A friend of mine owns several residential properties, which he contracts out to Local Authorites to provide tenants. The LA is 'Supposed' to inspect the properties at regular intervals, as, sad to say, but those who have no financial interest in the property and have their rents paid by the state, sometimes abuse this. Matey is responsible for ongoing maintenance of all the properties, to a safe standard of course, and this is a photograph he sent to me earlier today. This user socket had been correctly installed, . . .but the tenant wanted some additional power in the next room. . .( Notice - No Earth wire. . .) When matey's electrical contractor arrived, there was NO electrical power at all in the building. He soon found that 'Someone' had actually bypassed the main fuse board distribution unit and electricity meter, by feeding a cable around it from the main street supply. The problem with this ( technically - forget the legality for a moment ) was that whoever did it, had used a length of flat 'Twin and Earth' cable capable of handling 240 volts at a maximum continuous current of 20 Amperes, and the tenant found that this cable burned out when he used the electric cooker, with other electrical appliances also energised.. ( Should use a 45 Amp feed just for the cooker alone ) In fact, the whole 3 bedroom house, lighting and all, to service a family of five, was being supplied thru a short cable having 2.5mm cores. This melted, forunately with no fire caused. However, it was found that no electricity supply bill had been paid on that property for nearly seven months ( usually Quarterly billing - the State do not pay the leccy bills) The family had 'No Idea' who had carried out the modification.
