The switch mode power supply in a computer will leak up to 3.5mA to earth. A Hager 30mA RCD will not trip at 15mA but will trip at a point above 15mA and below 30mA. We would suggest no more than 4 computers on the one RCD circuit in order to ensure that unwanted tripping of the RCD does not occur.
