What is the standard EMF required for the units in an 8 unit townhouse project?

In residential construction, especially in the context of a townhouse project, the commonly accepted standard for electrical systems is 230VAC. This voltage level aligns with European standards and some aspects of international practices, where 230VAC is typically used for household power supply.

The significance of 230VAC lies in its ability to effectively power the variety of electrical appliances and systems typically found in a townhouse, including lighting, heating, and kitchen appliances. Additionally, it allows for consistent performance with electrical devices, ensuring safety and reliability across the housing units.

This standard is essential for compliance with local codes, which often specify particular voltage requirements for residential buildings. In contrast, the other voltage options provided do not represent the standardized voltages widely accepted in residential applications. 240VAC might refer to a nominal voltage used in some regions, while 220VAC and 215VAC do not reflect the commonly referenced values in current electrical standards. Thus, 230VAC is the most accurate and accepted answer for the standard EMF required in an 8 unit townhouse project.
