Nothing like touching bare metal of something that is sending current to the wrong places.

He got the rubber sandals on. He is a pro after all.

Nvm, my guy is bare footed. He got the rubber stickers on his feet though I’m sure.

He's got his lucky undies on

He stayed at a holiday inn Express last night

Safety sandals never fail

He's barefoot.

He had them in his mind and it's the thought that counts

Let's not judge him too quickly. He might have some kind of Livestrong bracelet on.

This man is definitely barefoot.

the electricity can't go in your body because it is too busy making sparks

If I'm testing returned shit it's electrician's glove time for at least one of my hands. I've become a bit attached to my heart working correctly over the years.

Also, pro tip: If you are ever going to touch something that might shock you, never use both hands.

With only one hand, the current either loops through that hand or through your hand and down through your foot. With two hands, it goes in one hand, through your torso, and out the other. Much more likely to get your heart.

And use the back of your hand so you won't grab it.

That's what the ground wire and gfci is for.

u/Danternas 13h ago

I wouldn't trust ground, GFIC or the fuse for the matter after seeing the fiery result of the video.

I’m so glad both of these this also went through my head and yall said them. Feeling validated.

That’s not bare metal, it’s painted. It’s not conductive.

Take a multimeter, set it to ohms and measure the resistance between any 2 points on the chassis.

If it's less than 5kiloohm then congratulations, if you have a bad ground and the 230V wire is touching the PSU case, then congratulations, you're about to see if your heart knows how to restart itself.

u/JigglyWiggly_ 22h ago

Try it yourself first. I'm sure you'd also find it surprising that an anodized layer isn't conductive either. However in this case the metal casing is almost never anodized and painted instead.

u/Danternas 13h ago

Your skin isn't "conductive" either.

u/JigglyWiggly_ 13h ago

You can get numbers around 1meg through skin. You will read an open load trying to measure through paint.

Note that's resistance, as soon as you increase the frequency your impedance will drop noticeably due to parasitics.

u/Danternas 13h ago

And you can absolutely get electrocuted by anodised or painted metal.

u/JigglyWiggly_ 12h ago

What’s the conducting path exactly? Even a few microns thick is enough for it to become a sufficient insulator. 

Should you trust it? Of course not, it can be scratched off. 

I’m sure you will also be amazed to learn copper to copper clearances in a PCB can be sub 3 mil. No special stack up needed for that on a modern fab house.

Just go ahead and test it in practice if you're that confident.
