Working voltage of medium grade cables is-
650 V
The working voltage, also known as the operating voltage or rated voltage, is the voltage at which the cable is intended to be used continuously. Therefore, selecting cables with the correct voltage grade is paramount for the safety, reliability, and longevity of electrical systems. Therefore, the correct answer is 650 V.
