PV system was installed in January. Small company - very satisfied
with the installation.... but now ...
I didn't notice until quite recently that the electrician didn't have
a one-for-one fitting MCB (16A) and had used whatever he had in the
van. The box takes Merlin Gerins, and the 'bodged' in one was clearly
a mismatch causing distortion to the cover.
Two weeks ago I got a MG replacement to swap out the mismatching one,
and found that in order to get his MCB to fit the electrician had
trimmed back the lug on the input copper busbar. Although the MG one
seems to have a sufficient clamp on the reduced lug, I am concerned
I've been in contact with the company and the electrician has admitted
that he had to use another MCB type as he couldn't get an MG one, and
he may have cut back the lug. I have said I would like an independent
opinion on whether there is a hazard at their expense, but he is
insisting that the company should be allowed to rectify matters
Collectives opinion please.
