Re Part P Certification. Does a third party have to physically test an installation himself or is it sufficient to trust the test evidence of the electrician that did the work. I have been asked this by a neighbour and whilst I once knew the wiring regs I am no longer up to date (and not practicing). Thanks
A 3rd Party Verifier has to be appointed before the work starts. They then have to inspect the 1st fix and point out any non-compliances for rectification.
On completion they have to inspect and test the installation and issue a special certificate and notify the LA.
It could hardly be otherwise given 641.1Every installation shall, during erection and on completion before being put into service, be inspected and tested ... (my emphasis)
Not something that I would want to do for a living!
Now then, what would you do in this situation? T&E clipped direct to wooden battens in a workshop/garage. Everything on display and all done very neatly. Problem is that Mr Self-builder had the cables entering all the pattress boxes from above. Oval cable, square hole; just room for that paper clip to squeeze in the corners, so not, strictly IP4X. ? You or I would have brought the cables in from the sides or below; or used mini-trunking, or conduit (all options were discussed).
IP4X is only one of the alternatives for a top surface. IPXXD is the other and is far less onerous than the former.
