Some may remember my question from a week or so ago about fitting a
gas meter box. I have fitted the box and it all went fine, no
calamaties with the whole wall collapsing and it has turned out pretty
neatly.

My next question relates to the earth wire which must be run to a
point just after the meter. Do I need to sleeve this wire as it comes
through the wall or will the PVC coating suffice?

Thanks
