running cable near copper pipes

[MJM]

I have to run some 6mm cable behind some copper pipes to a cooker switch and socket on the wall. Obviously I can't chase it into the wall behind the pipes, so is it acceptable to put an extra piece of cable sheath between the cable and the copper pipes to protect the cable?

Thanks.

can't you put some mini trunking round the cable?

what pipe is t? if its gas then it has to be run at least 25mm away, OSG pge 18

 

[MJM]

It looks like gas and water pipes, 4 of them all running parallel. Shall I clip the cable to the wall above the pipes and then chase up to socket instead?

 

[telectrix]

where are these pipes. vertical, horizontal, just below ceiling, floor level?????

 

[jase]

do what you want aslong as any electrical cable is 25mm from a gas pipe

 

[MJM]

The pipes are horizontal about 400mm from floor. They will be hidden behind kitchen units.

Thanks I'm best clipping above the pipes then cause there's no way I'm going to get it 25mm away if I go behind. I wonder why they specify for gas but not hot water? Would have thought hot water pipes would be more essential!

I don't think hot (or cold) water goes with such a bang when there is a spark!

I believe the 25mm min distance can be reduced if you interpose a non-conductive barrier between the gas pipe and cable, or wrap the pipe in PVC.

Look at the OSG page 18.

A length of trunking usually does the trick.

if the pipes are hot water, clip cable below pipes. why? because heat rises.
