Every now and then we hear about creative alternative ways to arrange an earth connection if the wall socket does not provide one. There is especially onewe would like to highlight as particularly hazardous and we hope this statement does not serve as yet another creative way. Occasionally the water heat radiators have been connected to the hi-fi gear cabinets or to a mains distributionblock earth contact plate. This works normally from the electrical point of view.Until the following happens; one of the devices become faulty and the cabinet becomes energized with wall socket mains voltage. The water radiator system maynot be properly grounded to earth potential. Now, this means that there might not be a large enough fault current through the water pipes to blow the fuse, thus disconnecting the fualty device. Further it means that most of the pipings and radiators are energized with wall socket mains voltage. If this is in an apartment house, every neighbour tenant has potentially lethal voltage in their radiators. It will not show. Until e.g.small children touches the radiator. We

strongly discourages

from the above or any other way to arrange a ground connection other than according to the local laws and regulations for electrical safety.
