That cable is too thin for 16A
Doesn't look like 'just' 10mA to me :-(

Supposedly 0.5mm² of copper
Hmmmm.
Each wire has about 20 strands. Diameter 80µm. There's just NO WAY that adds up to 0.5mm². Depending on how I calculate the cross section (multiply strand cross section vs. measure wire diameter with air gaps), I end up with values between 0.005mm² and 0.15mm² - NOT ENOUGH.
