Safe use of electricity in the home.

When originally installed a wiring system is suitably designed for its intended purpose and each circuit is safeguarded against the effects of overload, short-circuits and fault currents by protective devices of the correct current rating and breaking capacity.  In this regard, the wiring regulations are explicit that every circuit shall be so designed that a small overload of long duration is unlikely to occur.

However, even in well designed installations circuit faults do develop, the causes of which are not always immediately apparent.  However, quite often the fault is brought about by deliberate misuse of the circuit, or by tampering with the protective device in order to connect a larger load than design specification permits.  This practice is extremely dangerous and can lead to a conflagration and/or death by the inhalation of toxic fumes. Each year a number of fatal accidents occur due to the use of electricity, and many more are badly injured. To keep you and your loved ones healthy and safe, here are some precautions to follow around electricity:

A repeatedly blowing fuse or tripping MCB is a sign that there is something wrong with that particular circuit.  Such a fault should be isolated until a qualified electrician takes remedial action.

  • Never bridge-out MCB’s or 13A fuses by using silver paper or tin foil, it is extremely dangerous.  All such devices are there for protection of the wiring, your property and ultimately yourself.
  • Never ignore the warning signs.  If a plug-top feels excessively hot or if the socket-outlet is discoloured then the appliance being used is too large an electrical load or there are loose connections.
  • Never take portable electrical equipment into a bathroom.
  • Never cover flexible cables and cords under carpets.  The conductor temperature does not dissipate as it should, overheating occurs and a conflagration can result.
  • Keep flexible cables and cords as short as possible and well maintained.  Do not use taped joints rather buy a new lead as this could save money in the long run.
  • Where the flex enters the plug-top ensure that the sheath is properly and securely clamped, inner cores should not be showing, and ensure that the right coloured core terminates in its correct terminal i.e.

    • Brown-‘L’ (LIVE)
    • Blue-‘N’ (NEUTRAL)
    • Green/Yellow-‘E’ (EARTH)
  • It is recommended to purchase appliances that bear a standard mark or number that has been approved by the Standards Association of Zimbabwe (SAZ).  Have foreign standards verified by SAZ.
  • Unless double insulated all appliances will need to be effectively connected to earth either permanently or by a flexible cord/cable.  If you are not sure that this is the case, consult a competent Electrician. The earthing system at your premises is of paramount importance and to ensure that it remains completely reliable it should be inspected by you at regular intervals particularly if a plumbing repair job has been carried out.  All pipe-work and exposed metal work should be bonded to the installation’s earth electrode. A maximum earth resistance of ohms is recommended.
  • A socket-outlet(s) installed for use with outdoor appliances such as a lawn mower should be electrically supplied by a 30milli Amp (0.03 Ampere) sensitive earth leakage protective device.
  • Never leave young children unsupervised in a room containing an appliance that is energized.  Natural curiosity leads them to playing with such items and possibly inserting spoons, forks, etc into accessible openings.  So switch off and unplug or supervise the child.
  • Never fill or top-up an electric kettle while it is plugged in.
  • Never fill a steam iron while it is plugged in (besides which only distilled water should be used).
  • Ensure that the element of your appliance is completely immersed in the water.
  • Never leave an energised iron lying flat on its face.
  • Never leave an appliance switched on and un-attended for any prolonged length of time, accidents do happen and a fire can result.  This applies to every household appliance.  It is only the time scale that differs.
  • Do not wipe appliances down with a damp cloth; electrical components and water are not compatible.
  • Do not wipe or clean electrical switches or socket outlets with a damp cloth, you could be electrocuted.
  • Replace all broken switches or switch covers.
  • Never replace a lamp (globe) while switched on.
  • To lessen the risk of fires and electrocution, Always get the wiring of your house checked periodically, e.g. after every five years.

To reduce the risk of electrocution, always treat all ZESA cables as LIVE, especially during load shedding as power can be restored without warning. All dangling wires should be avoided and reported to the nearest ZESA Fault Centre as they can pose a serious hazard to both humans and livestock.

POWER SUPPLY UPDATE

 

ZESA Holdings would like to advise its valued customers countrywide of the reduction in generation at Kariba Power Station due to depleted dam water levels, commencing on Tuesday 1st September 2015 at 1800hrs, in compliance with the Zambezi River Authority (ZRA) requirement to scale down on water consumption.

 

Generation will consequently be reduced from the normal 750MW to 475MW until dam levels have risen to the requisite levels.

 

During this period, the Zimbabwe Power Company (ZPC) will take full advantage of the reduction of Units in service at Kariba to undertake the annual statutory maintenance, scheduled to be conducted between the 1st of September 2015 and 28 January 2016.

 

Whilst generation at thermal power stations is not affected by hydrological issues, Units at Hwange Power Station will also undergo statutory maintenance which will be completed by 7 October 2015, to ensure greater safety and reliability going forward.

 

The power utility further advises customers that the planned annual maintenance of Hwange and the reduction in water levels at Kariba dam will lead to changes being effected to the previously publicized load shedding schedule.

 

Consumers will experience suppressed power supplies until generation is brought back to normal levels.

 

Although the effects of load shedding will be minimized with possible power imports where available, ZESA Holdings urges consumers to use the available power very sparingly to minimize the extent and duration of load shedding.

 

ZESA Holdings sincerely apologises for the unavoidable inconvenience caused.
