Many thanks.
Excuse my ignorance but what is "PV cable" (Photo Voltaic?) and where does one find the official ratings for theses cables?
I would like to know the rating for 2.5mm flexible cord
Many thanks.

To make a mistake is human, to learn from that mistake is knowledge and knowledge is strength.
This is the cable we use...

Thank you for this but I am looking for the ratings for 2.5mm flexible cord. The above links only give the ratings for flexible cables which are 4mm and largerOriginally Posted by Isetech

Check 10142-1, I don't think fine stranded can be less than 4mm2

The following mentions flexible cords which the definition describes 4mm or smaller, or am I misunderstanding this definition?
6.1.11 [I]Where flexible cords are used as part of the electrical installation[/I], 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.
The definition of a flexible cord is as follows
3.8.2
flexible cable
cable of which the conductors consist of strands of diameter not
exceeding 0,51 mm and of which the insulation and covering are such that
they afford flexibility and in which the nominal cross-sectional area of each
conductor exceeds 4 mm˛
3.8.3
flexible cord
cable of which
a) the nominal cross-sectional area of each conductor does not exceed
4 mm˛, and
b) each conductor consists of strands of diameter less than 0,31 mm
My understanding of this is that cord (cabtyre) of 2.5mm with fine wire is allowed. Or am i missing something?
However, SANS does have amp ratings for flexible cables but not for flexible cords. Not sure why

By the way this only applies to terminations where old screw type breaker and connector blocks it is not required for the new type of breaker terminal. We still use bootlace ferrules for pushin type connectors.
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.

I think this is going off at a tangent. I have always and still believe that the flexible cables refered to in SANS are those which form part of the integral wiring of appliances. Between hob, oven and control panel for example. Just my 2cents worth, I will stick to hard wire. Call me old fashioned, I don't mind.
