Nice vid. Question: is it standard that a full charge of the spring allows OCO or can it just be one or two operations (OC or O/C alone)? Keep up the good work! Cheers.
Thanks for your question Vilayattu. The physical size of the current carrying contacts make it difficult to operate manually as you would with a molded case breaker. In addition, the springs allow for a quicker trip, allowing the breaker to clear any fault. Thanks again. Please subscribe to my channel as I will be adding more electrical training videos.

Thanks Azeem for your comment. To my knowledge a full charge allows OCO. After a OC the spring could be recharged.
