12V Downlighters

See SANS 10142 & the OCCUPATIONAL HEALTH AND SAFETY ACT, 1993 ELECTRICAL INSTALLATION REGULATIONS of 6 March 2009:

If an appliance is on a plug (or not) it is excluded from the definition (and such regulations of SANS 10142) of an installation.

On the "TEST REPORT": Point 3: "This report covers the circuits for fixed appliances, but does not cover the actual appliances, for example stoves, geysers, air conditioning and refrigeration plant and lights.

The "geyser" / "waterheater" is ALWAYS excluded from the current SANS 10142 re the CoC:

6.16 Fixed appliances

6.16.1 General

NOTE The general requirements in 6.16.1.1 to 6.16.1.13 apply, except where
otherwise required for specific cases. Amdt 4

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

6.16.2 Water heaters

NOTE Water heaters include geysers, instantaneous water heaters including units
for boiling water, and the like (see also 6.16.1). Amdt 4

6.16.2.1 All water heaters shall be bonded in accordance with 6.13. (read 6.13 .... nothing to do with the geyser itself, the water systems hot and cold must be bonded - no geyser appliance related issues)

6.16.2.2 Dedicated circuits shall be provided for water heaters and there
may be more than one water heater on each circuit. (dedicated circuits to water heaters, no other circuits to be on that circuit...other plugs, lights, jacuzzis, pools, cold rooms etc)

NOTE If a water heater is installed in a bathroom, see table 7.1 regarding earth
leakage protection. (Supply to geyser issues)


"electrical installation" means any machinery, in or on any premises, used for the transmission of electricity from a point of control to a point of consumption anywhere on the premises, including any article forming part of such an electrical installation irrespective of whether or not it is part of the electrical circuit, but excluding
(a) any machinery of the supplier related to the supply of electricity on the premises;
(b) any machinery which transmits electrical energy in communication, control circuits, television or radio circuits;
(e) an electrical installation on a vehicle, vessel, train or aircraft; and
(d) control circuits of 50 V or less between different parts of machinery or system components, forming a unit, that are separately installed and derived from an independent source or an isolating transformer;

"point of consumption" means any point of outlet or the supply terminals of machinery which is not connected to a point of outlet and which converts electrical energy to another form of energy: Provided that in the case of machinery which has been installed for any specific purpose as a complete unit, the point of consumption shall be the supply terminals which have been provided on the unit of machinery for that purpose

"point of outlet" means any termination of an electrical installation which has been provided for connecting any electrical machinery without the use of tools;

(The "electrical installation" ends at the point of outlet (plug) or if not plugged in at the supply terminals of the machinery)

Thank you for your input.
You are quite correct.
The point I was making however, can be shown using the following examples:
1./ Regardless of whether the circuit supplying a gate motor (or any other fixed appliance) emanates from a plug socket outlet or a circuit breaker, the entire circuit supplying the motor is subject to the SANS 10142-1:2009.
2./ I once came across a house where the entire outbuildings supply was re_routed to a socket outlet in the kitchen. A friend of the family told them that it was not part of the electrical installation anymore, and would not be on their certificate. This was incorrect advice.

I think a bit of confusion has arisen. The geyser as an appliance is not covered by the COC. If it is faulty you are not required to repair it before certifying the installation. The geyser MUST however comply with the applicable regulations: correct gauge and protection on the supply, earthing, bonding ... and while on the subject ELCB protection if mounted in the bathroom :-)

My understanding has always been that any circuit under 50V does not require a COC and is excluded from the regulations.
Home alarms, intercoms and Solar systems and battery systems fall under this category. However I would assume that if there is an inverter involved, which generates 220V, may ...........................

The circuit for low voltage lighting (usually 12 volts) is covered extensively in Section 7.9 of Sans 10142-1:2009.

Solar systems are also covered in section 7.12 Alternative supplies (including low-voltage generating sets,
photovoltaic (PV) installations, etc.)

I hope this helps
