QUOTE(ceo684 @ Mar 4 2021, 12:40 AM) Why buy 2 piece of mains RCD 100mA and 30mA when the requirement is "maximum of 100mA tolerance" - i.e. NOT "equal to 100mA" or "not less than 100mA tolerance"? Yes is correctA single 30mA for whole house is cheaper TCO and provide better life protection whilst still fully compliant to the regulation of "maximum of 100mA tolerance".  In practice is better to use 3 units of 30ma single phase So when trip won't bring down the whole house power. It's not only about compliance but rather safety and convinience Ts if have money pls add spd too |
