[QUOTE="Phoenix, post: 554929, member: 8133"] As above the generator is probably not earth referenced and the windings floating. Your earth terminal probably only goes to the generator frame. This is fine for running single items (such as a power tool in the middle of a field) and is effectivly an IT system, but is no good for suppling an installation, unless there is monitoring for the first fault and the instalaltion is under the control of a skilled person. Generally you'll have to provide a N-E link at the origin of the installation. Have a look at section 7.1.3 of BS7430. You could put as many earth electroduces in the ground as you want, and still not get an earth loop reading (hint: get a sheet of paper and try and draw out the fault path) [/QUOTE]
