	The first step in performing motor calculations is to determine the motor rating. It is extremely important to note that most electricians use the nameplate on the motor to perform this task which is wrong. Use the information in section 430 referring to the proper table and guidelines. The nameplate on the motor is used to determine the overload protection.
