practical need for supp bonding in bathroom

wallywombat
Can anyone suggest a realistic scenario where supplementary bonding would be required in a bathroom or other 701 location? I'm failing to think of one, although I may be overlooking something blindingly obvious.


It can be omitted as long all three of these are satisfied: ADS in time; RCD present; any extr-c-p connected to main bonding.


If ADS can't be done in time by either MCB/RCD then its not legal anyway.

RCD has to be present anyway.

Water and gas pipes etc should already be main bonded if they introduce a potential.

    If, as you say, the chrome pipes are connected to plastic pipes above then they will not be Extraneous-Conductive-Parts so should NOT be bonded. It wouldn't be bonding anyway; it would be unnecessary earthing which is not a good thing.


    The macerator, shower and fan will be plastic, I presume, so that just leaves the radiator as an Exposed-Conductive-Part with nothing to bond it to apart from possibly the light and the water heater.

    Do the light and heater have any Exposed-Conductive-Parts?
