RCD refuses to switch on (up)

[Midwest]

Is it my iPhone screen (small), or is there a blue wire going from the neutral bar to the earth bar. Haven’t got my reading glasses?

John can you post a pic of the house CU internals please?

Pete, been out. Picture attached. Flexi conduit coming up from under the floor. See the brown wire going into middle mcb and tell-tale blue wire going into neutral bar. Cheers.

Swap the N to the other N bus-bar

Swap the N to the other N bus-bar

I bet you are itching to go and do it ,hay Pete.

Why a 16A radial to the shed then a ring main on a 32A in the shed, wheres the thinking in that?

Also why have you energised before initial verification was carried out?

Anyone mentioned exporting the earth to the shed yet

Yes right

Need my glasses again. But I think the OP has garage supply neutral in the right one.

Edit, in the house CU.

I worked for years in electrical wholesalers and understand matters fine.
I reckon I do have a fault, however I cannot understand where. I tripped the in-house mcb and then disconnected the RCD, now when switched up it stays up.

Did you disconnect the load side of the RCD, i.e. remove your wiring?

The neutral is in the correct neutral bar, the OP has told us twice that the supply to the shed CU is from the non-RCD side of the house CU and the picture proves it.

Looks like its connected up correctly in the house.

1. Are you sure you have the correct neutral and line conductors in the supply side of the RCCB in garage unit? Can't tell from pic.

2. What are your IR results for the final circuits in shed?

 

[ChrisElectrical88]

Im thinking wrong neutral in the incoming of the RCD aswell.

Edit


For question 2 he 100% hasnt tested

 

[mattg4321]

Can you confirm your IR testing results OP. Or is Chris correct?

The neutral is in the correct neutral bar, the OP has told us twice that the supply to the shed CU is from the non-RCD side of the house CU and the picture proves it.

Easy Tiger. In any case I've already said all that, in a subtle way. So your guilty of plagiarism.

Keep up, you can learn a thing or two from me.

PS, thought I was mentoring you anyway. Not turned up at class for a while. Do ya wanna talk about things?

If those cables were dressed better, we might be able to see what's going where.

 

[Strima]

Correct polarity after the garage board?

 

[SparkyChick]

I'm not 100% certain as it is difficult to tell, but I'm another vote for the incoming supply neutral at the garage CU is in the neutral bar rather than the RCD incoming terminal.
