    Academic questions regarding rcds.

    I've just introduced myself and have two questions regarding rcds. I understand these monitor "ingoing and outgoing" power and if there is a sufficient imbalance the system assumes there is loss to earth and trips the circuit for safety. My questions are:- 1. Is there a natural leakage to...

    Rcds as main switch

    Fuse board with say 80A rcd main switch on a tt system . I seen guy at work at wrote on sheet as non compliant as rcd main switch should be before fuse board to protect tails. Is is he correct , i would say say no as there's still going to be gap if even if he put in rcd before board

    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,

    Who makes a TP+N panel, bigger than a consumer unit, for example, 14-way (with space for 12 or 14 three-phase breakers). It should feed its outgoing breakers using bus bars, not wires. (I call this a Type B panel) And it should be usable for Dual RCDs, one for the left side of the panel and one...

    RCDs and IR testing...

    Good morning to all. I believe that, this as being a general question, would be best suited in this section of the forum. RCDs are meant to trip (30mA) in case of an imbalance of current (I) between the live and neutral. So, an insulation test will confirm that; 1 - Live to Neutral =...
