New Consumer Unit Installation - L&N Reverse at the sockets

[delano]

I've had issues with BG boards as well. I only use quality brands now. More expensive but at least I have more confidence when installing and no call backs or complaints from clients.

try the BG boards. similar price to MK, but better quality and better looking. ( a bit like me, i suppose ).

What was the fault on the RCD?

No tripping at x 5

Thanks Mate sorry if I have missed something, just got me wondering what does failing the trip test have to do with reversed polarity?

Normally, nothing but it indicated a faulty RCD. Internally, it caused a L-N fault, also caused supply voltage on earth.

Agree the non trip would indicate a duff RCD the other faults you mention, I'm not so sure.

As stated, it was definitely the RCD. Once changed, all faults were cleared. Have reported it to MK and they are aware of the problem.

Would be great if you could relate what MK have to say on the matter.

They did not give me a definite reason, only that they are aware of faulty RCBOS and RCD'S. Will keep you posted on any updates.

I came across a L an N reversals only a few months ago.
Was called out to a kitchen circuit tripping... found a screw in the wall and into the cable. But as part of the testing I noticed the L and N were reversed in the entire house.
On close inspection I found the incoming feed had been reversed by the electrician who had connected the solar panels some months ago. I rang the company and sent them some pictures. They said they used a local electrician as theirs was too busy and as such can't accept responsibility. I reported them to local building control....I heard nothing.

Jeez, I don't believe this has got to nine pages.

Most of us are well aware of the well publicised issues and recalls of MK RCBO's

Please tell me YOU fixed the problem as a matter of priority?

 

[Paul228]

Of course I fixed it, just after I came off the phone with the solar panel company.

 

[Specialist]

You sure now ? You didn't wait 10 days before you went back to fix it

 

[Paul228]

Lol.
Loving the tongue in cheek sarcasm.
The best of it was, I billed the solar panel company a,silly amount and they paid it within two days. Based on how long it took and what they paid, I was on par with yaya toure in terms of wages.

 

[Specialist]

Sorry buddy, Sarcasm wasn't aimed at you just the thread OP.
Glad you got well paid for it, well deserved for finding the problem & actually sorting it.

 

[Paul228]

Being a,northerners, we use sarcasm 24/7, so it's all good.
