How are spurs connected to a ring circuit?

• A. From the front by tapping the hot conductor into an unused terminal.
• B. By connecting to the neutral bus.
• C. From the back by wiring them from an existing socket into either 1 unfused socket or as many fused sockets you would like.
• D. Using a standalone spur box.

Answer: (C)

Spurs from a ring final circuit are branches that start from an existing socket on that ring. The normal and practical way to create a spur is to connect from the back of an existing socket on the ring and run a short length of cable to feed new outlets.

From that point, you have two common options. If you only need one extra socket, you can feed it as an unfused spur directly from the back of the existing socket. If you want to supply more than one outlet, you feed them through a spur box (a fused spur unit), which provides protection for the multiple fused outputs.

Tapping the live conductor from the front of a socket or wiring into the neutral bus isn’t how spurs are intended to be created, and a standalone spur box, while valid in some setups, isn’t the standard method described here. The key idea is that a spur is taken from the back of a socket on the ring, then either unfused for a single new outlet or via a fused spur to multiple outlets.
