- If a motor starter is installed according to directions but will not start, what is a common cause for the failure to start?One reason for the use of a reduced voltage starter would be to reduce the high starting current drawn by the motor. True or false?Why should the motor be run for a period of time following checkout?
- what must be done to prevent excessive motor current?A selector switch and two - wire pilot device cannot be used to control a large motor directly but rather must be connected to a magnetic starter. Why this is true.?If the contacts on a manual starter cannot be closed immediately after a motor overload has tripped them open, what is the probable reason?
