AFAIK, that requirement does not apply if a correctly fused appliance inlet is used because that should allow smaller gauge wiring from its outlet terminals – and that is quite common (or at least it was) for 60950 equipment.
Whilst I am here, I would suggest that because the appropriate UL Recognized wiring generally meets all the same technical requirements (as far as this standard is concerned) that apply for non-US certifications, I would always advocate that it is used where the equipment is going to be widely certified and sold around the World. It is a GOOD IDEA to use UL-Recognized wiring even if you sell mainly outside N.America but eventually want to enter that market, as otherwise it would mean re-specing all the wire in the equipment to get through the relevant certifications/Listings (unless you want to get involved in paying a lot of upfront and on-going fees to the Listing Agency to use something else – from bitter personal experience with equipment which was “dropped on me”, that is NOT a good idea!)

Also be aware that there is a minimum wire gage size for the incoming mains wire inside the equipment.

Try the US National Electric Code table 310-17 for single conductor insulated wire in free air at 30ºC ambient (hook up wire). Keep in mind that you have to de-rate the values in this chart for bundling (NEC table 310-15-(b)(2)(a)) and temperatures (NEC table 690-31(c))above 30ºC.

Looking for requirements for single insulated wires (UL, IEC, etc.) used inside an IEC60950-1 product (230VAC).
Any tips where I should start looking?
B.regards
