Morning fellas. I know from regular visits to this website that we have some rather intuitive Sparkie’s on here so I thought I’d join in the fun.
I’ve got a rather basic question to start with but also where some of you can hopefully show your tips and tricks.
Im currently working on a...

Hi...keen amateur here......don't crucify me for asking!! I understand Ohm's law and I understand the mechanics of measuring end to end on ring final and then joining incoming live to outgoing neutral etc, and I know that this configuration gives a figure of 8 (in fact can be straightened to...
HI everyone,
Is it acceptable to wire a hand dryer from a ring final in to a 13 amp FCU. The ring main in question has 30MA RCD protection.
Or, is it best to wire a new radial circuit for it??
There is a socket I can spur off that is easy to get to.
Thanks
Hi All,
Just looking for some reassurance on a job I've looked at today. My status is that I am trying to stay within the realms of 'Minor Works' until I get a bit of experience under my belt. Conscientious decision - but everywhere I go it seems that notifiable work is needed as well...
Hi Everybody
Why fuse is no longer use in Final Circuit Protection. Instead, Circuit breakers are used.
So far, I know that CB is more sensitive than fuse.
Can someone depicts any reason and their respective curves.
Thanks
Hi all. Love the forum by the way.
I do have a question though...
I have just visited a house (on a Sunday!). Customer is asking for additional sockets onto 32amp ring final. Circuit is 30mA RCD protected. Wiring is 2.5mm/1.5mm tinned copper.
Thought I’d better do a live Zs test.
Zs = 1.29...
Testing my extensions wiring today and noticed cpc fails continuity. Howevery I have continuity from outward leg to main earthing bar in CU
Any ideas how ?
So with megger leads they are not too happy in a kewtech socket tester so what do you do when you want to do this use kewtech leads on the megger? The megger leads clearly do not fit into the kewtech. Just use the plug lead?

Hi there
Been stuck on this for a while. What is the maximum r1+r2 reading possible on a lighting circuit in a domestic property. With a type b 6amp breaker.
Also if you guys could tell me about r1+r2 and rn Maximum readings for ring final.
Thanks
Hi all,
Just a question relating to SY cable and the use of SY cable. My boss his carrying out a EICR for a industrial premise and coming across a lot of SY cable. These cables are used for final circuits and distribution circuits. I know that BS7671 list SY cable as non - standard cables and...
Hi All.
I had a job which was going to be a 'quicky' fault finding and repairing a couple of sockets, then it came to the testing.....
The consumer unit gave me no cause for alarm but was all labelled up wrong, so it turned out there were far more sockets and square meterage on this ring final...
Hi all. I know there is a DIY forum but im really after your expert knowledge rather than fellow DIY'ers/amateurs.
With regards to replacing a section of a bedroom ring final circuit in a bungalow loft what is your preferred method of cable routing taking into account insulation and not being...
I am planning to move a socket outlet. The CU is largely unlabelled so don't know which 32 MCB to switch off. There are 2 x 32a MCB. All other mcbs are for lights (6a) and a dedicated immersion (16a).
To isolate the circuit, I tried switching off the first of the two 32a mcb which isolated some...
After coming across countless faults in domestic premises regarding ring final circuits, I reckon they should scrap em...
Gets frustrating when you go to check
continuity and there is nothing between each leg. Or you get a call to check a burning smell from the C.U and once again a broken ring...
Testing a ring final circuit today. R1+R2 is fine, same as end to end r1 rn and r2.
However IR test is coming back 1.87M ohm. I split the circuit and located a section (one side of the ring is clear >999).
The customer doesn't want any walls or ceiling touched. As this is greater than 1M ohm...
Hi,
Went to look at a job today where the customer reported the RCD intermittently tripping.
I did an RCD Trip test and it failed to trip on x1, x5 or ramp test, the mechanical button tripped it.
After a bit of further testing I discovered that the Kitchen RFC had an IR reading of 0.00 meg...
