I read in several threads on the topic of radial circuits (not necessarily on this forum) that, although a 32A protected circuit has to be wired in 4mm cable, "spurs" may be taken from a socket on the circuit and wired in 2.5mm cable. As I see it, under my proposed design I am simply replacing the radial sockets with junction boxes. You can extend the radial circuit with or without the junction box, however the total load is limited by the 20 amp breaker. . Extend the circuit as a 32 amp socket radial circuit using 4.0 mm twin and earth after the junction box. The circuit needs to have 30 mA RCD as well as a 32 amp circuit breaker, this is not really a DIY job. .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; Junction Box Terminals and Wiring. Junction . Would there be anything preventing having a radial circuit feeding sockets such that a single cable was used for a socket drop from a 3 way junction box in the loft? So CU feeding junction box and the junction box feeding socket and subsequent junction boxes/sockets in the same way.
The example is as follows - you have a circuit coming from the CU on a 16amp radial, rather than just go from one to the other repeatedly could you not use a junction box installation method. As long as the box was accessible. And yes, 20A MCB for your radial as well as RCD protection. Do bear in mind what EFLI wrote- if you're lucky you'll find a local electrician who will come out, look at the job and your proposed cable runs, decide where the cables need to go, what sizes, safe zones etc etc etc. then let you throw the cabling and backboxes in, then come back and test, terminate and certify.
The lighting circuit is wired using junction boxes. Socket circuit: • Four double sockets • A fused switch that goes to an outside IP66 single outdoor socket. In the garage I have powered: • CCTV (one plug for the DVR and one plug that splits the 12v power to the four CCTV cameras) • PC monitor – for viewing CCTV locally, if needed. a radial socket circuit wired in 4mm cable protected by a 32 amp circuit breaker am i allowed to take a spur from the 4mm cable using a junction box and 2.5mm cable to a double socket if so can i take 2 spurs from the same junction box again with 2.5mm cable to . For a circuit providing power to sockets for the bedrooms, either will suffice as the electrical demand is typically not as high as in other areas such as kitchens. Also of note, junction boxes have to be accessible and are potentially an headache further down the line. It is better to have a cable as a continuous length than use junction boxes. In general, these boxes are used as a way of transferring power from one source to somewhere else. Junction boxes are rated in amps, and it’s very important to choose the right box for the right job. Have in mind that a ring main and a radial circuit will need a 30 amp junction box, while a lighting circuit will do fine with a 20 amp junction .
Hi, I am planning on adding a couple of extra lights to an existing 1.5mm radial light circuit. in my enthusiasm I bought some 1.5mm twin and earth and some junction boxes and was quite happy. But, I bought a 1 mm heat resistant 3 core cable to run form the junction boxes to the light fittings. I suddenly wondered if I'm required by regs to use 1.5 mm flexible cable? I want to install a PIR security light on a garage, the light comes with around 700mm of outside rated cable. Which would you do: 1) Fit an IP rated junction box on the outside wall, rear fed with T&E from the existing garage lighting circuit and then connect the light with a gland etc to keep it all as weatherproof as possible. or 2) Drill a hole in the wall and put the .
On the fuse board there is a thick single cable going into the 30amp fuse. Neither me, nor the electrician checked what was in the junction box, we only checked the fuse. So it was decided to extend the so called cooker circuit as radial in 4mm cable. But later we found that terminated connection in junction box was a 2.5mm ring circuit.
If the junction won't be accessible then you need to use a maintenance free junction box (or use soldering or crimping, but those aren't options I'd generally recommend to the diyer). It seems that the makers of maintenance free junction boxes have each taken a different approach, leading to different manufacturers products being better in . This would put all 6 lights on one breaker, but I'd need to do a junction box as described - 1 feed in and 3 feeds out. By spur I just mean a point where the radial circuit branches out, rather than going in a straight line from box to box. If you think of one of my lighting runs as the main radial circuit, I would have 2 spurs at the junction box. The electrician I found had a look at the wiring in the garage and said I have to use ring circuit otherwise the fuse will trip. My current wiring in the garage is the a 2.5 mm T&E cable going through a junction box which splits .Radial circuit with junction boxes. Anonymous user 3 February 2015 - 10.56 AM. I have a kitchen on concrete floor. Sockets need to be fed from above. Is it possible to feed each of those sockets with a single cable running from a junction box on the ring? The ring will only have these sockets on it all fed from junction box system as in. a .
Spur using a junction box. If there is no socket outlet nearby, an alternative is to use a junction box. This is similar to the previous method, but instead of connecting to a socket, a junction box is connected into the ring and the spur cable attached there. Junction box wiring. A three terminal, 30A junction box is required. [quote="Sparkydelux"]Hi, I would like to know if it is permissible to wire a radial 20W downlighter circuit via a junction box. BUT,The junction box is located at the centre of the run therefore my question is, could I wire up the lighting circuit so that it comes out of the JB and goes different ways (still being switched by the switch) or do I have to run it so that I loop around as .For a lighting circuit use a 20amp junction box and for a ring main or radial circuit use a 30 amp junction box. Terminals . Junction boxes have 3, 4, 5 or 6 terminals and the number required depends upon the application. One thing to watch out for with the number of terminals, is the type of terminal used. Two basic types are available:
I have a radial circuit supplying electricity to the garage (part of the house). It's on a 20amp breaker, uses 2.5mm cable. It currently only supplies a single socket. Before anyone asks, its 100% a radial circuit. 6 months ago I had an electrician install a new consumer unit, and the testing/certificate that followed states this.The initial plan was to join this in an outdoor junction box and run that to an outdoor socket on the shed to use for tools and cutting the grass etc. The wife has now decided she'd like the tumble dryer putting in the shed. . You can have as many sockets downstream of the FCU as you want, and in any circuit layout (radial circuit) as the .
