I have been told that the earth connection to my consumer unit, older mcb unit, is inadequate. The company supply cable has exposed multi wire sheathing, i would say like armoured cable, and a clamp has been fixed around this to which an earth wire is fixed. I assumed as the cable then goes underground it provides earthing. If this is now said to be insufficient, and i cant think why that should be, what else can the earth wire be clamped to. The water pipes are no doubt blue plastic and i think gas is now yellow plastic so what is the answer?
I noticed at a friends house the similar calmp had been removed and a wire was in stead connected to the gas meter inlet pipe??
A bit of advise would be welcome...thanks.
