RING CIRCUIT FAULT FINDING - FINDING BREAKS IN THE CABLE - TESTING METHODS - HOW TO TEST THE CIRCUIT
Рет қаралды 12,402
11 ай бұрынIn this LearnElectrics video we look at ways of finding breaks or damaged wiring in a ring circuit. The methods you might employ if a periodic inspection of a premises has identified problems with the circuit. If you’re new to the trade or perhaps if testing is now part of your job description, this video will help.
We’ve had lots of questions posted …
How do I test for broken wires in a ring circuit?
Or … During an Inspection and Test there is no continuity on some of the end to end tests.
How do I find the problem?
What readings should I get at the sockets and how can the resistance readings help me to find the problem?
And lots more, including how to test without a wander lead

Great video Dave, I like to use the method you described here. The only additional thing I do is put a piece of insulation tape on top of the socket with the measured resistance value written on it. I also then go back to the board and link the other end, then use a different colour tape and start writing resistance values on socket fronts. Then if the ring isn’t logically wired, at least you can start removing the two sockets with the “highest resistances” first. I find it very effective especially if you’ve no idea how the ring has been previously wired.

Best of luck Dan, you can do it. I know lots of folk who started in their late 20s through to 40s and they now have crackin little businesses. Stick with it, learn a little every day. It takes time, but time is what makes you good. Dave.

Very good. Nice and simple. The hard bit is often the mystery of the socket runs and sequence along with spurs
@learnelectrics4402 9 ай бұрын
Always draw what you see Tony, take loads of notes and save them in case you go back. Sometimes the only way is to disconnect at the board and resistance test on the most sensitive scale that your multimeter will go to and look for the ohms to increase as you move along the wires. Thanks for the input. Dave.

Excellent video, as always. As a suggestion, it might be worthwhile to link in description to your video that shows how to map out the path of a ring circuit, in case it’s not as logical a path as shown here. My own house has a strange ring, with two adjacent sockets in the lounge having a path upstairs (serving all sockets) then back down, rather than just being joined to one another…. Linking up that other video with this one makes a useful complement.

Hi Dave, issue at home please could you help, I was washing car with jet wash, when I went to unplug I got a very noticeable shock , a good tingle in my fingers that made me pull away quick… the plug was wet as I’d mistakenly left the socket lid up and it had got pretty wet as were my hands. I’m guessing some electricity was leaking up through the moisture. The sockets are on an RCD but it never tripped? I tested the RCD and it trips in time and tripped at 25ma on a ramp test. Any idea why it wouldn’t have tripped? I’m guessing there was at least 25mA of current leaking as I got a good tingle so should have tripped ?
@learnelectrics4402 11 ай бұрын
If you've tested it and it trips ok, then I would say that the shock current you felt was a lot less than 30mA. they do say that a current as low as 10mA will make you sit up and take notice. Also, if you were wearing rubber soled shoes that would reduce the shock current too. Lesson learnt I guess. Hope you're OK. Dave.

Is it possible to use a ring circuit for lighting purposes?
@learnelectrics4402 11 ай бұрын
Nothing wrong with that, except that for most lighting at 6A or 10A breakers, the T/E cable easily copes with the demand current as a radial.
@tonybaker7453 9 ай бұрын
Yes but use a 3A, 5A fused spur to protect the additional lighting circuit cable.

How do you identify incoming and outgoing pvc singles at the board?
@learnelectrics4402 11 ай бұрын
Have a look at the video on the link below. When you do the crossover, a correct crossover will be R1+R2/4 at each socket. If you have incoming and outgoing mixed up, you will get very different values at each socket. kzfaq.info/get/bejne/n7xxeKd227Szknk.html

@henrystevens2258 11 ай бұрын
In theory this is a good way but the problem with doing it this way is as the resistance rises you think this the wiring route that as been installed but the sockets can and in most cases in my experience can give false results because of there age are how they been used over the year ,so after many times of fixing breaks in rings it really is better to remove the sockets of the wall.
