A 12v pond light fitting had been incorrectly connected to a 230v supply. The light fitting corroded causing the water to come into contact with live terminals and the pond to become live. A dog jumped into the pond and was electrocuted. Energy Safety was able to confirm that the installation was correctly installed originally and that a ‘repair’ had been carried out by an unknown person at a later date. This person could not be identified. The owners of the pond took steps to eliminate the possibility of this occurring in similar installations and set up a routine periodic inspection of all other electrical installations.
