Good Morning,
Be certain that the cords involved are "Listed" or "Certified" before
going too far out of your way to track these "failures" down (Of course
Listed/Certified cords these can exhibit problems too, but to a smaller
degree).
I can offer, from personal experience, that appliance-inlet cords that
don't bear "markings", are often inferior products. I have purchased
replacement cords at computer flea-markets, which are made in China, bear
no markings (determined upon arrival at home), and which fall out of the
IEC-320 appliance inlets they are supposed to mate with (high resistance
connections = high I-squared R = heat !!!). Others, purchased at similar
venues which bear "markings" do not exhibit this phenomenon.
