The earth fault return path for a TT system is
A) The general mass of earth
B) The earthing conductor and the general mass of earth
C) The protective bonding conductor, the mass of earth and the earthing conductor
D) The earthing conductor, the earth electrode and the general mass of earth

Question

Quizplus · Accepted Answer

In a TT system, the earth fault return path includes the earthing conductor, the earth electrode (which is specifically installed for the system), and the general mass of earth. This setup ensures that in the event of an earth fault, the fault current has a path to flow through back to the source, facilitating the operation of protective devices.
