This means one of the circuit conductors (called the grounded conductor in the code) is connected to ground at the service. For homes, this conductor is the neutral, but in some 3-phase systems without a neutral, one of the phase conductors is grounded. The other circuit conductors are ungrounded. This solid conductor to ground is why you can get a shock between the hot conductor and the earth, water, etc. There are countries that do not do this because they feel it is unsafe. However, this grounding of the system keeps the voltages stable.
