    Also, on a normal TN split load board . The 30mA rcd is also providing protection against indirect contact (along with supplementary protection against direct)
    Who would argue that it is not admissible to fill in all your Zs boxes with 50/30mA =1666 Ohms after all despite the type/size of mcb s fitted 1666 Ohms is the max Zs permitted value ?
