The polarity on the small breaker indicates the flow of current,not actually the polarity of the wires. I.e ; + is positive input & - is positive output on the same direction

[@realToby]

Polarized DC breakers can be very tricky. If you connect it wrong, it can burn/catch fire. I understand the + or - is meant for the "supply/source" or "higher potential" only depending on which side of the breaker is connected to the supply. The load side should continue/match the supply. Only experienced people should use polarized breakers.

[@Moj_Energy]

there are different type of DC breaker, but positive and negative symbol is telling u something else not as u said (not cross entry or exit). it is telling u if source e.g PV enters from the top, obey this polarity, and. If entry (source PV) from from bottom obey this polarity. I have encountered this before so kindly do your research on things before writing things off or informing our people. Although polarized DC breaker is already going off fading out of market. and so many repacked AC breaker into DC breaker is a fact from you sir.

E be like Na you dey print am

[@Moj_Energy]

​​u said so oooo am not into breakers sales, but we cannot be Mr know it all but it is understandable anyway, I have learnt from your several videos very enlighten, I just felt on this I just have to let u know the information u were passing are total correct which pointed some out, I mean not harm so calm down. ​@@Mairigaemmanuel

[@oranusichigozie5219]

The first one you condemned is a DC breaker not an AC breaker based on the icon(MCB) miniature Circuit breakers & also the DC voltage icon noted on the body....but from your odeal, I will say its totally a fake MCb, I mean a fake MCB in the sense that it's an overated type of MCb without tripping ability: let me Explain why it's so: It's a dc Breaker but the Trip current is overated..(Note , trip current are different from rated current) to know the trip current for your breakers, check the C info labelled on your breaker, you can see figures like C30, C60 etc....For e.g C30 means once the current flow rises above 30amp, the breaker must trips off to protect your system.....let's not dive into the rated current for now......but in a nutshell, the rated current for a breaker is the maximum current the breaker can handle, meaning any current flow above the rated current of a breaker will lead to overheating thus burning and melting of therminals which can result into fire outbreak. For the fake DC breaker I mentioned,its like buying a Dc breaker rated at trip current C60 but cant carry current more than 30amp meaning buying DC breaker rated C60 but in reality u just bought C30 rated at 40amps breakers thus resulting to overheating and burning of terminals once current rises above 30amp which doesn't trip off to protect your system in any way leading to overheating once the current passed above 40amp as your MCb is normally rated, but in your mind....maybe your system was meant to allow maybe 45 to 50 amp on peak periods thinking you have C60 breakers which should be well within safe limit,but before u know it, it starts burning even when you know your cable are properly sized......The good original underrated ones will do you a favor by tripping off, that's why you see some people complaining about regular tripping off of their breakers 😅😂.... Many people are ignorant of this but it's well. The second one you referred to as more original is just an isolator...(Based on the icon as u showed them)...Thats not a breaker it's just an isolator professionally as the name is called......isolator is just a switch that disconnects both positive and Negative flow same time,They are mostly installed to separate a particular portion of your system incase of future maintenance, e.g......Between inverter and battery.....isolators doesn't trip, so far the rated max current is within range it works fine, but if u undersize them, you risk the possibility of overheating and burning of terminals once the max rated current is drawn through them.........Thats the Reason you see them as more original because at least you know how to size your system, thus choosing the Best rated ones for your design...if you want original breakers,I suggest u go for Chint breakers.....Look for any Chint direct dealers and buy from there ,you will have nothing to worry about(Talking from experience). There might be other good breakers but based on self assurrance, i dnt buy all these personal branded breaker products,most of them dont trip based on what They are rated for... This alone can pose a risk to ones installation, one might understand his installation design but failure to know or detect and differentiate breakers / isolators/ switches/ trip current / etc & rated current for these devices can pose a risk to ones effort. Information and knowledge is power and always will it be... .. We are all in this game together & we learn & improve as day goes buy... Over rated breakers, inability to different between breakers, switches, isolators , etc....can mess up ones ones installation work without knowing it

Isolator and breaker are same thing. They do same job

[@oranusichigozie5219]

@@Mairigaemmanuel ..... isolators dnt trip, that's what makes them different from MCB...... Isolators are manual trips, meaning you off them by yourselves JUST like switches..., But MCB trips off automatically on its own once the trip current is exceded Can they do the same Job?..... probably Yes....if only you size your isolators properly ...but that doesn't make them same in any way. Now let me further break it down intensively and here is why, MCB (Miniature Circuit Breaker): An MCB is designed to automatically trip or disconnect a circuit when it detects an overcurrent or short circuit, protecting the circuit from damage. Isolator: An isolator is a manual switch that is used to isolate a section of a circuit for maintenance or repair. It does not have the capability to detect faults or trip automatically. It is used to ensure that a circuit is completely de-energized so that it can be worked on safely. In summary, an MCB provides automatic protection, while an isolator is a manual switch used for safety purposes. Thanks u

[@BTW...]

@@Mairigaemmanuel They may both open the circuit, but the Isolator/Main Switch is nothing more than a switch. The circuit breaker is an Overload device, intended to self actuate a trip mode and act as a switch rated to the supply and load... be that AC or DC.

[@BTW...]

You have some wrong there, especially regarding 'rated current' or the assumption or a C60 no more than 30A. If this is a genuine LeGrande MCCB rated at 60A with a C trip curve (the C in C60) it will certainly carry 60A all day and night without terminal or mechanical burning... at AC or DC. No trip... no problem. The trip curve is the time delay on mechanical trip according to degree of transient overcurrent, like when a pre-loaded motor starts, lets say in a locked rotor condition which happens in compressors or large machines. You can buy those MCCB with different trip curves off the shelf.. .you can buy adjustable trip.. you can buy programable trip curve overload. You can buy shit fake stuff dumped on naive markets too. You seem to not understand the other Current rating marked on the case... maybe 6kA or 10kA domestic stuff. I'm accustom to working with 45kA and 100kA fault current rated gear. Some crap domestic switchgear is only 1.5kA. The 6,000A rating is only achieved when the device is used in accordance to manufacture's installation recommendations. It has nothing to do with resisting burn out at a maximum current. It has to do with safely containing a prospective fault current. Here is the thing though.. the most important thing is buy DC switchgear, designed to quench the arc generated between switch contacts when they open under a high current load. There is little difference between an AC and DC MCCB internally (and externally obviously because the are in a standard DIN 35 case style). The ONLY difference is additional arc quench to ensure the device isn't a flaming plasma ball. AC arc suppression is easy and simple.. not so DC.

can't see the symbol on it

[@venuskratos6311]

Can you make review about opti solar hybrid inverters?

[@pejuakinwande1166]

Thanks always.

[@olayinkaolatunde3028]

Both breakers you have don't look like genuine Schneider products. Schneider has official distributors in Nigeria and I'll advice you obtain original breakers from them.

[@larinka1736]

Bro, God bless you. The smaller one I got burnt at 28amps, e shock me. I am still looking for a better one. Please, which one do you suggest?

[@Mairigaemmanuel]

Get chint

[@BTW...]

Don't take the word of this guy, that demonstrates a profound lack of knowledge, as being credible or worthy opinion. The appropriate devise should be designed for DC use, not AC. And, sized for the load and installation method, in accordance to the manufacture. Better get someone who knows what they are doing rather than meddle with such equipment yourself, because clearly you don't know too.

[@Mairigaemmanuel]

@BTW... 😂😂😂, oga I too know well done o. As a human you can't know everything she

[@okparamichael1690]

Which Dc breaker you will prefer us to use eventually

[@Mairigaemmanuel]

Chint

[@abelobiora1079]

I have 2 charge controllers connected to the breakers one of them always trips off I don't know why P.s mine looks like the type on the right

[@julius-jayboy1]

Hehehe na so Jonny take burn charge controller because of these polarities for breakers, God save am, I help am fix the charge controller.

[@Mairigaemmanuel]

Ahh, that is why I always use my digital multimeter to confirm before doing anything on breakera

[@annebokma4637]

Just for info it is this breaker or these breakers.

[@Mairigaemmanuel]

[@samisaac3908]

Please could you help solve this puzzle between Jinko Panels and Africell Panels, what are the differences between these panels and which panel will you recommend and why?

[@Mairigaemmanuel]

Go for jinko if know where to get the real jinkos. They're tier one

[@abdulsalamabdulrahmanabayo2189]

both are great panels. i have used africell and i can say it is top notch

[@FrankAmaizu]

From my experience, this is Spot on right. That big one is more of a DC Breaker than the small one, it's more of an original AC breaker😅

[@Mairigaemmanuel]

😂😂😂, same thing here
