This simplifies servicing motors and facilitates monitoring of control systems and facilities mechanical and HVAC system operations. NECA 402 has been meticulously revised to include the latest revisions in the National Electrical Code (NEC)®
while continuing to deliver most current and highest level of quality and performance criteria for motor control center installations. This standard helps contractors, designers, and installers get the MCC installation right the first time.
