Power cables of the distribution box are connected in series
There are two ways power supply channels can be connected: in series and in parallel. Channels must be floating and galvanically isolated to be connected. The total output voltage is the sum of the channels'. The power demanded in electricity systems also determines the cable cross-section and properties as well as the current to be transferred. In case of high power use, to meet the demand of currentAnd in order for the current to be carried at the demanded high powers to be met, the method of parallel. By connecting power supply channels in series or parallel, you can boost voltage or current to meet specific testing demands without additional equipment. Whether it's a simple household circuit or a complex industrial application, understanding the different wiring configurations is crucial for.
