I agree with the above but the question was "Does EN60065 permit fusing in
both line and
neutral?".

Generally, it is permitted (at least to most IEC/EN Standards) if the
fuseholders are the shockproof/shock safe types - for the reasons I
explained previously.

It is REQUIRED for many items of medical equipment to 60601 standards

Chris,

I do not believe that this kind of fusing is permitted if the fuses are
"user accessible". But as I remember from my previous life, fusing of
neutral is permitted in Class I equipment if a suitable warning (for
example "double pole/neutral fusing") is provided to a service person.
