Talk:Electrical Circuit Faults

This is a work in progress: that ultimately could include information not only on common faults, but also tracing and fixing them)

Please do not rely on any information in this article yet. It has not been checked, peer reviewed, or even proof read

various changes

(Mainly FAO John Rumm)

In the Wiki way I have made changes to your excellent article rather than merely suggesting them. If you don't like some you can change them back. If you don't like any you can revert them all (go to the history page, select the previous revision, edit it and save it without any changes (except a note in the Summary to say what you're doing). (You may find this technique useful for reverting spam on the talk page, which I see you've been diligently doing. Oh, so maybe you already know how to do this ...).

Well done John!

Thanks for the tweaks, you are right it looks so much better in English! ;-) (Its easy to get carried away getting all the stuff you want to say down, such that the language can get a bit hammy in places).

Not spotted anything that I would want to change back either....

--John Rumm 01:20, 17 May 2007 (BST)

Poxy search and replace ;-)

Yup, sorry about the metre/meter did a search and replace and forgot about the use of multimeter in there!

RCD tripping

Sorry to bother you but i have a problem.I installed a consumer unit today,and connected the shower to the new rcd.However the shower stays live for roughly ten seconds then trips.What could the fault be?Any feedbakc would be greatly appreciated

Yup, post a question in the group, but also have a look at the main RCD article. --John Rumm 19:07, 20 December 2007 (GMT)

Circuit faults change

One of the recent edits remove the comment abut localised heating and dimming of lamps etc on observable behaviour for faults on a ring.

I am content to lose the dimming one, but feel the localised heating should remain since one of the possible L/N lose connections is not between the wiring connection to the back of the socket, but could be between plug and socket itself due to dirty terminals or poor spring tension in the socket.

--John Rumm 16:44, 14 August 2013 (BST)

I guess we ought to clarify it...

• In the case of a poor contact anywhere in the cable connections, the ring circuit wipes out the problem. The alternative low R path means no significant heating at the bad connection, and generally no fire risk
• Faults within the socket itself are of course no different with ring vs radial
• V_drop and dimming are not significant issues from one bad connection with a ring cct
• By converting the most common faults into trivial issues, the ring circuit is a significant advance in safety & reliability.

Socket Tester

The article currently includes "A basic socket tester is also invaluable. For some tests a 13A plug is also useful.", embodying a direct link to a Farnell page which is no longer there. The intention must have been to refer to a modern version of what I used to use at work, which was like a 13A plug with a neon+resistor between each pair of pins. A Google search revealed many different-looking but similar ones at a very wide range of prices. I assume thaat the cheapest are likely to be shoddy and the most expensive to be unnecessarily costly.

Perhaps some expert could alter the link to point to one that he/she knows from personal experience to be reasonably good in both quality and cost?
