3 phase Residual current devices.
Can someone explain how an unbalanced 3phase supply can affect the operation of an 3ph RCD when the system has its own earth leakage caused by computer equipment

RE: 3 phase Residual current devices.
However you talk about earth leakage through computer equipment - this is different and has no relation to the unbalanced LOAD but is a current UNBALANCE. Thus you need to be specific with this one.
An RCD tends to trip only if you have an UNBALANCED current not an UNBALANCED load.
