> a single IEC C5/C6 coupler (the IEC standard is up to 2.5A but the UL certifies it up to 13A but still, the NEMA connector is 15A)
The UL missed the point of C5/C6 entirely. Yes, the contacts are totally fine for that kind of current. But the point of having it with C13/C14 next to it is that because C5/C6 is only rated for 2.5 A you can use thinner coper in the cables. Meanwhile all compliant C13 cables have to use a 1.5 mm² cross section to carry the full continuous 10 A load current. If this is correct, then a "fine according to UL" load would actually melt most C5 cables (generally 3x0.75 mm²).
