@Morphix . You make some very good points . If it is grey area it may be left to members disgression . If you are the worrying kind , arrange to take it to your local appliance man and have it tested . Peace of mind for a fiver or so . When I was an appliance engineer , I used to PAT test everything after repair as a matter of course .I still have my PAT tester , but I will not pay £100 to have it recalibrated to just test one charger ,I will phone one of my mates in the trade . Basically , for purposes of PAT testing there are two types of appliance , those with metal cases or exposed metalwork , which must have a 3 wire mains lead[including earth] and the plastic case variety which are called "double insulated " and have no earth , just a 2 wire mains lead . If your charger has a metal case , make sure that all 3 wires are connected within the plug , unless it is a sealed plug in which case you cannot check . A check you should do , irrespective of the type of plug , is to use a multimeter to check that there is a very low resistance connection between the earth pin on the plug , and the metal case of the charger . All we really need here is a very large dose of common sense . Almost all premises are protected by earth circuit breakers these days , so the risks are very small .
@Muckymitts . It is true what you say about paying £50 for the right bit of paper . I am actually surprised that insurance companies dont insist that all the appliances in our homes are PAT tested . Incidentally , it is my understanding that PAT testing applies only to portable appliances , which means anything fitted with a mains plug .So it does NOT apply to electric cookers or indeed BATTERIES . Then there is this "competent person " thing . I ran my own business for 20 years as an appliance engineer . I was self taught , and was informed that there are no recognised qualifications apart from City and Guilds , which are voluntary . My mate who was a self taught mechanic worked for the local crane company . He was very good at what he did , and indeed used to test similar machines for the local council , in his capacity as a "competent person " I think that the legal definition of a "Competent Person " is someone to blame when the excrement hits the fan . . Long live common sense .
