HI All
There's a heck of a draft blowing out of my Consumer Unit ! I'd always known that the area where the CU is is a bit chilly - but it's suddenly dawned on me that there's a fairly large hole that connects the area into which the cables travel to the CU, and , eventually, the eaves of the house....
Net effect of this is that the wind's blowing out of the CU ! I'd like to stop this....
Now I know all about expanding foam and canoes - but I wondered if a carefully-aimed 'shot' of the stuff into the hole in the wall where the mains cables enter the CU would do the trick..... - but there's something in the back of my mind about expanding foam and PVC not getting on well together....
So - anybody know if they are safe together, or could suggest an alternative 'hole-blocking' substance. It's a fairly big aperture - lots of cables coming through it - ordinary mastic wouldn't do it!
I do realise that this plan of action would make life a bit complicated for anybody who wanted to add extra circuits to the CU - but I don't think that's going to be much of an issue...
Thanks in advance Adrian
