    What voltage is dangerous?


    What voltage is dangerous or/and deadly? How can I safely tell what voltage an appliance or other electrical item has? Is this something I can even do myself?

    "Any Voltage can be dangerous it really depends on what you're trying to do. You can do it yourself there are good voltage testers you can buy but once again if you don't know what you're doing I would get a professional to do it for you, or at least more info needed as to what you are trying to achieve."

    "All voltages are dangerous
    Any amount can kill
    Items that are SELV or safe extra-low voltage
    Are the safest but still need careful handling"

    "The appliance in your house has a nominal voltage of 230 Volts. They can be dangerous if faulty and not adequately protected with an automatic disconnection device. However, things like a mobile phone have a transformer which reduces the voltage to below 50 volts. I do not recommend you touch any live wire irrespective of its voltage."

    "In industry, 30 volts is generally considered to be a conservative threshold value for dangerous voltage. The cautious person should regard any voltage above 30 volts as threatening, not relying on normal body resistance for protection against shock.
    But the voltage going to your appliance if in any domestic dwelling would be 230volts ac as standard you could test this at the live and earth connection inside the appliance with a multimeter if it is any lover that 220v there is probably a fault in the supply."
