UK Running central heating pipe past electrics?

[kristeva]

Hi all

I need to run this CH pipework to a radiator located beyond the electric wiring in the image below.

Just to be safe I was wondering if there are any rules / distances, etc I need to be following when avoiding the wiring?

Many thanks. P

There's some rule - like 25mm or so.

Just move the wiring and clip it as far away from the heating pipes as you can with at least a 25mm space.

You don't want a situation where the heating pipes melt the insulation around the electrical cable.

The rules are more applicable to the rating of the current carrying capacity of the pvc cables. The maximum current rating of a pvc cable is based on the copper conductor attaining a temperature of 70 degrees C. If your water pipe temperature is approaching 70 degrees then there's every likelihood that the cables will fail being in such close proximity. Ideally either the cables or pipes should be moved away from each others sphere of influence. If this cannot be done suggest you fit insulation over the pipework to minimise heat transference, DO NOT repeat DO NOT fit insulation over the cables as this will impair the cables ability to remain cool when carrying rated current.

Those pipes need to be further away from the cables. The cables were there first
