What is the meaning of preferential trip? Why is it provided
by

1 Answer

Answer :

Preferential trip is a kind of electrical arrangement on ship which is designed to disconnect the non-essential circuit i.e. non-essential load from the main bus bar in case of partial failure or overload of the main supply. It lets the critical loads run (like steering gear) and trips the non essential loads (like AC and galley) and is a safety feature.
