rcd touch voltages

hi could you give me some advice regarding calculations for RCD touch voltages 30mA RCD RA X I^n = < 50v 166 x 0.3 = <50v 100mA RCD RA x I^n = <50000v 500 X 100 = <50000v 300mA RCD RA X I^n = < 50100v 167 x 300 = <50100v 500 mA RCD RA X I^n = <50000v 100 x 500 <50000v any help on this...
