Thank you Logan, glad it was helpful. South Africa is advancing quickly in renewable energy with our national grid failures. Chinese companies have so many specialists in DC Products, we used to get products from European countries, but they themselves manufacture there and just OEM their brands. Its my passion to dig deep into solar energy and share my experience and quality products. If you have TikTok follow me there on @johanmoesh I dont put all videos on UA-cam. Will in the future create more on UA-cam
These polarized breakers are confusing and dangerous..
Thanks for this video
Great pleasure
What about those breakers with indications as "line" on the top and "load" on the bottom. Are they also polarized breakers?
It is very difficult to say on most brands, but use a washer, if it has magnet inside it is polarity breaker. Search and seek manufacturers specs. I want to say if they don't have + and - marking on the terminal screws it mostly would be Non-Polarity MCB
Are all mccb's non polarized?
All, don't think so, but make sure from manufacturers, don't trust distributors. Most don't even know the difference
Why do polarized breakers even exist? Is there any advantage of a polarized breaker over a non polarized breaker?
They are cheaper, if used correctly they do the job, but it is very confusing for lots of people, installers etc.
The problem will be human error, lots of it in South Africa,
