[QUOTE="ProDave, post: 263286, member: 6969"] Nope. I've drawn it out, and a N-E short at a light fitting, to me looks like some of the N current will flow via E, and so will cause an imballance and trip the RCD. So I'm watching the thread to see what is magically different about TT to see a drawing of the installation of the circuit, the fault, and the current flow so see how it can disable the RCD. [/QUOTE]
