)Its a bit late (more than 20 years ago) ... that 2 year old child electrocuted to death by a stove wire left exposed on the kitchen floor ... I doubt the person who left the wires like that even knows his actions caused the death of a 2 year child ... he sold and left the country.

What 6.16.3.3.3 means is that if you disconnect a stove by means of a flexible arrangement ... you have to remove the wires and make it safe.

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.Comments are based on opinion...not always facts....that's why people use an alias.Comment

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?

I couldn't get the preview to work on my phone but I now have it on my computer. I see that # 2 is extra regs for generator installations.

Further reading. I now understand that SANS 10142-1-2:2021 refers to installations where the generator is connected directly to the grid network. This apparently does not include generators that are connected to an electrical installation via a 3 way switch.

Just been having the discussion on what is covered by what. I originally thought a contradiction, but it has been pointed out that SANS10142-1 excludes alternative supply operating in parallel with the main supply to an installation.( 7.12.1.1 note 2 )
Sans 10142-1-2 is for systems running in parallel , typical gridtie systems or running generators in sync with supplyComment

I have purchased Ed 3.01. (Pdf)
I have come straight from Ed 2 (2017).
So far I am not seeing the massive changes that was expected.
I don't have the table of changes that would have been stated in ed 3.0

If anything the regs are more relaxed ... so you might get into trouble for telling a customer they cant use cabtyre to wire their entire house ... or get confused about whether or not you have to install a double pole isolator for a ceiling fan or just put everything on earth leakage ... really dangerous stuff.Comments are based on opinion...not always facts....that's why people use an alias.Comment

I think expectations of the industry are high ... a lot beer talk at the meetings ... but in reality the people who did everything by the book because it was the right thing to do ... is a thing of the past ... now it has just become a free for all ...he who comes up with hte smartest way to dodge the regs wins ... using the twin+E looking speaker wire ... you have to give the lad or lady credit ... if it looks like twin and feels like twin it must be the right wire for wiring plugs
... just because a label says speaker wire.
What are the implications of using speaker wire ... simple load carrying capacity ... connect a cellphone charger and you would be good to go ... connect a 2 plate stove and you going to light up your life

Good rising.
Busy planning a job for tomorrow. Surface job in a larny complex. Newly built garage.
Was planning to use conduit and camera boxes for connections and terminations as normal, but client doesn't want conduit.
Insists on trunking.
Quick question. I have checked SANS , but I need a bit of confirmation. Are terminations and connections on FTE allowed to be made in trunking ?
Peace out .. DerekComment

Morning!
Good question...
I would say yes if easily accessible and maybe a note saying where it is.
I have often seen cables extended inside a 100x40 trunking. Even in UK.
What did SANS say ?
Only question I guess is what manufacturer says as that may be the ultimate say.
SANS may not know but the manufacturer should.

A question that has no straight black and white answer but I would say not unless you use a cable coupler
We avoid joints in trunking purely due to fault finding afterwards and most of our specs from the consultants do not allow it.
Saying that we have had to join on long runs and have used the proper IP rated " connector " ,which has the glands on either side, to prevent strain and also in case somebody is busy with his fingers in the trunking tracing a circuit.
5.2.1 no touching without opening with the use of a tool
6.3.7 - joints accessible ( trunking , yes if you can find It) , protected against strain ( going to be difficult unless you use a coupler )
6.5.1.1 k - also refers to joints not accessible even when covers are open.
Have pasted what I perceive to be relevant regs below
6.3.7 Joints and terminations
6.3.7.1 Joints and terminations of cables, cores and conductors shall be
made in accordance with manufacturers' instructions or the appropriate part
of SANS 10198.
Flexible cables shall only be joined using termination boxes, cable couplers or
manufacturers’ jointing kits.
All joints shall be accessible, protected against strain, and protected in
accordance with 5.2.1, except for joints made and sealed permanently and
intended to be maintenance free.
6.3.7.2 Joints and terminations shall not
a) adversely affect the current-carrying capacity, the insulation resist-ance or
the earth continuity of the cable, core or conductor in which they are made,
b) be made in any connector, bend, elbow or tee-piece of a conduit,
c) allow the strands of a stranded conductor to spread, or
d) require strands of a stranded conductor to be cut away to allow connection
of the conductors (for example, to terminals).
5.2.1 Live parts
It shall not be possible to touch any live part within arm's reach with the
standard test finger (see SANS 60529)
a) during normal operation, or
b) when a cover is removed, unless the cover is removed with the use of a
tool or a key.
6.5 Wireways
6.5.1 General
6.5.1.1 When a wireway is installed
k) where it is accessible to the public, protection shall be such that it is not
possible to touch any live parts with either the standard jointed test finger
or the 2,5 mm diameter 100 mm long rod (see SANS 60529). This
protection also applies after opening any door or cover that can be opened
without the use of a tool or key; and

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,Comments are based on opinion...not always facts....that's why people use an alias.Comment

With regards to joints in trunking ... I recalled being called out for condemning a project which had joints in every part of the trunking ... it was pointed out to me that if only a percentage of the trunking is used as a wireway .. IE 25 % full ... joints were allowed in the trunking ... that where the fight started ... you couldnt fit the cover on the trunking it was so full ... his argument was that when he did the joints the trunking was half empty.Last edited by ians; 15-Dec-21, 12:37 PM.Comments are based on opinion...not always facts....that's why people use an alias.Comment
