Are aftermarket power cords required to be UL / CE approved?

I fear your warning to mc might be a little bit too late. 🤭

Pretty sure all consumer electrics have to be by law.

Erichsch- you better check your info again.  If you install a wood stove and don’t get it inspected for example, insurance won’t cover a fire that was caused by the wood stove. If you had an electrician put in a 14 gauge wire with a 20 amp breaker and don’t get it inspected, insurance won’t cover a fire that was caused by that. I have asked these 2 questions to a few insurance agents and that’s the reply I got. I was involved in a 200 house fire 40 years ago and went thru the mess of getting insurance to pay for things. Ever since then, anything I wanted to add to an existing house like wood stove, dedicated lines, etc.. I always asked if insurance would cover the modification

There are Christmas tree lights UL listed... and the chances of your house catching fire from them is much much higher than an aftermarket power cord on your CD player.

I am almost certain that power cords must be UL listed if they are packaged with the equipment they power.

IF anything was to go wrong and cause a fire, your insurance company could reject the payment since they are always looking for any microscopic excuse not to pay.

Not worth it...  pay a few extra bucks and sleep better at night or when you go on a vacation.
