I have check my lighting installation one by one and they are all working by connecting to an 13 amp extension. Today, i did the third circuit for 3 outside lighting. i will finish them on monday. i will not touch the distribution board anymore because i think it is faulty or damage how on earth the db all goes live when switch on.
i will just finish my wiring, then, do plastering, painting, flooring and etc. I hope my electrician will come next week or i get another one. i have been holed up
in Coventry for nearly three months doing my first buy to let away from London. Anyway, thank you all the comments and replies and I will keep you updated
