The exam in question is the final practical im assuming. It will entail a full installation from a consumer unit with 4 circuits. Radial, RFC with spur feeding a fcu, 2 way lighting and s.w.a into a commando 16 amp socket. There will be pvc conduit used on the rig and steel conduit plus metal cable tray all of which has to be fabricated, bent and threaded as required and terminated into appropriate accessories like metal clad surface mounted 2 gang sockets. Plastic conduit boxes for the lighting circuits with pvc conduit. All circuits we wired were wired in singles using the appropriate sizes for the circuits. Easily done in allotted timescale and all of which you should of learnt over the previous wiring modules during the year.
Your test rig will be inspected and tested dead and then you will be taught if the tutor passes the rig the live testing process.
Good luck and dont rush it is my advice tutors are there to help you and try and keep it all neat and tidy looking i.e all accessories straight and conduit runs straight and neat.
