Move switch

[taffyboy]

I have moved a light switch from one side of a door to another
Do I need to protect the cable or can I fill/plaster around it

Thanks

differences of opinion on what you should use, but either trunking or capping before you plaster over the cable

And take it all the way to the top of the wall, along near the ceiling (about 3-4cm in) then STRAIGHT down to the switch)

Otherwise someone will only go to put something like a clock above the door, and nail straight though it.

Idealy, you would take up the floor board upstairds directly above the switch, pull the wire all the way out, then feed it down in line to where you want the new switch position to be.........


Yup capping is a min, conduit isn't essenial in a sold wall for a light switch, but many people have a personal preference.

just out of interest is this simply to protect from accidental damage or will the plaster corrode the cable?

Plaster will not damage cable.

In theory the protection is to stop damage to the cable when plastering takes place.

wasn't there a post on here where some one mentioned that plaster DID "corrode" a cable?

Not seen the post your referring too, but there is a school of thought that believes that plasyer does damage PVC cables, especially LSF types.

Apparently plaster leaches some of the plasticiser out of the PVC making the cables brittle over a period of several years.

I have no idea how accurate this train of thought is, but considering the fact that capping is cheap, it is better to cap and be confident of no problems than not capping and face the potential of problems later down the line.

It is also good practice as the cable is less likely to be damaged

It's all horrible - I much prefer conduit through which cables can be pulled at any time.
