consumer unit Ask questions and find answers to many subjects relating to electrics and electrical work

[pc6844]

Hi, i have an old standard type wylex consumer unit the one with the pull out fuses fixed into the exterior wall. More or less directly behind it on the outside is the electric meter. The cold draft on the inside of my house from the consumer unit is unbelievable and i wondered if i can insulate the holes from the cable routes from the meter to the consumer unit with expanding foam or insulation?

Many thanks

I have seen a similar question asked and the answer given that seemed best was to fit a cupboard around it.

I said with that post to do anything which could cause the cables to overheat would of course be dangerous. If some one with knowledge could inspect it they may say that form filler is OK but needs to be seen first.

Tails for a 100A supply are normally around 25mm CSA but with old houses I have found down to 6mm CSA and pictures don't help in identifying. It would be dangerous if the cables were under size as well.
