 |  Re: r.c.d. tripping times ?? the operating current of the rcd is irrelevant for the 1xtest, it should still trip in <200/300mS whatever the rating. all you need to alter is the test current on your test equipment. i.e. 10/30/100/300/500/1000mA. |

| Re: r.c.d. tripping times ?? Rcd test for a 30ma trip Is 1/2 15ma current should not trip 1x 30ma current should trip before 200milli secs 5x 150ma current should before 40milli secs That is for 16th edition So for 100ma rcd you still use 1/2 x 1x 5x |
