Geyser earthing and bonding

[GCE]

The toppies needs to have headlamps when called out at 2am in the morning the point i am trying to make is you wont know about an earth fault if it doesn't go through the RCD and that is a safety risk to owner changing a light bulb or to you as contractor.
Why would you need to change a stove every 6 months should it be RCD protected are you now going to change your geyser every six months because it is now RCD protected. All my curcuits in my house has been RCD protected for the last 25 years and i had very few "nuisance tripping" issues but on a few occasions when it tripped it was a pot boiling over on the stove(solid plates) that it is a good thing right it protected my wife in that instance. Oven element did trip RCD after 15 years because it needed replacement. The safety factor protecting all curcuits outweighs the discomfort factor.
In your last paragraph you seems to suggest that i was disrespectful towards GCE not at all i simply saying we all learn every day unless the toppies feel they don't learn anymore by the way i am also in the toppie crowd. But still where this all started a few presentation slides posted now i am made out to be disrespectful. I am sure i will be learning a lot of new things in this forum from GCE and other toppies and non toppies
Peace ✌️ out brother all good

RCD were originally introduce to protect portable appliances especially the leads to portable appliances because the risk was always there that the earth connection could come loose or some that did not have an earth.
The rcd would pick up an imbalance on live and neutral and trip.

Fixed appliances and general wiring don't have that problem and if earthing is carried out correctly there is absolutely no reason to put them on RCD. On an earth fault the circuit breaker will trip.

According to my sources the RCD on a geyser was strongly motivated by one person sitting on the technical workgroup and that person should have retired long time ago from the industry
There was no need to put geysers on RCD , the only time it becomes a problem is if the earthing is incorrect.
