It goes like this, on the the 25th, a minor shock? No, a mortal shift...

I know even less probably but I'm going to say yes and let you find out for me.

Reversing polarity is a Starfleet-approved procedure in all situations.

It's not that it won't work - polarity doesn't quite work like that in AC systems - it's that as soon as you plug in one end, the other end has a pair of exposed metal contacts with mains voltage between them. One mistake, touching the contacts or having them come into something metal (like the ladder you are using to hang the Christmas lights) and someone dies

in AC, which is what home electricity uses, the polarity is constantly switching, from + , then - , then + , and so on, 50 or 60 times a second depending on where you live. This means that, unlike batteries, it's symmetrical, and you can just splice the cables and attach two male plugs together and they will work regardless, even if you somehow attach the neutral to live and live to neutral, in fact in many countries you can actually buy just the plug without the cable and then you can assemble it yourself in whatever way you please.

of course tho, this should be done only if you have a decent understanding of electricity, and it should not be attempted by someone who lacks those competences, hence why hardware stores "gatekeep" male to male plugs. If you really need one and are sure you understand how they work, you can probably make one yourself.

Teehee, it tingles!

Strand of exterior lights, one end male plug one female. Idiots start to mount the lights with the female end near their outlet. Get done, become confused, go to store for male to male cord to plug into female end.

The female end is for chaining multiple strands, not for supplying power (directly) from the power socket.

Their lights usually have a plug on one end and a socket on the other. Ppl put them around the exterior of their hoses, then realise they did it the wrong way, and the socket end is near the outlet they wanted to plug them in.

Or they mounted two strands of lights, and where they meet up it’s either 2 plugs or two sockets accidentally.

I thought that was a snake....

aaaaaahhhhhhhhhhh lic-

I too have developed into a very politically correct person with lemmy, I kinda miss being able to make gay jokes

How do you non-sketchily feed a generator's power into your home?

Modern inverters do this somewhat safely by sensing the phase before outputting power.

Of course, you can’t tell just by looking, so I still would steer clear of the whole thing on principle.
