Valid COC?

I think I'm going to bomb those links to those monster files and save everyone some serious bandwidth, Sparks.

And yes, now I understand why Sparks is getting hot under the collar on this one.

Thanks Dave, you certainly are on the ball. Much appreciated.

Maybe they can prove it to us?

Prove which bit, the single phase rotation or the no geyser?

We always mark the rotation as not applicable if it's a single phase supply. I've never had any guidance to say we should do otherwise but not working in the domestic field we only issue maybe one COC a month so maybe it's slipped through the net. I would carry on doing this unless someone can show me firstly how to determine the rotation of a single phase supply and secondly a good reason to worry about it.

I've never seen a domestic property that doesn't have a geyser. Also if there's a gas water heater there's more regs such as the cage for the bottle requires earth bonding and lightning protection plus they still need the earth service bond to the water pipework.

The rotation of 1 phase around itself

The geyser is still there

I have just heard that there are another two powered-up DBs'

I was hoping there is an ECA member in the Gauteng area with a contact number for someone there. Here is another sample:

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).

Thank you Dave,

I just need to backtrack a bit now though. Murdock, I agree with you in some cases, not this one however. The underfloor heater is a fixed appliance and as such is required to have a dedicated circuit fed through the ELCB with either a double pole isolator or be fed through a socket outlet for isolating purposes. The socket outlet is not there to discount the heaters from the COC but rather as an alternative isolating mechanism. If the heaters are excluded, does it mean that the earthing mesh is also not required? Is the floor heater exempt from the regulations completely because an alternative "isolator" is being used?

how do you know the under floor heating was installed before the COC was issued? you just never know...

something we must all remeber is maybe this person is not out to crook the system maybe this person just needs some help...pointed in the right direction...i still dont get this COC thing right every time i am lucky to have a very knowledgeable person who assists me when i need help...

after attending a refresher course at the eca i realised that this industry needs more teachers...and because of the amendments...refresher courses or a point system should be bought in to make sure we all keep up with the changes.

i for one would attend seminars or group meetings to discuss problems we are having in the industry and to address confusion with certain parts of the regulations...

This COC was issued after the house was sold before the new owner had access. I somehow doubt you will install underfloor heating after you have sold your house.

I have highlighted all the items I have an issue with.

This guy does not know how to complete a COC
This COC is worth less than toilet paper.
At least toilet paper does not give paper cuts.(not what I use anyway)
