Where is 3-phase supply commonly found?

A 3-phase supply is commonly found in commercial, agricultural, and some apartment properties due to its efficiency and ability to handle larger loads compared to single-phase power. This type of electrical supply is ideal for businesses that require high power for equipment such as HVAC systems, elevators, and industrial machinery.

In agricultural settings, 3-phase power is often used for large motors in machinery and irrigation systems, which benefit from the smoother power delivery and less fluctuation in power quality. Some larger apartment complexes may also utilize 3-phase supply to ensure sufficient energy distribution for common areas and shared facilities.

While residential properties often utilize single-phase power due to lower energy demands, and industrial settings do indeed have robust 3-phase systems, this does not exclude other types of properties from benefiting from 3-phase service. Additionally, rural environments may have limited access to such supplies, further illustrating why other settings are more common for 3-phase electrical systems.
