It will either instantly trip the breaker or do absolutely nothing, depending on how it’s wired internally.
The real danger comes from when only one end is plugged in, though. With only one end plugged in, the other end becomes a 120V cattle prod.

billwashere@lemmy.world 1 day agoIf I’m not mistaken plugging this in to the same outlet won’t do anything. And as far as back feed problems couldn’t you just shut off the the main breaker, i.e. where the power comes into the house?

They’re illegal and it’s only safe IF the home owner remembers to turn off Mains.

There are legal ones for generators (especially small scale solar stuff) that turn off automatically when they detect no main power on the line, so grid workers can’t get zapped. They are pretty common around here.

Those are called Interconnects, use “Inlets” to hook them up and are not illegal. The suicide cable with two male ends can electrocute the owner and the line workers.

People usually want them so they can run Christmas lights the wrong way, either because theyve already strung them up backwards or they’re too dumb to figure out a better solution, but the end result if one end is left unplugged is an enormous amount of power just running loose at the exposed end. Even if you just wanted to plug it into the same outlet as a joke, if you plugged one end and touched the prongs on the other end while in the process of plugging the other side in, you’re pretty fucked.
