Hi,
I am studying for me 91 and am currently practicing on my home. I have found that my garage circuit consisting of a small 2 way CU with 1 of each; ring and lighting circuit (no RCD). I expected to see this circuit connected to the main CU through its own CB but in fact it is connected to...
I am carrying out the continuity for a ring final test for a single phase TN-S system. When doing the end to end Neutral I don't get a reading!! What is wrong here and what Code does apply (Code 1-3)?
Many Thanks.
Can we carry out the continuity test for the ring final by connecting the line, neutral, and cpc end to end at any socket or do we have to identify and disconnect the conductors at the C/U? I am aksing as i think it is much easier to link the line, neutral, and cpc end to end at any socket...
Hi
Just doing end to end test
line - line 0.51ohms seems fine
cpc-cpc 0.91 ohms seems fine
But N- N reading is coming up 1.46 Kilo ohms ??!!! any thoughts
I am doing 2392-10 and am fairly green.............be gentle

Hi guys, Would be interested to hear your thoughts on the following.
I had to change a CU in a hoarders property in January which proved to be quite a challenge. CU was damaged with accessible live parts so I had no choice. Clutter was extreme with hardly any access to some rooms so couldn't get...
Just pondering my voltage drop calcs for a fused spur off a ring final. Additional circuit will be around 15-20m long so I though I should do this properly....
My problem is calculating the voltage drop in the existing ring to the point of the spur which of course depends on distribution of...
Why is it when you cross connect the conductors at each leg and then test continuity, the result is one quarter of the combined resistances of the legs? I am usually pretty good at seeing how/why calculations work out, but just cannot in this case get my head around why the value measured is a...
Hi Chaps
I am just starting out in this profession and eager to learn so sorry if questions seem a bit daft.
If you need extend a second floor ring main which runs through four rooms by a further two sockets , and you have no idea where the first or last socket is where do you break into the...
Hi all,
Had a call from a customer saying her oven had broken. When the oven engineer went out he fixed the oven but told her she had "no earth on her kitchen sockets".?!?! He told her the other circuits ie the lounge and cooker, were ok but no earth to the kitchen ring final?! How can this be...
Hi i have been set some home work from college to find out why ring final circuits are dangerous. I know the obvious that if one leg on the ring breaks it will not be a full ring and the 32 amp mcb will be too big for the cable as it will only be able to carry about 20 amps with out it been a...
TN-S Domestic, 30mA RCD, 32A MCB, 2.5mm T&E I've been asked to install some socket outlets and connect up previously installed underfloor electric heating (2400W) plus some wall lights in a Conservatory project that got built, but electrical works not completed by the the time the building firm...
Went to look at a job today in a one bedroom purpose built flat which consists of two lighting circuits, a single ring final circuit for the sockets, a shower circuit and a cooker circuit with a single socket outlet. The customer wanted to upgrade the old fuse box to a CU in what on the surface...
Morning All
When testing end to end resistance of r1, r2 and rn. Is there a number you can multiply the r1 reading to check that the r2 reading is ok? For some reason I seem to remember you can.
also, when tails enter a metal enclosure, they should enter through the same knockout/entry...
Hi,
Just browsing through OSG (living the dream!).
Why is an A1 ring final circuit only protected by a 30/32A breaker when the max current carrying capacity of a 2.5 cable is 27A? (page 134 of OSG, column 6). Apologies in advance if I'm missing something very obvious. Thank you
Hi chaps,
Been searching thru posts but to no avail. I have one ring final with IR of approx 0.98 Mohm L-N , 1.48 Mohm L-E on 500v. I later found one appliance plugged in (dishwasher) but didnt have time to re test. The fcu above worktop was switched off for this applince but it was still...
Had a Minor, Non Notifiable to do for a friend. Moving 2x sockets in the bedroom. After looking at it and from a response on here, took new legs up into the loft (it's a top floor flat) and joined in a 30A JB to the Incoming legs off the circuit.
Came to test it, as was supplying a BS7671 MW...
Something I've wondered about for a while...
If you had both legs of a RFC, in say T&E or singles, running in the same conduit, so basically touching, would you need to apply the appropriate correction factor for grouping?
Doing a PIR lately and found no continuity on one of the ring final neutral circuits. I am not familiar with fault finding and would appreciate any help and hints. IR test on the circuit passed.
