[QUOTE="joddle, post: 919200, member: 247983"] Yes questions answered - but still trying to make sense of your problem! And I sympathise with your frustration. First I would a) measure the voltage between the earths in the property - if there is a significant difference then earthing could be the root of the problem. Two other things then I would try to see how good the mains supply is . b) measure the voltage across the lives from each property c) measure the voltage across the neutrals Assuming on the same phase, then if there are any significant differences then perhaps that may explain differentials between the properties. If there are very high differences then maybe phase is the key here. I think your observation about low currents affecting the heart may not be quite so relevent here as it takes a voltage to generate a current to breakdown a component and insulation breakdown or compenent breakdown is usually caused by exceeding a design voltage parameter. My final measurement would be across the centre feeds to the LNB from a receiver in each of the properties to see if there is any PD between the that generated by the kit in each house arriving at the LNB. In theory they should be very similar if not exactly the same. Maybe you have other ideas and after all you are there and can see the situation whereas I cannot - but something is causing the thing to blow and the cause must be coming from somewhere!!! [/QUOTE]
