Found the faults.
First one was a neutral wire worked free and contacted the metal casing of ceiling lights.
2nd fault was actually in a ring circuit. An appliance fault must have been the reason why the earth conductor melted through the cable contacting the neutral line.
Now I need to...
That's great thank you for contacting me. I am currently up north wiring up a chicken farm and hope to get something in London asap. I will contact you on your website .
yes that is true, and i got a figure of approximately .8 amps
0.6 amps on the downstairs lighting circuit and 0.2 amps on the upstairs lighting circuit.
unfortunately i never got round to finding the location of the fault,the landlord was funny and did not want to give access and i have been called to another contract.
what started the whole thing, was that the bathroom lighting circuit was not protected by RCD. when the circuit was put on an...
Traced the problem down to both the upstairs and down stairs lighting circuits. When disconnected neutral on these circuits the current meter fell to virtually zero amps.
Measured the resistance between neutral and earth conductors and got approx 6 ohms. If there is a difference in voltage...

Thanks for the helpful suggestions folks. These all seem like possible reasons and nothing to do with insanity. I will proceed to isolate the right circuit tomorrow and do the insulation and polarity/wiring checks . Will let you know the outcome.
The lighting circuit needs rcd and since the Consumer unit is damaged and dangerous it was best to change the whole consumer unit. So before powering down and ripping out the old CU. some basic tests to ensure there was no leakage that may trip the rcd and therefore delay outage in the...
It's a TNS supply.
Yeah I will try ripping out the neutrals to see which circuit to troubleshoot.
The house is lived in and I do not have keys to access rooms to do insulation tests as the moment. But will get round to it once I identified which circuit
Hi all,
This is really concerning.
Turned off all breakers in a domestic single phase consumer unit. With just the main switch on I measure a 0.8 amp current in the neutral tail into the consumer unit and virtually zero current in the Live tail. This is using a clamp meter.
One of the...
Hello, do you still need assistance, I am available on weekdays.
I have transport, and handtools and can start immediately.
Done my 17th edition, C&G Initial verification, test and inspection. and a C&G course of domestic installation.
