Why do electricians never allow enough slack on loft cables so they can be raised above 300mm of insulation. Its not as if 10”-12” of fluff is the cheapest and quickest way to meet a government requirement, oh wait… I’m not too fussed about the lights, low load, yadda, yadda. However the electric sockets for this room are distributed via the loft not under the floor. I’m not sure if it’s a radial or a ring main circuit. One of the cables has actually been fed through a hole in the ceiling joists. This seems like complete *******ery to me, when all the other cables are laid above the joists. As well as the unnecessary damage to the joists it makes it difficult to lay the insulation as there’s a 50mm gap between the cable and the ceiling. I either squeeze the 100mm loft roll under it and lay 200mm above it or just put the full 300mm over it leaving a small air pocket under the cable. As I understand it, the cables should be in contact with a surface like the ceiling or a joist OR they should be open to the air so as not to overheat. Although you would normally consider a bedroom to be a low electrical load room – I must consider the use of more than one high load device: hair dryer, straighteners, curlers, rollers, iron etc. I’ve slapped 100mm of roll over it for the moment as it was bloody cold without it but I wonder what is ALARP before I put the other 200mm over it?
