3 TIER BREAKER INTERLOCK SCHEME FOR DIFFERENT SOURCE OF POWER, VFD AND STARTER HOOKUP LOGICS

Question

Accepted Answer

The 3 tier breaker interlock scheme is used to ensure safe and efficient power distribution from different sources.

The scheme involves three levels of protection to prevent power overload and equipment damage.
The first tier involves interlocking the main breaker with the emergency stop button to quickly shut off power in case of an emergency.
The second tier involves interlocking the main breaker with the VFD and starter to prevent simultaneous operation and overload.
The third tier involves interlocking the VFD and starter to prevent damage to the motor and equipment.
Examples of different sources of power include generators, utility power, and renewable energy sources like solar panels or wind turbines.
