Nope - I said nothing about 'rejecting'. I suggested that the OP should question whether they should be using an electrician who adopted unconventional designs and I think that is reasonable advice to someone without technical and regulatory knowledge. You are essentially arguing about whether or not I should have emboldened the words that I did - and maybe I should have had more sense than to do that, knowing how easily quibbling can arise here....on the other you tell someone to reject an electrician who does do that if his thinking results in something unconventional but soundly engineered.
Kind Regards, John.
