I am finishing up my NAPIT LCL training, got all of my modules, 18th edition and I+T all done- heading out to support another sparky as a freshly retrained 53 year old. Just doing the final design assignment to finish up the course, which involves a virtual garage extension to a house, built in rendered blockwork. I have to spec out the whole job, which is mostly doable but had one query - running sockets to interior of garage, the notes don't mention whether blocks are lightweight or solid concrete- in the real world I'm guessing they'd more commonly be the lightweight variety.
Either way, I can either run cable in conduit, or chase into the blockwork - if I run on surface of blocks in conduit I presume I have to use surface mount switches/ sockets, I don't believe that there is an elegant / mechanically solid/ regulation friendly way to transition from surface mounted conduit into back boxes? If so I've not come across it in my own limited practical experince flying solo.
If I chase into the walls, I'll just use female glands into back boxes which is fine- however, as this wall is not going to be plastered then any covering over would have to be done with flat PVC cable cover which will remain visible - is this considered orthodox? I've tended only to use that to cover over cable which is going to be covered in drylining/ skim.
My initial instict was to use oval / round conduit into surface mount boxes, but because of washing machine / tumble dryer fridge proposed for garage, a little blub in my head suggested flush mounting sockets might be a better plan.
Any thoughts would be gratefully taken on board.
