Equipment Grounding Conductor
The equipment grounding conductor or cable is connected to ground at
the service equipment.
It should be installed as part of the circuit supplying the system and
should not be smaller in size than the ungrounded branch-circuit supply
conductors.
A bare, covered or insulated grounding conductor is acceptable. An
individually covered or insulated conductor should have a continuous
green, or green with one or more yellow stripes, outer Þnish.
The attachment-plug receptacle in the vicinity of the system should be
of a grounding type and the grounding conductor serving the receptacle
should be connected to earth ground at the service equipment.
