Ungrounded system
An ungrounded conductor in an ungrounded system will only have a voltage relative to the other ungrounded conductors in the system, but will not have a voltage relative to ground. For a ground fault to pass current and trip a overcurrent protection devices or a residual current device, two seperate ground faults will be required. This means that a person could touch the busbar of either conductor independently at be safe as long as there is no fault.
