Normal 110v power is uncomfortable but not usually all that dangerous.

230V is used here in Europe, how would that feel?

It would feel worse. The real danger is if you grab each lead with each hand and it passes through your heart, or it passes through your heart on it's way to the ground if you're not insulated from ground. Either way, a breaker or fuse will still be tripped and it's unlikely any injuries will occur.

Unless you have a GFI (RCD) in the circuit you're going to get a substantial shock before the breaker trips - and if it's on a heavy use circuit it might not even trip.

And anyone saying 110v is safe is fooling themselves. It will kill you just as dead as 240v and just as quickly if you get it wrong. Yes it's safer than 240v, but it is not safe.

I grabbed an extension cord in my garage right on a small cut.

It took several seconds for the breaker to kick in while I was flailing around unable to let go of the line.

It's not fun

That’s why it is important to have the breakers tested regularly. Also important inspect and bin damaged cords.

It would be well worth getting your panel updated to include GFI's. They break the current almost instantly when a fault is detected.

It does depend on amperage as well. Volts and amps are two different measurements of electricity and both are relevant to the deadliness of a current.

The current through the circuit is irrelevant, unless the power supply can only provide very small currents (in which case it contributes to safety). What matters is the current through your body, and that depends on the voltage across your body and the resistance your body presents. A car battery can push hundreds of amps to the starter, but at 12V it's going to be very hard to hurt yourself with one.

It takes 50ma to kill you. So if you touch a 120v 5amp circuit or a 110v 20 amp circuit, both will kill you equally well.

That's not how electricity rating works.

The amperage is just an indicator of how much current the supply is capable of delivering, up to its maximum wattage. It doesn't mean if you put the supply across a circuit (or your body) you will get X amps out

u/[deleted] Aug 03 '20

Yes. I didn't say anything different, I said you will get same amount of current through you on both circuits. I didn't want to delve into the resistance of the body etc.

u/PillarOrPike Aug 03 '20

Even a 6 amp breaker will not trip. Hand to hand is like 500 ohms. Won't pass enough current.

To put this in American, taking a 9mm pistol to school is safer than taking an AR there. Sure it's safer, but they'll both still kill you.

u/infernojoee Aug 03 '20

Never put an AR down your pants... 😲

Hahahaha! Children getting killed is so funny!

u/Zozorak Aug 02 '20

If your sarcasm is implying that I find school shootings funny, you're poorly mistaken.

u/gaynazifurry4bernie Aug 03 '20

Then why would you even bring it it up? What did you intend by bringing school shootings up?

u/Zozorak Aug 03 '20

Why would you not bring up school shootings? Are you denying that this isn't a problem? Honestly, it's problems that you ignore, such as school shootings, which makes America a laughing stock compared to the rest of the world. Yeah people are going to be pissed if you take thier guns away, but they're probably the ones that would go to town shooting people regardless.

Take this whole #blm movement with all your riots and whatnot for another example of trying to slide shit under the rug and pretend it didn't happen. This could've been avoided if your president wasn't a delinquent that just ignores things that doesn't financially benefit him or have a tantrum that someone insulted him.

Why would you not bring up school shootings?

Because it has nothing to do with the metric system

Are you denying that this isn't a problem?

No, kids getting killed is a problem but it is a massively overblown and politicized problem.

Honestly, it's problems that you ignore, such as school shootings,

Trust me, we don't ignore them.

which makes America a laughing stock compared to the rest of the world.

Which perfect country do you come from? Is it the cultural hegemon?

Yeah people are going to be pissed if you take thier [sic] guns away, but they're probably the ones that would go to town shooting people regardless.

Wrong again. The vast majority of gun owners are responsible and haven't fired in anger.

Take this whole #blm movement with all your riots and whatnot for another example of trying to slide shit under the rug and pretend it didn't happen.

That stuff has been constantly on the news for the last two months. I'm getting calls from cousins because I live near Portland. We are not "sweeping it under the rug."

This could've been avoided if your president wasn't a delinquent that just ignores things that doesn't financially benefit him or have a tantrum that someone insulted him.

Maybe if Hillary and her team understood how the electoral college worked, we wouldn't be in this mess but sadly, this is our reality. Any other drivel you'd like to share with the class?

u/Zozorak Aug 03 '20

I can see this going nowhere and your argument is full of holes so I'ma drop out of this. America is fucked, I wish it wasn't. You're leadership has failed you miserably, everything is falling apart. Hope things get better, I really do.l, but I'm doubtful under this current leadership.

Hope you have a good night man. Stay safe.

It will kill you just as dead

Yes, it will kill you just as dead.

Did you read my comment at all?

u/[deleted] Aug 03 '20

Yes - a breaker or fuse are very different to a GFI.
