Electrical Shock Risks

Discussions center on the dangers of electrocution from household voltages like 120V and 240V, including personal experiences, debates on voltage vs. current lethality, and safety concerns around power surges and high-power circuits.

There's no electrocution risk with that?

Sounds dangerous. What if there’s a power surge?

I'm not necessarily talking about getting shocked (which can still end up being bad), I'm also referring to the fact a lot of those 120V circuits are probably only protected by something like 12-15-20A of circuit breakers that might take a while to actually blow and unless you're in a kitchen or a bathroom or whatever probably don't have GFCI protection. Messing something up can quickly lead to quite a fire.

It’s generally not a good idea to close a high power, high voltage circuit with a live human.

Only electrocutes 5% of the time. What me worry?

More likely to get electrocuted while trying to plug it in if you ask me.

Its not the volts that will kill you, its the amps

i got electrocuted by 240v ac 50hz more times than i like to admit. turns out its easy to disconnect, never held it more than 2s and its relatively painless.never went near dc hv stuff with isolation so never got a chock from that yet. i intend to keep it that way

Voltage does matter. If you have thick skin or touch cable through something (like layer of paint) it might be enough to save you if the voltage is 100V but not if it's 240V.

Getting shocked is a symptom of faulty electrics, not of using 230V (even in a high humidity environment).
