You sure that's speaker wire and not transparent-insulation lamp cord? The stuff does exist.
I have some things fitted with cord like that -- usually it's lamps.
Me too, I have a US table lamp with translucent SPT1 zip cord. I guess if the opener weren't plug connected but hard wired this would be ok in some countries - the load limits the current, removing the need for OC protection. Short circuit protection is provided by the 20amp breaker.
Anyway, with that creative trailing socket it's illegal.
