rcd won't hold light circuit.

The simple way is to contact an Electrician.

 

so you energised the circuit with out dead testing?

where's the electrician who changed the board?............

 

Obviously not or you wouldn't be asking the question.

Kind regards

1 - Yes he did.

2 - No electrician, no notification etc. DIY job is my guess.

Kind regards

 

deserves to be stung with a horrendous call out charge then lol

 

It is likely to be that you have not carried out correct testing and inspection both before and after replacing the CU.

You do seem to have a little bit of a history regarding lack of testing, no certs for CU replacements etc.

Get a qualified, experienced spark in and pay the man for his knowledge and experience.

Without initial verification of the work it is impossible to claim that it will be safe.

 

Sparks don't cut corners because they understand and know the dangers. Cowboys and 5 day wonders cut corners!

If you want it sorted, like I said, get a qualified, experienced spark in. Learn from it and stop cutting corners when you take these jobs on.

Yes it may be faulty low voltage lights. Disconnect them. Carry out IR tests. If all is clear then suspect the low voltage lights.

Maybe his test equipment extends to £2 ohm meter from Aldi

 

Not the first time though is it.

Obviously not.
