Hi,
My heated towel rail is tripping the main RCD. I'm trying to determine if its the electrical element at fault or something wrong with the wiring. I have disconnected the the Live and Neutral supply to the element and the resistance between earth and Live is approx. 0.5meg ohm, the resistance between neutral and earth starts off at about 0.3Mohms but then drops to 20K. I suspect this proves the element is at fault but want some professional advice before totally remoning it from the radiator only to find its a wiring problem somewhere else.
