Question regarding single phase electrical wiring of premises

[Derlyn]

Just something regarding cabtyre flex.

In previous editions of SANS 10142, the use of flexible cords in an installation was illegal as per the wording of 6.1.11. which stated that "flexible cords shall not be used as part of the electrical installation"

However

In the new SANS 10142 -1 Edition 3.1 the wording has been changed. It now reads "Where flexible cords are used as part of the electrical installation, the selection, installation and colour identification shall be done in accordance with this part of SANS 10142"

So according to the above, cabtyre flex is now permitted as long as the colour coding is adhered to and according to 6.1.12, bootlace crimping ferrules must be used to prevent strands of the conductor being cut off in terminations.

Just a bit of clarity regarding the regs and the use of cabtyre flex.
Hope this helps.

As you can see from the photo, bootlace crimp ferrules was not used.

Correct. Also, most cabtyre has a blue conductor for neutral. This must be changed to black, using either tape or heatshrink. Neutral wires MUST be black.

GCE covered most of your query, but I just thought I'd mention the cabtyre issue as a large proportion of electricians think it's illegal to use on an installation, but according to the latest regs, not so.

Seems as if you got a raw deal.
Some people have no scruples.

So just to verify

the exposed ends of the neutral that is exposed from the white casing, needs to be marked black (heatshrink or tape) at both ends of the cabtyre?

Yes.

Reg 6.3.3.2 (1) A neutral conductor shall be identified by black only.

There is twin flex used - which is a definite no - Also no cabtyre under 1sqmm

6.1.11 Where flexible cords are used as part of the electrical installation, the
selection, installation and colour identification (see 6.3.3) shall be done in
accordance with this part of SANS 10142. Flexible cords with cross sectional
area less than 1 mm2 shall not be permitted.
6.1.12 Where flexible cords are used, the strands of the conductors shall be
mechanically protected with ferrules to prevent the strands from being cut off
in terminations.
