The power cables of the GBCR are used to connect the PDF to the PDB. This ensures a stable power supply for the GBCR. The PGND cables are used to connect the cabinet to the PDF or to the grounding bar in the equipment room. This protects the cabinet from electrostatic discharge. The connections of power cables in the cabinet vary with the types of power distribution box in use.
