Is the power supply circuit for the fire pump a 4-core cable? Who’s on site to take a look? Help is needed

To connect the cable from the distribution cabinet to the water pump control cabinet, only a 3+1 cable is needed. Since the water pump operates at 380V and does not require a neutral wire, three wires are used to connect the three phase conductors, while the fourth wire serves as the ground for the casing of the water pump motor
