How to calculate the current of a secondary distribution box
This total VA is then divided by the system voltage (typically 240V for a subpanel feed) to determine the minimum required current in Amperes. The secondary current is the current on the output side of a transformer, calculated based on the primary current and the ratio of primary to secondary voltages. Your Project's Total Power Demand This isn't just adding up wattages randomly. Do you really need the hair dryer, microwave, and vacuum running. Primary distribution systems consist of feeders that deliver power from distribution substations to distribution transformers. At this. Utilities may have some control over and access to the energy stored in electric vehicles attached to the grid. tribution system and the consumers meters. Generally, no tappings are taken from the feeder so that current in it remains the same throughout. This approach prevents running numerous long.
