unsure about homework

[Baker1988]

Hi all i have been given homework from college and i am not sure about it, i have poseted on the general forum about this homework it is actually a practical in the workshop but i have been told to do a wiring and circuit diagram for the task

this is what we are starting with

and this is a rough drawing of what it is suppose to be a finish product

i have to start from isolator under the 3 phase board that my tutor has said "ASSUME" it is fead by a 3 phase balanced motor (no neutral) which is then going into the 3 phase board then from the 3 phase board i have to feed 2 single phase boards and 2 isolators, i have never done any thing like this before only single phase stuff and my wiring and circuit diagrams are total guess's so i just wanted a bit of advice if my diagrams are totally wrong or not
this is my wiring diagram (it is a rough drawing so sorry if you cant understand it properly)

it is a photo so sorry for the clarity.
this is the circuit diagram i have done
