A customer in Cabinteely tried to change the immersion switch in his own home and blew the main fuse in the house. I had the electricity back on fairly quickly and rewired the immersion switch for him.
Please don't mess about with electricity as it can be quite dangerous.
Another customer in Leixlip changed the shower pull cord switch and luckily they asked me to check it out. There were 3 loose connections which could easily have caused a fire.
