[QUOTE="Evans Electric, post: 33347, member: 1408"] I still do not understand why it has to be X5 . Where does X5 come from , why not X3 or X8 . If an RCD trips at ,say 29mA ,30mA or 31mA leakage to earth is there a danger that it may not trip at all at a greater leakage current or the coils cannot handle a greater current . And if it did not trip at 150mA or didn't do it in 40ms what would be the reason ? Deke [/QUOTE]
