    Time Delayed RCDs

    If anyone has time to explain how time-delayed RCDs function, or point me to an article that explains it I'd be very grateful. I understand the principles behind a standard RCD, just very curious how that same design can then incorporate a time-delay. Many thanks,

    Rcbo

    I should know the answer but I don't and have tried google etc so that's out of the way for starters. Reading a post about sockets used for IT equipment and the possible problems caused by RCD tripping due to start up earth leakage, led to think about protecting the circuit with RCBOs with a...
