It was always considered good practice to keep at least 6

Isn't there a requirement for a warning sign if this is not the

I've not done any three phase since the latest regs came in, so I'm not up
on them, but there never used to be. The requirement was for a warning sign
where two or more phases are present inside equipment that might normally be
expected to be single phase, such as light switch banks.
