SANS 10142-1:2017 (Ed. 2.00)

[ians]

Imagine that another another family leaving for a safer place to live. Bonus for me, i get to inherit the latest Sans edition 2 with a pile of seminar documentation. I might get around to reading the drivel printed, one day when i retire.

Working on site at the moment, wonder why people waste all this time and money on rules and regulations, safety induction, medical checks ...blah blah blah. Then you open the roof tile and look across the ceiling and wonder why the safety of all the employees working in the office is not taken into consideration.

Finding shyte like, white wires being used as live...neutral and in some cases earth. No earthing on the plugs sockets, no earth leakage on any white sockets, the list is too long.

I can tell you why, because it is paper work to cover the companies a$$ in case of an accident. Companies can be lucky i am not a government safety consultant with authority to shut down buildings due to negligence. I do have the authority as a master electrician, however i have bills to pay like everyone else. It was bad enough having inspectors come to site to collect their case of the finest whiskey back in the day, but now there is absolutely no control.


My aircon mate arrived yesterday, telling me a how he was electrocuted and burnt on a site due to incorrect labeling and unsafe working conditions. A couple contractors die, what is the big deal?

Afternoon all

When it comes to stove connections the regulations refer to stove being fixed appliances which is normal.

The issue I have is that further on in the regulations it stipulates that freestanding stoves, a stove coupler must be used and if not must be on an earth leakage.

What about non freestanding stoves?

I place all stoves on an earth leakage and was questioned and asked to show were in the regulations non freestanding stoves must be on an earth leakage and I can't find it.

Hi

I think the reason they state that a stove on a stove coupler need not be protected by ELU is to cut out any confusion with regards to socket outlets that need to be on ELU.They are ensuring that everybody understands that a stove coupler definitely does not need ELU
If you look at 6.16.3 it defines a built in unit as a cooking appliance under fixed appliances.
Under 6.16.3.2.3 it states that it only requires ELU if the cooking appliance also feeds a standard socket outlet.( this was for the old isolator that used to come with a socket outlet for the extract fan) I think from 6.16.3.2.3 it is clear as mud that you don't need ELU protection on a cooking circuit under normal conditions

6.7.5.5 The following do not need earth leakage protection:
a) socket-outlets connected to a safety supply, but see 7.8.3.3 and 7.12;
b) a socket-outlet that complies with SANS 164-4 and that is intended only
for the connection of an appliance for critical application (such as
emergency lighting, a deep-freeze, a burglar alarm, data processing
equipment, or life-supporting equipment);
c) circuits that supply fixed socket-outlets positioned out of normal reach,
rated at less than 16 A and intended for the connection of luminaires (see
6.14.1.4); and
d) a stove coupler that complies with SANS 60309-1 and of dimensions as
given in SANS 337 (see 6.15.1.1.5).

6.15.1.1.5 A stove coupler shall comply with the requirements of
SANS 60309-1 and shall be of dimensions as given in SANS 337.
NOTE 1 Earth leakage protection is not required for the stove circuit when a stove
coupler is used.
NOTE 2 For a three-phase coupler, the earth connection needs special consideration.

6.16 Fixed appliances
6.16.1 General
NOTE The general requirements in 6.16.1.1 to 6.16.1.12 apply, except where
otherwise required for specific cases.
6.16.1.1 Fixed appliances do not form part of the electrical installation other
than their positioning in relation to the supply and the wiring carried out
between different parts of the appliances

6.16.3 Cooking appliances
NOTE Cooking appliances include built-in stoves, oven hobs, and the like (see also
6.16.1).

6.16.3.2.3 A cooking appliance circuit may also supply one socket-outlet if
the rating of the socket-outlet does not exceed 16 A and if the following are
all contained in one control unit (see also 6.15.4.1):
a) the socket-outlet;
b) an earth leakage protection device including overcurrent protection for
protecting the socket-outlet; and
c) the switch-disconnector required for the cooking appliance (see 6.16.1).
NOTE The socket-outlet has to be protected against earth leakage so, unless the
protection device (see (b) above) is in the control unit, the entire cooking appliance
circuit has to be protected against earth leakage.
