    Ring to radial

    Had a call out to a home where the RCD keeps tripping when lounge ,dinning and bed room sockets mcb is switched on. Fault traced to one of the legs from the consumer unit to 1st socket 0.2Meg ohm at best. cable size is 2.5mm T&E there are 10 double and 4 single sockets on the circuit. Reg 433.1...

    Volt drop calcs on ring main

    Hi Guys, I'm not into design etc and never have been really but how do you calculate volt drop on a distribution ring main circuit? Ring circuit say covering a large area supplying various loads/buildings. I was thinking split the ring and work it out as 2 x radial circuits, but 1 radial may...

    Hybrid circuits

    Morning all, been pondering quite a bit lately about Hybrid circuits,especially 13amp socket circuits, the likes of lolly pop rings etc. I don't want to get into arguments about the pros and cons and why people install them, that's been done to death, whether, I personally agree with this...

    Australian Plugs

    Hi, I had a nice little job of cutting 20 Australian plugs off appliances etc the other day and replacing with uk plugs... It occurred to me though, none of them had fuses?.. I have no idea how it works down under and just wondered if someone would kindly tell me why the appliances are not fused.

    immersion on a non dedicated radial

    I went to a job that the owner felt was a bodged job. It was basically a radial circuit wired at the start in 4.0mm T&E, and then it goes to a few sockets that is supplying a washing machine and tumble drier. From there it goes upstairs to the airing cupboard where it feeds a single switched...

    Ring or Radial....?

    Hi all, Im am soon to be installing 4 double sockets and possible 2 wall lights in a new conservatory. Was going to extend downstairs ring but a tad awakward and I'm not a lover of junction boxes if they can be avoided. The consumer unit isn't too far so just as easy to install a new circuit...

    radial circuit

    i had a couple of sockets put in about 12 year a go and was thinking of adding another for tv on wall and was looking under floorboards and it looks like its done on a radial circuit as it come straight from the fuse box and ends at the 2nd socket ,it is also wired to the up stairs socket fuse...

    Hi I'm new here! Have a question on Radial & Ring circuits

    I am a DIY and working on an extension on my home. I found out that one area of my house is on a 4mm radial for sockets on a 32amp mcb which I know is fine. Now the question is Can I safely continue wiring 4mm radial? Total length from distribution to last socket will be around 60metres with 12...

    Voltage Drop Branch of radial circuit

    hi guys Need some help in calculating voltage drop on a branched radial circuit. (13A design load 2.5mm cable)( cu to junction box 8m 2.5mm) for a standard loop in loop out radial it would be IbxDxmV/m/1000 this circuit has 2 branches from the junction box one/ 10m long ( 1 double...

    Commercial radial circuit

    Hi everyone looking to clarify something, had a tester onsite today testing circuits we've been installing the past few weeks, in his opinion he found fault with one circuit, we had wired a 30m radial circuit in 2.5mm 2core & earth fp200 on a c16 mcb. The cable was clipped direct throughout its...

    0.00 ohms r1+r2 on radial circuit?

    Hi all, I've tested several radial circuits and only getting 0.00 ohms on the r+r2 test (zero'd leads) 2 of the radials only supplies one socket each and are approx. 3 metres in total length. (zs 0.25 and 0.21) Another radial only supplies one socket and is appox. 5m in length. (zs 0.35) The...

    Cooker and Hob Installation

    I am currently renovating my kitchen and am considering swapping my standalone cooker for a hob/single oven combination. Would it be possible to use a dual appliance output plate on a 32A ring? The hob = 4.6Kw The oven = 3.65Kw or would they need to be on separate circuits? Thanks

    4mm half of circuit on 32a mcb

    Hi all, I did some work on a house the other day that had a circuit for sockets which was cabled in 4mm to half way in the house the split of it to 2.5 up to the sockets. It had a 32a breaker. I'm aware that you can have a 32a 4mm radial but that the whole circuit must be in 4mm. Using 2.5 on...
