What to do after the power comes back on?
If you have partial power or are without power after the planned outage, then check your meter box to make sure safety switches including RCDs (residual current devices) have not operated.
Make sure your RCDs in your meter box are at the 'on' position.
In certain circumstances equipment (such as air conditioners) may also need to be reset in accordance to the operating instructions. Should the instructions not assist you to reset the device, you would need to seek assistance from the manufacturer or installer for assistance.
