Parallel circuit/supply needs all conductors to be of the same CSA, follow the same route, cables be of the same type and construction. Parallel circuits can consist of several conductors/cables not just two. Such circuits can and do offer many advantages over a single much larger conductor/cable installation....

If designing the OP's circuit from scratch probably 2 X 16mm would be selected, but in some circumstances even 2 x 10mm could replace a single 35mm cable....

 

[telectrix]

so, in a nutcase, sorry, nutshell, as OP already has a single 25mm, the solution is to parallel a second 25mm cable in.

Don't spoil it prematurely Tel

i already said it in post #6.

Hahaha!! We remember the previous thread well!
Find the link to it...

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...

Ah, the saga of applying a grouping factor to a single circuit, i remember that farce well!! lol!!

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

so do I, now...

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.
