How to calculate the general circuit breaker of the QDC and installation loads: • How to CALCULATE GENERAL CIRCUIT BREAKER PANEL ... Every electrical installation needs a place for the entry of the electrical network of the energy distribution company, this place is called the installation's entry standard, the term standard is because it is really a standard that each energy concessionaire establishes, so we cannot do it in any way, but then, how to size the electrical installation's entry standard? In Brazil, there are several electricity distribution companies and each company establishes a type of supply and voltage levels for the electrical installations, so we must consult the electrical distribution concessionaire of the region where this installation will be made. Normally, on the companies' own website, we can already download the manuals, standards and procedures for sizing and installing the installation's entry standard. But basically we will need to know what the total installed load of the installation is to determine the type of supply and the voltage level of this network, and we will also need to know what the maximum demand current of this installation is to determine the standard circuit breaker, in addition to the input cables, grounding cable and cable input conduit. All of these procedures for sizing the installation's input standard are in the concessionaires' manuals and we must follow these procedures to avoid failure when installing the electrical network, especially in relation to the standard circuit breaker and the electrical installation's input cables. So, let's learn more about how to size the electrical installation's input standard in this video.
