    VOV generators

    I know this topic has been dealt with on numerous occasions but feel we need to make all aware of the regulations & dangers of connecting a VOV generator to an existing fixed electrical installation.

    As load shedding is again part of our daily lives, people are reverting to generators for backup power.
    Please be advised that most portable generators sold in SA are VOV wound and may not be connected to a fixed electrical installation.

    SANS 10142-1 states in clause 7.12.2.7 that a 230 V generator with a V-O-V earth connection (centre tap on winding which is earthed) shall
    not be connected to a fixed electrical installation. Such a generator may only be used as a free-standing unit to provide power to specific appliances

    That been said, there are many companys connecting them with a change over switch to fixed installations.
    Should an incident occur, all involved parties will be investigated and the homeowner could attract liability if
    the installation is not safe or is not correctly used.
    It could also invalidate the insurance on the property.

    Note: Remember that any alternate power installation must be executed by a person registered with the DoL.
    The registered person must issue a CoC upon completion of the electrical installation.
