Grounded system

An ungrounded conductor in a grounded system will have a voltage relative to the grounded conductor and the ground. For a #Ground fault to pass current and trip a overcurrent protection devices or a residual current device, only one ground fault is required: between the ungrounded conductor and the ground. This means in this system that a person could touch the busbar of either the grounded conductor or ground and be safe as long as there is no fault, but not the ungrounded conductor.
