Running 3 phase and single phase links from a single RCD

It is possible to supply the single-phase loads through a three-phase RCD. This would simplify
the arrangement a good deal, however it is not recommended to supply a mixture of single and
three-phase loads through one RCD. The reasons for this are beyond the scope of Phase 2 of the
apprenticeship.
That doesn't really mean anything does it? Lots of things are possible.

Perhaps when they achieve Phase 3 of the apprenticeship it will be allowed.

It would appear that the linked to document is talking about a particular installation i.e. a test bay in a College or similar over in Ireland. It could quite easily be just an opinion of a college lecturer.
Indeed - and, to be fair, all it says is "not recommended", not "not allowed", even if we're not even sure why it's not being 'recommended'!

Kind Regards, John

Indeed so - and not just 'possible' but, IMHO, probably perfectly reasonable in the OP's situation.

Maybe :)

FWIW, I don't see any real point in/need for you to change anything.
Thank you, I 'll leave it all well alone. It just goes to prove how misleading online articles can be if you don't really understand the subject matter!
You're welcome, but I don't think you should just take my word for it - see what a few others say as well - for all you know, I may be just as misleading as those online articles!!

Kind Regards, John
