[Opinion] What type of wiring?

[123]

The first 3 pics, what type of wiring is that? I have never seen this before.
The 4th one, well all was done by a MIE and signed off....

looks like the old flat twin+e plastered straight into the walls...there is nothing wrong with using this and plastering straight onto the wall.

pinetown electrical started that type of cheap cr*p wiring in durban...in fact a lot of the expensive town house complexes are wired like that in durban. which just proves doing really cheap cr*ppy work wont put you out of bussiness because they are still around in fact they did all the work for woolworths group eeeish.

Hi 123,

If you're referring to the flat cable with an insulated earth it's a TPS cable, it's just a variation on the common ft&e cable. I've not seen it used in SA cause the regs don't call for earth wires to be sleeved or insulated, it's more popular in the UK and NZ. I'm going back a few years but the 2.5mm version used to be a multistranded conductor where the 2.5 ft&e here is a single solid strand. I'm wondering if it might be slightly higher current rated than the standard ft&e?

*Edit*
After saying that when I just scrutinised the pictures closer it actually looks like a low profile conduit with housewire pulled through it. If it is conduit you should check to see if it's SABS certified.

That board also looks like there is two separate live supplies. Just watch your eyebrows, you might need to find two pointsto isolate it from :-)

As far as I know you are not allowed to plaster twin & earth directly into the plaster, Surfix yes.......did I miss something?

Thanks for the heads up.

Indeed there is 2 separate live supplies, feeding from the one phase of the 3 phase point of supply. The 2 incoming wires, which is actually part of the 1 phase, feeding from a 3 phase supply, splitting the one phase into a 2 pole isolator, which in turn is feeding the rest of the DB and loads.

Had to call Mnengse, our local "key" guy to make sure.

Welcome. Glad to hear you still have your eyebrows :-)
