I have a gas supply and boiler just outside my house in a garage that is not part of the house structure. It is a felt-roofed building with an up-and-over door next to my kitchen. The gas never enters the house - only the water pipes from the boiler come through the 15"-18" of solid stone wall. The gas supply has no earth strap at all. Do I need to run a 10mm2 cable from the MET outside my house to meet present day requirements?
Secondly, if this is necessary, I may have to poke the cable through the same hole as the hot water pipes, that reach up to 80C. Is it acceptable to route cables in close contact to hot water pipes like this?
