What wiring configuration is used when wiring a transformer for low voltage, such as 240V?

The correct choice involves using parallel wiring when configuring a transformer for low voltage applications like 240V. In parallel wiring configurations, multiple secondary winding connections can be made, allowing for the output voltage to remain at a specified low level while providing increased capacity or current handling.

The use of parallel wiring ensures that the voltage remains consistent across multiple branches, making it ideal for applications that require uniform low voltage supply. This approach is particularly useful in situations where multiple loads need to be powered at the same voltage, such as in residential or commercial lighting and heating systems.

In contrast, series wiring is typically used for different voltage requirements, which could result in higher total voltages that are not suitable for low voltage applications. Monophase wiring generally refers to a single-phase electricity supply rather than a specific transformer connection method, while multiple voltage wiring usually implies a complex setup involving transformers that adjust to various voltages but may not specifically address the need for low voltage in a straightforward manner.
