there is a possibility where there is an open circuit neutral, for all the exposed/extraneous metalwork in the installation to become live at mains voltage. .
Neutral on the pole outside corrodes, and goes open circuit or high resistance.
Loose connection within service head, arcs and sparks, goes high resistance.
Tree falls, and severs the bottom neutral on a pole (missing the top 3 lives).
list goes on.....
In theory yes, but it aint a reg.......so.......?
So you have lost neutral and therefore also earth and all there is indoors is a potential of 230V and no path to earth. How does connecting the incoming gas and water to the MET make things safer. (Bare with me, penny has not dropped on this one yet)
If you don't bond the incoming water and gas then the neutral and earth conductors will rise to full live potential, the pipework will remain at ground potential. Touch both at the same time and you get a nasty (potentially fatal) shock.So you have lost neutral and therefore also earth and all there is indoors is a potential of 230V and no path to earth.
