Control boxes are made of hi tech components and designed to perfection with various features to give ultimate protection to the prime movers such as submersible motors centrifugal pumps etc. Use 25 mm2 awg 14 70 c copper conductors only and tighten all connections to 2 nm. Provision of ammeter and voltmeter to check the voltage current in specific models only. Also it is a good idea to either use an in line fuse or an arp circuit breaker in line with the power supply to the control box. After determining the voltage is zero disconnect the motor wires directly from the pressure switch box m1 and m2. The inbuilt micro controller gives complete protection to both single three phase pumps.
