What's going on my friends this is Dustin Stelzer with Electrician U and today we're going to talk about different VOLTAGE SYSTEMS Alright so when I was an apprentice I always wondered, like, what is the whole 120-240-208-277v how do all of these numbers matter and where do we get them from so starting out you're gonna come across like a lot of low voltages you're gonna come across some medium voltages and then there's higher voltages now as electricians we call them low medium and high or we say line voltage but really high voltage is talking about like five hundred thousand volts and as an electrician you're never gonna come across that stuff so just for what we run into in the field typically we're talking about stuff under 1,000-volts and usually above 50-volts unless you're talking about low voltage systems you know we're talking like 5-volts 10-volts 15-volts 24-volts stuff like
