Examples include cranes, pumps, fans, sand sifters, compactors and masonry saws, to name but a few. According to device standards, Type A residual current circuit-breakers must not be subjected to smooth DC residual currents higher than 6 mA. The reason for this is that even low smooth DC residual currents can have a detrimental effect on any Type A or Type F circuit-breakers, with the result that...
