i know about ohms law! but with out knowing the excact voltage and the given resistance, i am unable to calculate the current, so 240v was just a general description.
you clearly have no idea about electrical protection systems in the domestic home
Nope according to you, but please explain.
its there to make sure any pipe work with in the property will be at the same potential if there is a fault, ie you have a shower with a fault and you touch the metal tap the voltage should be the same lets say 240v, no shock, if the tap was “earthed” you now have 240v passing through you and your in trouble.
As this intrigues me, Whats there ? So the shower has a fault ? What fault ? How does Main and supplemental bonding NOT Earth all your metal work in a bathroom ?
You sound like as I said early 1/2 right the other 1/2 is a country mile away and dangerous.
