One of my first jobs when let loose on the plants as an apprentice was running 10 parallel and 2 triple feeds. All 185mm² PILCSWA.

I’ve been using parallel feeds ever since they make sense to me. The cable gangs didn’t complain either.

It was a bit frustrating for me as no one was giving me an answer to my question. It was only until post 129 that things became more clear.
I would like to thank Eng54 for bearing with me on that thread and also Rockingit. (Also everyone else who helped me)
I always want to learn new things but being an engineer I need to know why things work as they do and sometimes this needs to be explained to me in layman's terms...

good debate though.
and i agree with your assessment of applying grouping only to seperate circuits not multi-feeds of 1 supply

Digressing back to the OP query and against the general opinion of the responses.... yes you can have parallel cable runs of differing size cables of the same supply but certain measures and extra protection is required but with regards to the OP trying to save a penny or too and for the majority of these set-ups then no you wouldn't have variable size cables withing the same parallel system.
