[QUOTE="Sidewinder, post: 250519, member: 9512"] You can't use over 250V. If the SPD is at the origin, is the N still connected to the supply? i.e. single pole isolated? If so then on a TN system you will get almost a dead short N-E It won't say much in GN3 as the "new green" GN3 is not yet out. [/QUOTE]
