I want to help a youngster but do not know who/where he can contact the correct person, he is in Alberton.
All comments will be appreciated.
Thanks

I don't know how anyone else is going, but I got gateway timeouts trying to download from those links.

Sparks sent me the pdf - I've got it down to 300dpi and it's now 993KB available at https://www.theforumsa.co.za/documen...-scan-tfsa.pdf

Hope that helps.

I'll pass it by my wireman for some feedback too, but I did notice a few things that surprised me:

Why would you use a calculated PSC on a single phase supply? Use a PSC tester for crying out loud.
How can you issue a COC on an installation where your PSC is higher than your short-circuit/withstand rating?
Section 3 - description of installation... Ja, about that one

nothing wrong with that its not part of the installation because its plugged in

Yep - when I saw that photo I started wondering about the plug/junction box in the earlier photo too. How is that supplied?

I have some concerns about some aspects of how the electrician that issued the COC went about his/her business, but ultimately the COC only covers the portions of the electrical installation it was issued on.

You can contact the ECA in Gauteng on 011 392 0000 (Jhb) or 012 342 3242 (Pta). They should be able to point you to one of the GEIA chaps - I believe there are some in Gauteng.

When it comes to the parts of the installation where no COC has been issued - there I think you'll have to be chasing the seller (if this was a sale situation).

6.16.1.1 Fixed appliances do not form part of the electrical installation
other than their positioning in relation to the supply and the wiring carried
out between different parts of the appliances.

I always believed that the plug-top is part of the fixed appliance and therefore the wiring from it to the heater would be included in the COC.
Exactly the same rule can be applied to the gate motor which is plugged into socket outlet in the garage, it still requires a disconnecting device withing 1.5 meters of the motor.
