this is a cable that is connected to a ring to supply electrical energy to one or more socket.

A spur outlet is a circuit that does not have a secondary path and is not part of the main ring. Spur sockets can have one cable connected to earth, live, and neutral.
Extensions to a ring-main are made by running a spur from the nearest socket.
spur evolves from spurious terminology.In electrical terminology it is denoted by a range of frequency through which any electrical circuit (specaially in case of RF and microwave circuits) is operated.
A spur is an extension connected from some point along the main circuit of an electrical installation. Spurs are sometimes called 'tees'.
A spur becomes necessary in electrical installation when additional power outlets are needed beyond the existing circuit capacity. It is typically used to extend an existing circuit to provide power to appliances or devices in locations that lack sufficient outlets. A spur must be properly fused to ensure safety and comply with electrical regulations, and it should not exceed the load capacity of the existing circuit.
As posted, the question doesn't make much sense - do you mean spur sockets, rather than plugs? Either way, it will depend on local regulations. In the UK, you can fit one socket on a spur from a socket on a ring main.
The Diamond Spur Rodeo was held annually in Spokane, WA. It was part of a circuit of rodeos in the Pacific Northwest including Ellensburg Roundup, Omak Stampede and the Pendelton Roundup.
Answer for UK, Europe and countries running a 50 Hz supply service.A ring circuit has two routes to each outlet, a radial has only one.
If you are talking about an electrical ring main it can be as long as you want it as long as it returns back to the circuit breaker with the other end of the cable, which if you didn't return the 2nd end of the cable to the circuit breaker you would have a radial circuit.
Yes, you can spur a double socket from a PIR light using 2.5mm² cable, provided that the circuit is rated to handle the additional load. However, ensure that the total load on the circuit does not exceed the rating of the PIR light and the circuit breaker. It's also essential to comply with local electrical regulations and standards, and consider consulting a qualified electrician for safety.
