Is it harmful to use control cables as the power cables for electric motors?
Thread Content
There is a testing device that operates continuously for three to five days during tests, but it is generally not used. The 6 motors in the testing apparatus have a power of 1.5 kW. Control cables of type kVV-4*15, which were taken from other items already available in the warehouse, are being used. Can these control cables be used as power cables instead? What are the potential hazards of using control cables as power cables?
The current-carrying capacity is sufficient as well; when the current is low, there is little induced voltage. It has been used in practice, and it’s hard to imagine any harm that could occur during normal operation. Perhaps there are multiple wire cores, and there’s a risk of incorrect wiring, which could result in the spare wires becoming energized. When the motor loses a phase, induced voltage appears on these spare wires, so it’s best to short-circuit them to ground. Also, it is 4*1.5, not 4*15
