Engine 2014: Electricity

1. A A trigger fuse, when blown, trips the motor on low voltage, providing added protection beyond the capability of the under-voltage relay.
2. B A trigger fuse, when blown, trips the motor on single phasing, providing added protection beyond the capability of the differential, single phasing characteristics of the combined overload relay.
3. C A trigger fuse, when blown, trips the motor on sustained overload, providing added protection beyond the capability of the over- current, inverse time characteristics of the combined overload relay.
4. D A trigger fuse, when blown, trips the motor on a ground fault, providing added protection beyond the capability of the ground fault characteristics of the combined overload relay.
