Grounding is a mechanism to protect distribution equipment and people under normal operating conditions, abnormal operational (overcurrent and overvoltage) responses, and hazardous conditions such as shocks. Grounding is necessary to assure correct operation of electrical devices, to assure safety. Power from factory ground must be installed by a qualified electrician. Each DISTRIBUTION BOX and controller must be grounded. This position is the connection point of the grounding wire in the. The first letter T of TT grounding power supply system indicates that the neutral point of the power system is directly grounded, and the second t indicates that the metal conductive part exposed by the load equipment is not connected with the live body, but directly connected with the ground. The neutral grounding method is one of the most important elements to consider when utilities plan and operate their distribution system. During fault conditions, low impedance results in high fault current flow, causing overcurrent protective.
