Twin + e 2,5 mm price

[ians]

Prices including vat

Builder price R25 per metre

Local wholesaler :


1 = R18.90

2 = R23.35

and we complaining about the fuel price

That's a R445 price difference

I thought the salesman was ripping me off ... so I contacted another branch ... same price.

Copper prices have gone through the roof.
PC Board prices have shot up as well, since they are claded by a copper surface.

I just got a price of R865 for a coil 100 m of 2.5 mm twin+e (free delivery in JHB) apparently it is not copper ... then the guys offers a price of R1685 (100m) it is tinned copper but her cant offer SANS approval ... SANS approved twin+e is more expensive.

A simple question how do you know if the wire being installed on your property is SANS approved ?

How do we know if any product is SANS approved. Its just a logo...

So with that said I will check the packing and product and I also buy from reputable places and brands. However there is only so much I can do and I like to think the suppliers I use get the real macoy aswell.

But back to cable... its so expensive and when you add the markup the client thinks you taking them for a ride...

There is also this safeashouses thing which seem to do all the quality control of products. i don't know how it is done 100% but if that logo is on then It adds that bit more trust

Hello Brother

I think you might have meant SABS approved.
The product does not need to have the SABS Approved logo on it to be approved.

It can either have the logo OR the seller must be able to provide a Letter of Authority for the said item.

SABS or SANS ?

Anyone tried bending 20 mm PVC pipe recently?

I wont be wasting my time ... I suppose who bends conduit in 2021 ... maybe that why the wall thickness and has been made much thinner.

ALL conduit bought anywhere in the Transkei, cannot be bent. It cracks. Hard plastic. Cheap Chinese junk.

The conduit we getting is still kiff. Bend a lot, no problem.

Hi

The surfix and Twin and earth , steel coated copper is not SANS approved for house wiring - The volt drops across the wiring are way out of specification - It is being sold in " General Stores" and a magnetic quickly identifies the cable

The supposedly T&E is brought in under SANS1507 and called speaker wire
Sans1507 consists of 7 different parts ranging from housewire to service cables and I assume that one of them is speaker wire
I don't think the steel copper coated wire would work to well on speaker wire either

What does this tell us ... it has become an even higher risk to sign off a COC in and existing premises ... once that twin is installed and plastered into the wall you would need to go around and check every single wire in the installation.

We back to public awareness ... people are on a tight budget ... it would make sense to use a person who can install a plug point for R500 including 50 m of twin ... the plug and box ... if you paying R2400 for 100 m of SANS approved wire ... you know you something is wrong.

[ians]

It seems we have reached a point that we would require every item bought would require the document for the material installed to prove that is is sold for the application and that it has approval.

I dont think people understand the implications of signing off a job with non compliant materials ... they do ... they just don't care because we all know we play a numbers game and the odds are in your favour ... the chance that someone might actually go out and carry out an investigation is so small that it is worth taking a chance.

If you can get away with running house 1.5mm house wire connected to bare overhead power lines ... hanging across the road into the bush and supply an entire informal development ... what are the chances you would get caught installing speaker twin wire that looks just like twin+e ?
