"wire a house in cabtyre", really?

Yip ... read all the comments ... and the new regs ... it seems the SANS regs have evolved due to low cost housing and ready boards.

For the testing of installations that are fully or partially in hazardous or
specialized locations, see the relevant standards, and complete the additional
report(s) (see 8.7 for hazardous locations) and the SANS 10142-1-1 test
report for medical locations. Amdt 1

8.6.2 Continuity of bonding
Confirm the continuity of the bonding conductors between all exposed
conductive parts within arms reach (or see annex A) of each other. When a
test device or instrument is used, it shall have a supply that has a no‐load d.c.
or a.c. voltage of 4 V to 24 V, and a current of at least 0,2 A. In each case, the
resistance shall not exceed 0,2 Ω. Amdt 1

8.6.7 Earth resistance
8.6.7.1 Earth resistance can be determined in accordance with SANS 10199.
NOTE Where the supplier does not provide an earthing terminal or where an
alternative supply is installed, the efficiency of the earthing system can be confirmed by
this test in SANS 10199 or by using an appropriate instrument. Amdt 1

b) a socket-outlet that complies with SANS 60309-1 (industrial type) with
30 mA earth leakage protection, however, the use of industrial type socket outlets
is not recommended for stove connections.

What is stopping you from using an industrial type socket outlet as mentioned above?

Not recommended but if you cant fit the real thing ... well sometimes you have to do what you have to do ... personally I could see myself fitting a huge industrial plug or stove connector for that matter behind the stove.

8.7 Test reports
The following test reports are applicable:
a) Test report for all electrical installations, excluding secondary reticulation,
NOTE This report may be supplemented with the additional report for a medical
location. Amdt 1
b) Test report for secondary reticulation per 7.16,
c) Additional test report for electrical installations in medical location in
accordance with SANS 10142-1-1, and Amdt 1
d) Inspection and test report for electrical installations in hazardous locations

It quite handy having 3.0 and 3.1 in pdf ... you can tile them and scroll down to see the amendments.

You would think they would check the document for errors prior to releasing them

Ians you are a hero! Thank you! when ever we cross paths a lunch is on me.

I'm confused here. This morning I go to buy the latest SANS 10142_1:2021 (ED3.01) and I am faced with the following two choices.
1. SANS 10142-1:2021 (ED3.01)
2. SANS 10142-1-2:2021 (Ed 1.00)
What is #2?

With regards to using cabtyre in electrical installations ... I have found on many occasions that people use a 3 core cabtyre to connect a PEC ... the brown/ live ... blue/neutral and the yellow/green as the return live.

Then you get the twin specialists red/live ... black /neutral and bare earth sleeved with a red or colour sleeve ... In fact recently I called out an inspector who had signed off and installation in a fast food outlet ... the earth wire was used as the return to the lights ... he seemed to feel he had done nothing wrong ... thats wher ethe fight started ... the wire was a twin 2.5 mm connected to a 16 amp breaker ... so he felt that the reduced wire sized was protected from overload ... but I pointed out the the earth only had one layer of protection.

not keeping up to date with the regs for so long ... maybe things have changed and you can now use the earth as a return ... nothing surprises me anymore.


6.3.3.2 The means of identification for an a.c. circuit may be by colours or by
numbers, as follows:
a) where colours are used
1) a neutral conductor shall be identified by black only,
2) an earth continuity conductor shall be identified by the bi-colour
green/yellow only, or by being bare. Green/yellow insulated conductors
shall NOT be used as live conductors under any circumstances,
