But the question is; Are the lugs of a breaker, designed to IEC standards, capable of directly accepting this type of conductor, or is a ferrule required?
Using lugs for termination
- Thread starter TMMB
- Start date
What type of breaker is it? UL-489, IEC 60898-1, 60947-2 or ?
IEC 60898-1 DIN rail breakers are used here they are often dual listed under UL-489, you can find them generally from manufacturers such as Siemens, ABB, Schneider, Eaton etc.
They typically allow stranded wire as mentioned above.
IEC 60898-1 breakers show nominal current is combined with the curve (for example 20 A breaker of C curve is marked C20).
Fault current breaking capacity is marked in Amperes in a rectangle e.g. 6000
IEC 60947-2 breakers are application specific so if the breakers is identified as on the side as a IEC 60947-2 or has the fault current capacity marked in kA, you need to consult the manufacturers documentation included in the self certification (CE) for the types and sizes of stranded wire allowed.

Personally I'd read the manufacturer's documentation

See post 12. This is not an NEC application.
The OP simply wants to know if an IEC breaker lug can handle standard IEC stranded building wire. UL listed breakers do, but what about IEC only breakers.
I agree with Joe, a quick look at any IEC manufacturer's data sheet is all that is needed.

A big electrical contractor from here in Hazleton won a bid for some kind of big project that if I remember right was in France. We had some mutual friends and they told me he lost a fortune on it because of it all being European standards. Big learning curve, slowed the job down. He was a smart guy, but that job was not so good.
Funny story about him is, he went someplace and had a Wendy's Frosty. He liked it so much that he bought a Wendy's franchise and opened the first one around here, Poor guy died in 2019 of Parkinson's. RIP
