I was called out last night on a job. The lady told me on the phone that all the sockets had blown in her flat (obvious drama Queen) On arriving and checking the CU, split load half on RCD, which had tripped. Switching all the MCBs off protected by the RCD, Switched back on, hey presto all socets back on, two minutes work. The problem was the shower circuit. She was trying to switch that switchy like thing (RCD) back on and it just wouldn't she said. On further investigation the 45amp pull switch in the bathroom which was wet inside on unscrewing, removed it and tried MCB again. Fine. Checked insulation resistance on cables >299. It had been raining heavily the day before, have you had any leaks I asked. No she replied. but there was a puddle of water in the corner of the bathroom. I have no idea where it came from...... It came through your roof and through your 45 amp shower pull switch. Thats where the water came from. See you Monday with a new switch. I'm sure there are some wonderfull female sparkys in the country, but a majority of women should stick with cooking and ironing....LOLOL
