Can a SPD be installed in a domestic installation without an earth conductor connecting it to the MET, because it will discharge the surge from the live line conductor to the neutral conductor?
I watched the video last night and have been considering the lack of an earth conductor.
I thought an earth connection is required to discharge the surge and it is part of the less than 300 mm live earth loop that is required, that can be stretched to 500 mm, but not omitted altogether. Either way not connecting the SPD earth terminal to the MET seems a bit lack.
