where we use stardelta starter and dol starter
Answers were Sorted based on User's Feedback
both are use in motor ,The purpose of stardelta starter is
to limit the starting current of motor.If the starting
current is low means we can use dol starter upto 5 hp
motor.above 5 hp motor we should use stardelta starter for
limit the starting current.
