    RCD trip times (Table 3A)

    I'm trying to find a list of trip times for 30/100/300/500ma rcd devices to make some flash cards. I've found table 3A but it's somewhat confusing. If I read it correct, the table suggests a 30ma rcd should trip at 10ma. I must be reading it wrong? Anyone know how to read the table correctly...

    Tripping times for a 100mA RCD?

    Could anyone confirm if we test 100mA RCD's at x5? There is a lot of information on the web that says you only test at x1 but Table 3a in appendix 3 clearly shows a max disconnection time for a 100mA RCD at x5 to be 40ms. Thanks all.

    I'm confused about Type C Breaker Disconnection Times

    Hi All, When I consult Table 41.3 for a Type C Breaker rated 16A I see s max Zs of 1.37 Ohms. However this value is defined for both a 0.4s AND 5s disconnection time. This is obviously correct so I am missing something. Fig 3A5 also shows the table 0.1s to 5s. Can anyone explain please...

    RCD testing times BYB vs OSG

    Happy new year folks; just been looking at trip times as i need a photocopy for a client. Anyhow, in the OSG (page 112) for a general RCD, it states "with a leakage current of 100% the device should open in less than 200ms". However in the BYB (Table 3A, page 318) the table says device should...

    Why are the RCD trip times for I and 5I 300ms and 40ms

    Is there any particular reason why the trip times for RCDs at I and 5I are the values they are (300ms and 40ms). Is there some particular medical reason why?? I'm just curious, no particular reason but may weave that into the conversation next time I'm in the pub!!

    Hello. Just a quick query please lads. Operating times for RCDs, (non-delay) on 100% of rated residual tripping current. Is the maximum operating time 300 or 200ms? Guidance Note 3 states 300ms, but various other publications say 200ms. I was under the impression it was 200ms. Just trying to...
