Can I adding a socket to a radial circuit?
The simple answer to this question is yes you can and this is known as a spur, or spurred socket, but there are a few things that you nee to be aware of. You can add one further accessory or socket off of a single socket present in a radial circuit and no more.
How many sockets can be on a radial spur?
Non-fused spur can only have one twin socket or one fixed appliance and a fused spur can have as many sockets as you require but care should be taken to ensure that the total load does not exceed the 13A fuse within the switched or unswitched-fused connection unit.
What is the maximum number of socket outlets for a radial circuit?
Radial Final Circuit
Live is connected to live, neutral to neutral and earth to earth at each socket outlet. The cable used must be at least 2.5 mm2, and the maximum number of socket outlets per circuit is ten. The radial final circuit should not supply more than two rooms.
How many sockets can you have on a 20A Radial?
unlimited
The number of socket outlets, is unlimited for a floor area of up 20m2 with any type of circuit protection of 20A using 2.5mm2 PVC Copper cable or 1.5mm2 m.i cable. The total number of fused spurs is unlimited.
Can I spur off a socket twice?
A spur can be connected to an existing socket, on either a ring main or a radial circuit, providing that socket does not already have a spur. That is only one spur per socket is allowed and the number of spurs must not exceed the number of sockets.
How many amps can a 2.5 Radial take?
Answer: It is acceptable to install a number of sockets on a radial circuit using 2.5 mm cables protected by a 16A circuit breaker – provided that the expected connected load does not exceed 16A.
Can you use a junction box on a radial circuit?
It is possible to use a higher amp rated junction box on a lower rated circuit, but never the other way around – To summarise: Ring mains and radial circuits = 30 amp. Lighting circuits = 20 amp.
Can I extend a ring main myself?
It is not particularly difficult to extend a ring main but you must remember that certain rules apply about the floor area and length of cable one ring main may serve and use.
What happens if you spur off a spur?
The reason for not running two spurs from the same spur “point” is that it can lead to possible overloads in that one leg of the final can become unbalanced and exceed the max. allowed amps for a bit of 2.5mm if the tap off point is near the cu.
What is the difference between a ring main and a radial circuit?
Ring circuit wiring offered a more efficient and lower cost system which would safely support a greater number of sockets. The lower costs aspect was related to fact that wires with a smaller diameter could be used, compared to radial wiring.
What are the disadvantages of a radial circuit?
Disadvantages: Requires a lot more cable as every outlet has to wired back to the distribution board. Can be far more complicated to add additional outlets because of the need to run new cables back to the distribution board.
Are radial circuits legal in UK?
16th Edition (reference only) – NOW superseded by the 17th Edition IEE Regulations. Two types of radial circuit are permitted for socket outlets. In neither case is the number of sockets to be supplied specified, so the number will be subject to the constraints of load and diversity.
Do sockets have to be on a ring?
The UK is the only country in the world to work with Ring Mains, or Final Ring Circuits and without the correct testing equipment and knowledge of procedures it is impossible to tell the difference.
Can I add a socket to a ring main?
The easiest way of connecting into a ring circuit is to run a spur cable from the terminals of an existing socket – but you can’t connect it to any socket. The IEE Wiring Regulations are very specific about this. You mustn’t run a spur from a socket that’s already on a spur, or that already supplies a spur.
Are ring mains being phased out?
Yes, ring mains (more correctly called ring final circuits these days) were and still are the norm for most UK dwellings.
How do you extend a ring circuit?
The best way of using junction boxes to extend a ring circuit, is to find the length of cable between the two sockets on the existing ring closest to the desired extension area. Once located it can be cut in the middle giving two lengths of cable from the existing circuit to use in the extension.
How do I add an extra electrical socket?
Quote from Youtube video: So we're basically extending the ring. Goes into that socket into that socket. Comes back and then goes off on the cable that then goes to the other sockets.
Can I add to a ring circuit?
There are two ways of extending a ring circuit, either by adding junction boxes or by using existing sockets.
