I want to thank you for the videos you make. Heating and cooking direct from solar could be life savers for many, but not many watch your videos. The Oscilloscope that you had discount codes for I was able to get it for $45 and I would not have gotten it without your video. I am on a fixed income and the low price allowed me to get it. Again thank you for sharing your knowledge.
@JR-xw5dk Hi, you are most welcome, thanks a lot for your kind feedback. I do wish more people could watch these videos. PS fantastic deal on the scope, I think it will serve well. Thanks for watching commenting and supporting the channel!
Thank you for your thoughts. Although I think it is correct that the difference between AC and DC breakers is tge arc suppression, it does not seem correct to me to compare a DCs tendency to arc to a water hammer. The water hammer suddenly increases water pressure far beyond the static pressure by means of inertia. In case of electricity the moving mass and the electrons speed is too low to cause such an effect in everyday application. I think. DC does create arcs because the voltage that creates the arc in the first place, remains constant and keeps feeding the arc. In AC - as you stated - the voltage drops to zero 50 or 60 times a second thus interuptimg the arc. By the time the voltage builds up again the breaker should have physically opened up a gap that is to wide for another arc to form.
@solaroweder3707 It's not technically correct to compare electricity to water, but I do it anyway as it's helped me a lot with thinking through this stuff. Funny enough, I don't believe half the "electrical models" taught are even correct to begin with, but definitely better than nothing. A user of Conventional Current here :)
@simonmeyerjorgensen Not all DC breakers are polarized ruclips.net/video/44mJdg6fYJg/видео.html I plan to do more detailed videos on PV breakers in the future as soon as humanly possible
Do I need a breaker between the solar panels and charge controller? Its only 2 600w panels in series each is 47 open circuit voltage ,max power current 15. thank you for your channel.
@matmat7676 Hello, you are welcome! A breaker between the solar panels and charge controller is recommended for 1) fault over current protection and 2) a convenient shut off for service and maintenance. Hope that helps!

Thank you, I relate this back to welders that have AC or DC to weld with. Your expiation make complete since to me.
@57monoshock Welcome!!
Thanks. Beginner here. Always wondered about AC versus DC breakers

Why is there no sign where to put positive and negative? doesn't that matter? How to read the little diagram on it? Plz make a video about it

a lot of those dc breakers dont break the arc and go on fire
@samfish6938 Not good! Hope mine don't do that...
Only buy UL listed DC breakers
