Bussmann Group Motor Protection Guide



The NEC® section 430-53 allows two or more motors and other
loads to be protected by the same overcurrent device when
specific requirements are met. The BUSSMANN Group Motor Protection
program is a quick and easy to use program that will tell you
if you meet the requirements of group motor protection by asking
a series of questions. Once it is determined that you can use
group motor protection, you must still meet the group switching
requirements of NEC® section 430-112. The BUSSMANN program will
ask another series of questions to see if you meet these requirements.
