Geyser not on earth leakage

[ConcernedHomeowner]

Fascinating thread. I have a solar geyser and it's up on the roof of our garden flat (it's a 300l that serves the whole house and garden flat). It is currently wired through the Earth Leakage Unit (ELU), and with my intermittent Earth tripping, I have been advised that it can be removed from the ELU. I have seen what some people have said about the Zones, and it is nowhere close to bathrooms. I see that ACEsterhuizen says it should be on the ELU according to the 10142-2017. I have another ELU that was used for a Hot Water Unit that has been removed. I had other plans for the spare ELU, but if the geyser must be on an ELU, then I think that will have to do. I assume that later, when I reinstall the other Hot Water Unit, it can go on that same ELU as the geyser.

As quoted by Acesterhuizen(SANS 10142-2) all geysers must have earth leakage protection now, irrespective of when they were installed.

Hi

The regulations state that any fixed appliance must have an isolator within 1.5m or an isolator in the DB that is lockable.

The trend I see is to put a isolator in the DB for the geyser. In my opinion this is not lockable I know you can get a device to put on the isolator to lock it but not practical as I don't know of any r that does this.

More practical is too have the isolator in the ceiling next to the geyser.

Thoughts?

Where in the code does it say lockable and practical?

With most of the locking devices being cheap as chips, surely it's not an expense problem to keep some in your toolbox.

Hi Dave

Thank you for your comments, so then all circuit breakers are lockable?

Then the SANS should of just said an isolator within 1.5m or an isolator in the DB not a lockable isolator.

When I do an installation I plan for when I am not there so therefore prefer to have an isolator within arms reach.

Maybe I over think things to much, nice to have a forum such as this to discuss these points.

The wooden board DBs' often had isolators for geysers and stoves which were not lockable. Hence the regulatory requirement that it be within arms reach of the appliance or lockable in the open position when at the DB.

Locking devices for DB isolators might be cheap, but availability is another story. I requested a few at Voltex 20+ years ago and am still waiting for them. An isolator by the geyser is both safer and more convenient.

SANS 10142-1

Hi, just bought & down loaded a PDF copy from SABS - https://store.sabs.co.za/

Pop straight onto your iPad for quick easy access or print & bind a copy, only 360 odd pages.

Cheers

I was just wondering, as I am still looking for a pdf-copy of SANS 10142-1, does this document really have thousands of pages or hundreds of images???

What I can find on the Internet ranges from about 350mb to 1.5gb as a download.
Isn't it possible to convert it in a pdf-file with at most 2 digits of mb?

I am living on a farm and though I got a theoretical downstream bandwidth of up to 2mb (wireless), I cannot really download files that huge.

Maybe someone can sell me a second hand CD?

Thanks for your time.
