Electrical shocks.

I have never been shocked by our household electricity. But I have heard stories about seeing in slow motion, and not being able to let go of the wires, and of course, death.

 

We have 230 V Alternate Current here between phase and neutral (the two holes you don't put your fingers into). That's double what people in the U.S. have. The frequency is 50 Hz, compared to the 60 Hz in the U.S.

 

Remember kids, 0.029 Amperes kill you. Most of your appliances are in the whole number Ampere range, meaning if you put yourself in series with your electrical device, it's game over. No joke!

 

 

I repair old telephones, and many of them have a hand crank generator, to generate the ringer sound (the bell). By cranking about 2 and a half revolutions per second, the electricity generated on the line is 35 Volts Alternate Current, and electric current of about 0.06 Amps, at 20 Hz. I have by mistake got zapped by that, and started crying. Yes, grown ups cry. Alternate Current is not only dangerous but also very painful.

 

I have also been zapped by electric fence a few times. That's 5000 Volts Direct Current for an short instance (with very little Ampere, so "safe electricity"), and it hurts badly. It doesn't make you cry, but it is enough to make you never want to get zapped again.

I got shocked by a laptop battery once. It left a really painful burn on one finger.

I've been shocked by 120 volt AC several times thanks to shoddy wiring in older houses/buildings. I always turn the breaker off, yet each time it happened, I got shocked by the neutral wire. :unamused:

Nowadays when a family member wants a ceiling fan or new light installed, I wear gloves and use a voltage detector pen. I don't trust anybody's wiring and 120 VAC hurts!

Also got shocked by 12volt DC one time. It happened while I was working on my truck. Like a dummy, I removed the positive cable from the battery while the engine was running and received a shock.  :dry:

When I was a kid I remember plugging in a night light and accidentally grazing the metal plug with my fingers. I got a very mild shock with no sparks or anything that wasn't even painful, it just felt like my fingers were vibrating.

Apart from that, I've only been shocked by the occasional bit of everyday static electricity. Really annoying.

I got zapped multiple times - 230V AC, ~300V DC (from a tube amp or a switching power supply I was working on), spark plug wire etc.

When I was a kid, I had a flyback transformer from a TV. I figured out that if I hold the output wire and connect 12V to the primary site I'd get a shock that felt like getting punched in the head (though getting zapped by a spark plug wire was more painful than this). So, naturally, the next time a friend was at my home I said "here, hold this" and proceeded to shock him :twismile:. Later I built a two transistor oscillator that I would use with that transformer to get nice arcs. The high voltage did not hurt directly (too high frequency), I could only feel when the arc would heat up the skin.

You should create a Youtube channel similar to Electroboom. That sounds so professional! :pistachio:

Unlike him and except that one time, I do not try to intentionally get zapped, I do not really like it when it happens :twismile:, just like touching a soldering iron on the wrong end - it happens once in a while, but is definitely not fun when it does.

I have worked with very dangerous stuff, as well as deadly things, but always with the right protection, so I have never gotten shocked. And to tell you the truth, I don't want to be fried, do I still protect myself

I got someone to shock me with a dog collar once.  Didn’t really hurt. 
 

My friend got me with a cattle prod once too.  
 

And I’ve touched an electric fence before. Felt like a hard, swift kick to the back.

I once participated in an Electrified Fence Barbwire Cage Match in my old backyard wrestling promotion. I bumped.

It's like, someone is grabbing your insides and shaking them all around, super uncomfortable, what a rush afterwards though!

I've gotten shocked by 120V AC plugs and light sockets just through the hand by accident when younger and it doesn't really "hurt" it just feels really weird/annoying and surprising. You wouldn't want it going through one hand and out the other as that could interrupt your heart and could kill you.

I've also been shocked by spark plug wires and THAT is actually painful.:blink:

 

Call me an idiot if you want, but I usually do wiring of household 120V stuff with the power on, unless the wiring is really packed together. :yay::ticking:

I test with a multi-meter to know what's live and I know what order things should be connected and when not to touch certain parts in the process once the ground is connected.

I'm just like, "F-IT, We'll DO IT LIVE!" :angry:  (+1 muffin to whoever knows what that's from.^_^) I haven't been shocked doing wiring that way yet.

the latest thing I did last month LIVE is updating the front door porch and entryway/landing area light switches in my parents house. It was just old flip toggle switches now updated to rocker switches, with the porch switch now upgraded to a Bluetooth remote/timer switch.

I used to work as an apprentice electrician way back in my teens. I dealt with plenty of things that should have given me electrical shocks, but due to the tools I used, I was always safe from any actual shocks. The only shock I had was finding the electrician I was supposed to be working with one day collapsed fast asleep in the back of the van after apparently coming to work after a heavy night of drinking. I didn't really learn anything from that guy. He was a bit of an unpleasant wanker if I'm being honest. Gave me a hard time.

Anyway. I always used insulated screwdrivers whenever I did any kind of wiring work. The most useful ones are the screwdrivers with the little light that lights up if a wire you are touching is live. I mean it was always common practice to switch off the supply to what you were working on, but there was always the hidden risk of unwanted surprises and those screwdrivers were awesome for avoiding said unpleasant surprises.

I sadly got my mom to touch a cow electric fence, because I made her go first. They are quite strong, took a minute for my poor mom to recover

Spoiler

They are not dangerous. There was no cows on the field, both of us thought it would be turned off

My middle school used to have push-button electric dryers in the bathrooms. I got shocked if I touched two of them at the same time.

My uncle got badly shocked twice while trying to repair an appliance. An unfortunately foolhardy thing to do for a guy who's had open-heart surgery! His excuse was that he couldn't find the right breaker on the fuse panel to turn off the appliance.

IF YOU DON'T KNOW WHICH FUSE IT IS, THEN JUST SHUT ALL OF THEM OFF!!!

What's the worst that could happen if you disconnect your entire house; you have to reset the clock on the microwave oven? Who cares!

Electricity is hazardous and should always be treated with great respect.

Have you ever thought about the fact that the potential energy inside your phone/laptop battery or PC power supply makes it comparable to a hand-grenade?

3 years ago I was in grandparent's house in summer, the signal there was non-existing with one H+ spot near the window. My phone's battery was dead so I grabbed an extension cord, it was hand-made with no bottom (my grandpa was electrician) and I had to hold it. After a while I drowned into my thoughts and started playing with the cord without realizing in, eventually I slipped my upper lip inside and boom! I felt instant shock that went through my head and my vision bursted with sparkles. It happened very fast and I wasn't injured, but it was quite... refreshing:sealed:

My dad once almost got killed back when he was in the Marines. He was repairing a radio communications system when someone turned the power back on. He told me that the only thing that saved him was that he fell over backwards and he was no longer touching the live equipment.

This one person told me, for whatever reason, they wanted to fix their LED lights on their walls at 2 in the morning. They wanted to reposition them, and they did so with their teeth. With the lights plugged in.

They were okay, but obviously they got shocked and the lights might have broken.
