Section 8—Mag-Gard, PowerPacT, and TeSys Motor Circuit Protector and Circuit Breaker Settings

The National Electrical Code® (NEC®) and Canadian Electrical Code (CEC) require that magnetic starters, used in combination with adjustable magnetic triponly circuit breakers, have an overload relay in each conductor. MagGard, PowerPacT, or TeSys BV4 Motor Circuit Protectors are the standard motor circuit protectors used in Model 6 MCCs.

Some Model 6 MCC motor control units are provided with PowerPacT M or P frame circuit breakers. The breaker trip units are set to the required amperage setting for the motor control unit in the factory. The breaker instantaneous trip settings may need to be adjusted to permit motor starting in some cases.
