In a ring final circuit for sockets where does the loop begin and end?

• A. It starts and ends at the distribution board, forming a complete loop.
• B. It runs from the distribution board to each outlet separately.
• C. It is a radial feed from the distribution board to the outlets.
• D. It runs in a star topology from a central point.

Answer: (A)

In a ring final circuit, the path forms a closed loop that starts at the distribution board and returns to the same point. The live and neutral conductors run out from the board through the outlets and then come back along the other conductor to the board, effectively making a complete circuit. This looping back to the source is what allows the circuit to be supplied from both directions and enables using smaller conductors while still carrying the load. A radial feed, by contrast, goes from the board to outlets without looping back, and a star layout would have outlets tied separately to a central point rather than forming a continuous ring.
