It was the big Switch On of the Christmas Lights on Friday at 6 PM. The lights had been installed a week before and tested all OK.
At 4:30 PM Friday the remote system switching system was installed and tested.
One power feed was found to be dead, This one is fed from an RCD in a street lamp post.
The RCD in the lamp post was showing a few MegΩ between IN and OUT on both Live and Neutral when in the ON position. Obviously both switch contacts inside the RCD had failed.
An emergency repair to replace the RCD had power restored by 5:45 PM.
This morning the failed RCD is showing complete open circuit ( more than 500 MegΩ )
This was sabotage..... by ants who had invaded the RCD
Some had been crushed between the switch contacts.
