Dear Sir, Thank you very much for your comments and suggestions. You will notice I have brought the VCB separately from the complete power unit. When I work inside the electrical substation I shut off the electrical lines and must use safety. I give utmost importance to safety while working in electrical substation. Gloves must be worn while working inside electrical substations. We also have some other safeties that we maintain and handle on electrical lines.

We use MCB at home. See it as a home appliance. But MCB is updated by ACB, ACB is updated by VCB. So I look at VCB as a home appliance and made a post about it. Of course your rules are correct. But according to your rules it will be a home appliance of electric low voltage line. I also understand that you want to prioritize electronics.

I will definitely follow your rules and create the next post. But knowing how to repair VCB is very important for an electrician so shared the post.
