FFS listen to you all !!!!! how would you like it if every installation that you carried out was open to investigation on here ? OK I dont think the bloke has covered himself with glory, but I guarentee that if you put all your installations on here that someone would be able to pick fault with something
If we did something like that we'd get laughed out of town or lynched.
I think there's serious safety issues and at best it should be double checked by a competent installer, including the wiring.
