Protect your appliances against power surges during load shedding

The effects of load shedding on your household stretches further than just interrupting your power supply. Unfortunately, the electrical network was never designed to have parts of it regularly switched on and off. In doing so it poses a risk of power surges which could damage certain components in your household, especially appliances. 


What is a power surge? 

Power surges in the electrical supply can increase the electrical current flowing to your appliances. This short term spike (literally nanoseconds) in voltage is potentially damaging to electrical and electronic components. 

Although load shedding is the biggest culprit when it comes to power surges at the moment, power surges can also happen during thunderstorms in the nearby vicinity. A lightning strike on your home or a power line will potentially cause a massive voltage spike which will almost always cause damage. The best protection against lightning strikes is to unplug all electronic devices and appliances, even when not in use. 


How to protect your appliances against power surges

There are various power surge protectors on the market. One in particular is a power surge adaptor. These work just like a normal adaptor, only it protects your appliances against power surges too. The manufacturers of these devices also offer a warranty on the products it is to protect. Although the market is supposedly regulated, always make sure the product you buy has the SABS stamp of approval on it.

Another option is power surge protector plugs. To use these, you will have to cut off the existing plug on your appliance and rewire the new surge protector plug.

How to wire a surge protector plug 

  1. Unplug your appliance that will be fitted with a surge protector plug, and cut off the existing plug. 
  2. You will see three wires. Clean the plastic insulation off each wire, about 5mm from the end. 
  3. Twist the copper wire neatly between your fingers and gently fold over the wire. 
  4. Remove the surge protector plug cover. 
  5. Unscrew the little screws on each of the plug’s pins a bit and insert the prepared copper ends in each of the pins. Now tighten the little screw on each of the plug’s pins firmly, but do not overtighten them. 
  6. When putting the pins back in the plug, insert the green or yellow wire into the top pin. 
  7. The blue wire goes into the left pin and the brown wire into the right pin.
  8. Replace the cover of the plug and you are ready to plug the appliance into the wall and switch it on. 


Although this might seem like a lot of work and money spent on a bunch of plugs, it is a good investment to make in the longevity of your household appliances. The reality of the times we live in is that load shedding is here to stay for a while, and it is best to be prepared and protect your appliances from damage.
