Coc for 12v down lights

[Pietie Badenhorst Ct]

Hi guys did a Coc for a house a month ago, all lights was working. But now I received a mail stating that another electrician went trough the house and found that some of the lights transformers was not working. Is the transformer part of my Coc?

No.

We test the wires not the appliance. So if the cabling is fine then you good.

People want to be smart and not pay and blame others.

Tell that spark to read the Sans book and stop trying to impress the client by putting others down.

Light fittings are excluded from a COC besides the safety factor - It is written as such under the notes in the beginning of the Test report - Note 3 , I think

Perhaps some clarity is needed in case someone gets to this thread for other forms of extra low voltage lighting...

My understanding is that if each transformer supplies one luminaire each, the transformer can be deemed part of the luminaire and the point of consumption is the supply side terminals of the transformer.
However, where a transformer supplies multiple luminaires, the transformer becomes part of the electrical installation and the point of consumption is the connection terminal of each luminaire.

Subject to confirmation by the experts.

That is an interesting thought.

I see what you saying Dave.

I am not sure what to make of it now.

I don't think the transformer that feeds multiple lights is part of the appliance, but if you take it away the lights won't work.

That would mean getting in the roof to test to the transformer and then testing from the output to then each light for example IR test.
