I've just fitted a new light into an existing circuit - I did some coninuity testing to make sure I had good connections and earth connectivity, and discovered that I also have some continuity between earth and neutral. What I'm actually finding with my =A39.99 from B&Q tester is that on earth I have full continuity and a good strong buzz, but between earth and neutral I have a broken but regular buzz, almost as if its oscillating if that makes any sense. What I also notice is that if I turn off the mains switchh on the consumer unit, as opposed to just the MCB on the circuit I'm working on, the continuity disappears. I'm not an expert and don't want to get into dangerous areas beyond my knowledge - can someon advise if this is normal or if I have a problem I should be concerned about. I read somewhere else that there is usually a connection between earth and neutral in a modern consumer unit. That doesn't make sense to me intuitively, it sounds dangerous, but then I'm not an electrical engineer. Any advice gratefully received.
