What you will see

  • A manual changeover lever or an automatic transfer switch near the main board.
  • A generator connected somewhere other than a proper changeover.
  • Flickering or tripping when the generator starts or stops.

Why it happens

If a generator or inverter feeds power back into the grid during load-shedding, it can energise a line that a lineman believes is dead. It can also damage your inverter or generator when the grid returns. A correctly wired changeover physically keeps the sources apart.

What you can check yourself

  • Find your changeover and learn which positions mean grid, generator and off.
  • Check that the generator only connects through that changeover.
  • Tell us if an electrician has added or moved anything in the board.

What not to do

  • Do not connect a generator directly into a socket or the distribution board.
  • Do not switch the changeover while heavy loads are running.
  • Do not bypass the changeover to run everything at once.

When to call us

  • You are not sure how your generator connects.
  • The system trips or behaves oddly when the generator starts.
