NICEIC Certification Scheme NICEIC Online Certification Rated Time Delay

Could someone who uses this software tell me what the Rated Time Delay box is for when filling out the Main switch/ Switch-Fuse/ Circuit-breaker/ RCD section of an EIC?

Is it for the recommend range in which a time delayed rcd should trip 130 - 500ms... or is it something else?

Would that not be for S-type RCDs?

yes it is but what is rated time delay, am I correct in putting the required trip time of an 100a 100ma s type rcd main switch in that box....who knows.

I could be a million miles off, but I thought if you have a 100ms time delayed RCD then that's what you would put?

Perhaps not though, have a look at this thread:

there is no such thing as a 100ms time delayed rcd.

rcd's have ln rated current and IdeltaN RCD operating current.

I think I will put 130-500 which is the range within the rcd should operate....

Sorry dude, now I know Think 130-500 is what it says in that other thread I linked to though.
