Electrical Safety After a Flood

Your Safety

Our team at Napier Electric Co. wants to ensure you are safe and take precautionary steps around homes or electrical systems that have been flooded or potentially flooded. 

When in survival mode, it is easy to overlook some of the basics that need to be considered. Here are some thoughts before entering or conducting work around the property.


It is important to note that power is still being reinstated and sometimes intermittent; you should always treat electrical systems as though they are live and working. Also, mud deposits, silt, and debris can conduct electricity, making premises and part of the surrounding area highly dangerous.


The Property

It would be best if you were extremely careful when re-entering an area to begin the clean-up. If your power was not turned off before the flood, wait to enter your home or business until it can be verified that it is safe; get on the phone with Napier Electric to talk further.

Note: If your property or connecting line has been damaged by a storm or flood, you may need verification tests on your switchboard, main earth, wiring, equipment, and appliances to be carried out prior to reconnection to ensure the electrical circuits are still working.

If you see any obvious signs, such as electrical arcing, a burning smell, smouldering or 'on fire' electrical appliances, and submerged socket outlets, these are all signs that you are not safe. If you can safely do so, turn off the main switch which will be located in the switchboard or meter box. If you can not turn off the power safely, remove yourself from the property and call Napier Electric. (Note: If fire is imminent, call 111).

If you did turn your power off before the flood, don't try to turn it back on yourself. Have your property checked by an electrician.

Your Appliances

Any appliances that have become wet should only be plugged back in once they can be checked by an appliance repair technician or electrician and found safe. A small amount of moisture trapped inside an appliance can cause significant damage or electric shock.

Electric Vehicles & Solar

- Do not attempt to charge electric vehicles if the vehicle, the charger or the lead has had water damage.

- If your solar system has been damaged, get a licensed electrician to inspect it, make any repairs and check it's electrically safe before it is re-commissioned. (Note: With the power being reinstated, it may cause arching, turn off power at your mains, and call us straight away).

Notable Thoughts

- Please do not use any mains-powered electrical appliances in areas affected by flooding until advised by a registered electrician that it is safe to do so.

- Seek professional advice about restoring your property and seek advice from master electricians to undertake any repair work.

- Get in touch with your local lines/network provider if you see any exposed underground cabling or any potential danger that could be caused by damage to overhead lines. (At the moment network providers are under huge pressure, if you can not get a hold of them please call your electrician before before commencing any type of work).

- Lastly don't do your own electrical work, it's illegal and dangerous. Always use a licensed electrician.
