My in-laws have a problem where the TCD on the distribution board trips occasionally when the electric shower is on. They have had the shower replaced and the new one also does the same thing. I assume this discounts the shower as the problem. I have asked them to disconnect all appliances and try again and again it sometimes is OK and sometimes trips. Any idea how I can investigate further? I come from a computing hardware background so have basic electrical skills and have a good multimeter!
