I've got about 100volts running through the earth from somewhere localised to one corner of my kitched. If i touch the kettle with a wet hand, or a cut finger, i get a bit of a shock - nothing major, but bloody annoying. any clues on how to trace it. it happens with barefeet touching a nail that holds the wooden floor to the concrete subfloor. the diswasher and kettle are not in the same socket. Noticed sunday an earthing lead hanging loose beneath the kitchen cupboards. A very mild current running through the cold water tap also not uncommon. Dishwarsher plug is beneath the sink, the kettle socket about 2 foot from the sink. any clues on how to trace / remidy this would be great. many thanks.
