    Issued a coc then just for the Db , socket and security lights

    The catch with doing this, make sure the purchaser has not seen the house before you start cutting wiring.

    If there is a light or plug and you have removed or cut the wiring , the seller will be liable to make it work. One of the reasons I always tell my customers to do the COC before they put the property on the market.

    Good morning

    According to the new SANS 10142-1:2017
    6.16.1 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 remains the same
    6.16.1.2 The power supply to every fixed appliance, except luminaires, shall be supplied through
    a) a disconnecting device that disconnects both live conductors in a single phase supply and all phase conductors in a multi phase supply, or
    b)a socket outlet that is directly accessible at all times that any person is exposed to such appliance while the supply is on. In the case of a remotely installed appliance, the position of the disconnecting device shall be indicated by means of a notice in close proximity to or on the appliance.
    6.16.1.3 Where a fan or heater is included in a luminaire, the luminaire is regarded as a fixed appliance. If the luminaire circuit is protected by an earth leakage protection device that has a rated earth leakage tripping current (rated residual current) not exceeding 30mA, a disconnector is not required (see 6.9.3.1).
    6.9.3.1 An appliance or equipment that is not supplied from a socket outlet, including equipment automatically or remote controlled, shall be capable of being disconnected from the supply by an easily accessible switch disconnector. The disconnector shall be mounted (if not specified elsewhere in this part of SANS 10142, but excluding luminaire circuits) (see also 6.16.1.4)
    a) within arm,s reach from the terminals of the appliance, or
    b) in a distribution board, if the device is capable of being locked in the open position.
    The disconnector can control more than one appliance if the functions of the appliances are ralated. Where equipment which belongs to the supplier of electricity (such as meters or remote controlled load switching) is installed, the main switch may be regarded as the disconnecting device.
    6.16.1.4 The disconnecting device shall be positioned
    a) within 1.5m from the appliance, or
    b) in a distribution board (if the switch-disconnector is capable of being locked in the open position).
    Even where a disconnecting device is on the appliance, a separate disconnecting device shall be provided in the fixed installation to allow for the removal of the appliance.

    Hoping that this clears up any confusion between you and your potential client.
