    Worth noting that a lot of DC MCBs have magnetic arc suppression where a magnet directs the arc into the suppression chamber. These breakers have + and - indicated on the terminals and the polarity should match the source of fault current.

    There are still many polarised breakers around with magnets to move the spark into the extinguishing champer. If they are connected with wrong polarisation they catch on fire. The flow of current must be correct from + to -. If the source comes from bellow into double breakers, the + must be connected to the side where a - symbol is printed on top of the breaker shematic.

    Great vid, good info & content, thanks for this tutorial. Another commenter asked about what type of breaker switch is best advised between an All In One system and the battery, as either side becomes a source between charging and discharging events. I have 48v & 24v AIO systems I am implementing for different projects, (bus, shed, house), so this should be a dual pole 150A-250A ‘NO ARK’ type DC switch I am guessing for 10kw-15kw lifepo4 battery bank, does this sound about right? Cheers

    I appreciate this great illustration. My confusion occurs with (NEC-type) Safety Regs for DC circuits. Circuit Breakers have the arc extinguishing chambers, as I understand, while I have read that Isolator (rotary) Switches do Not. Yet, NEC codes require Isolator Switches for DC arrays. So … for a Small (2 panel) system, is it Best practice to have Fuses between panel & MPPT, plus Isolator, plus Breaker … or which combination thereof, or only one …. ? I have also read that as long as the current specs of my panel is BELOW my MPPT, I really don’t need (any) ….. now it should seem Clear how easily one can become Confused …. 🤷🏻‍♂️

    Hi - the video on explanation of how the DC and AC MB'Cs function is great - however - the speaker does "NOT" mention the consequences of arcing - the breaker, be it small in size or larger ACB's - one cannot operate the breaker beyond the contact rating as a result of ongoing tripping. If a any breaker has exceeded the contact capability, the breaker under fault conditions will explode - he does not mention this - very confusing as opening/closing/opening etc. under specific fault levels will cause the MCB/ACB to explode. This is where a "ductor" test should be conducted - this checks the condition of the contacts. The breaker would inevitably fail after several trips - this is a short comment to a much longer discussion. Thank you. Richard Murphy (Pr Eng)

    Very Good & Thank you ! I’m a DIYer attempting to design and implicate Battery Back up for if and when the grid goes down which it does every few years where I live . My breaker box is a normal 1 - 120v @ 100A 20 or so Circuit breakers & I’ve only got 1 - 220v Circuit my central AC what shift the grid goes down we’re not using central AC we could use fans That’s not the point my Inverta is a 5 kVA 230v charge controller 48v my battery banks are 15 pease 3.2v 280Ah lithium phosphate Daily 15s 120A BMS & 20 peace 2.3v 40Ah ithium titanate batteries ANT 20s 100A BMS “ my Inverta 230 V would like to used to hotline which is 115 V the neutral line is 115 V all still single phase can I put on a 230 V single into a double pole breaker both the L one hotline 115 V and the neutral which is 115 V to make my breaker box single phase at 115 V for a battery back up if the grid goes down and I have the solar inverter that can slowly charge by Lithia batteries very slowly ! So what I want to do run both powerlines to a double pole breaker both the hotline in the neutral because each are 115 V in the ground would be to an earth ground but then what would I use for a neutral if I’m using the neutral as a hotline but then what do you use when you use in a 230 V for a neutral because there is no neutral you just have two hotlines & a ground ? I would greatly appreciate in your convenience if you could just jot down your ideas and your wisdom !

    I believe the circuit breaker is shown upside down. If you turn it around so the arc extinguisher is at top it makes more sense. The hot arc travels up (hot air) and such the extinguisher does its job. Having it on the bottom completely negates its presence.

I understand some DC breaker are direction sensitive (eg. if top side is source then bottom is load or vice versa)... my question is when I try to connect my hybrid inverter to the battery, which side is source and which is load.?? Because if the solar charging is active then my Inverter is the source and my battery is load, and if the inverter is active then my battery is the source and my inverter is load.. Thanks...
