should they ever need changing then you are going to have to rip open the walls to change it...

Answer 5

Your question is scary. Please check with your local Hydro for code that you should follow...me thinks that you are not up on your knowledge about electricty and the damage it can cause...
