Problem with 2 way landing whilst replace consumer unit

[bodge64]

I did ident all the conductors before disconecting the old fusebox, but as you described as " the cheshire 2 way" is exactly whats been done. I am doing the job as a favour for my wifes aunt and uncle, what would be the least disruptive way to rectify this?

Ok. I don't want to sound like I'm telling you how to suck eggs here but as a rule of thumb it is always wise to identify your conductor ends to make sure you know exactly what is what and I don't necessarily mean when you remove the old consumer unit but when you go to place the new one on.

Assuming that you have identified that your Line conductors and Neutrals are corresponding and are not mixed up/swapped between MCB's or Neutral bars then I would suggest that you run a separate Neutral from the Hallway to the landing light. To avoid nuisance tripping, at the landing light the Neutrals are put into a connector block, taped up and tucked into loft space. The new twin and cpc that you have run in goes into neutral connection. Not best practice I believe and will no doubt raise eyebrows to sparks reading this.
Please correct me guys if I'm talking rubbish.

As for minimizing mess, well that depends on the route you choose to take. Is there an airing cupboard on landing or some where you can put trunking up without it bothering customer?

I think that I have this right but I'm pretty sure in your initial post you don't actually mention if it's between the hall and landing light.

You say you've moved both lighting circuits to the same RCD side of the board... But have you moved both neutrals over to the same bar? Double check and be sure, no other reason while the RCD should trip when a switch is pressed.. If it does then I would do IR tests..

Did IR test on all circuits before installing but will check Neutrals when i go up tomorrow. I don't know how you guys do domestic work all the time, it would drive me nuts!

Good luck hope you get it sorted. Give us a shout when you know what it was. Oh and for the record, yes domestic does drive you a bit batty, especially in empty properties day in and day out
