I just finished writing up a four page report on a thermal store I was called out to on Friday. The lower immersion heater was rigged up to a timer as there was no available white meter (economy 7 ect).
The timer is a Nobo 500, which is transmited to via RF from the consumer unit. I opened it up to check it after finding many other electrical problems and discovered the cables had melted insulation inside. I mean there was litterly none left.
Phoned manufacturer and confirmed my suspicions. The switch is designed to cope with a 2KW load and not 3.
This is on a rather swanky apartment block in London built 6 years ago, and they're all apparently wired up the same.
What a can of worms.
So look out for this chaps. There where other electrical problems in the property. Continuety between neutral and earth even when the double pole switch was off. Failed thermal cut out on one of the immersions and failure of the sensor pockets with water ingress. All in all, glad its not my place.
