Whats wrong

[dnjr]

Saw this in pro electrician and am unsure what's wrong. I know I'm sticking my head over parapet here but what's wrong in the photo
Thought it may be that the L. and N have been swapped but didn't think that would matter. Mostly use Hagar boards and they say it's ok

It looks like the RCD neutral has been linked out between the incoming & outgoing side.

What's the black wire doing? Daz

Hardly a polarity issue though as the magazine states?

I reckon the 'inspector' never noticed the wire Daz

True, but the brown goes to the same side as the bus bar, and the blue to the blue - I mean, I failed nursery level colouring, but it's quite obvious isn't it the wires are the correct way round?

I think the problem might be the whole board is being protected by one 30mA RCCD

Not as worrying as the bypassed neutral though surely. Daz

Wait, are you suggesting that it's okay to have your line and neutral the wrong way round or am I reading this wrong?

 

[billy10]

I think the magazine inspector is the one with his wires crossed.

Sorry, i couldn't resist!

 

[telectrix]

but is it bypassed? blue incomer at top, blue out from bottom to N bar. can't see what the black is into though.

 

[billy10]

I could be seeing it wrong but it looks like there's a rogue black wire from the bottom of the RCD to the top as well as the blue neutral tails.

 

[DPG]

Definitely looks like a bypass. Unless it's just passing behind the RCD, but it looks like it goes into the bottom terminal to me. Daz

 

[dnjr]

Hurray. Not just me then. I thought it was bypassed but why on earth would you do that
thanks to all for contributing

Maybe it is the way the picture has been taken, but is that a CPC going into the second mcb?

 

[dnjr]

Looks like it but I was looking for a neutral fault. Surely not

 

[Lucien Nunes]

I see the black sneaking around the RCD and wonder, what could possibly be the point of bypassing ONE pole of an RCD? Certainly won't help keep the supply on...

Maybe it was 5pm on a Friday lol

If you read the note it says "annoying neutral faults, all sorted now"

My guess is the RCD has been by passed on the neutral side by that black wire in an attempt to get round a problem of nuisance tripping caused by an existing fault that has not been properly identified.

Though the inspector's comment is either a mis-print or he is as brain dead as the guy who fitted the bypass.

My point being that bypassing one side only will force it to trip on any load, not stop it tripping, so it will be more or less impossible to get a supply regardless of whether or not there is a fault. I.e. the system would surely not have been left like this. Unless the line is also bypassed but we can't see it.
