	Dear Friends, Please tell me how to calculate the cable size for specific power. is there is any formula. Pleasec tell me And also tell me in single phase motor, a capacitor is used in starting winding, it is observed that by increasing the rate of capacitor the speed of the motor is also increased. Please tell me is there is any effect on motor if i increased the capacitor rate. If no then tell me upto what extent i can increase the rating of capacitor. Kishore Kumar

	<...Please tell me how to calculate the cable size for specific power. is there is any formula....> British Standard 7671. <...in single phase motor, a capacitor is used in starting winding, it is observed that by increasing the rate of capacitor the speed of the motor is also increased. Please tell me is there is any effect on motor if i increased the capacitor rate.....> The starting winding is usually switched out-of-circuit after the motor has run up to speed. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856
