There are many reasons why you may want to convert your 3-phase electrical system to a single-phase 220V system. Perhaps you’re moving into a new home or office space with only a single-phase electrical system or upgrading your equipment to run on single-phase power. Whatever the reason, converting from a 3-phase to a single phase is not as difficult as you may think.
Understanding 3-Phase and Single-Phase Power
Before we dive into converting your electrical system, it’s important to understand the difference between 3-phase and single-phase power.
3-phase power is a type of electrical power commonly used in industrial and commercial settings. It uses three separate wires to transmit power, each with a different phase angle. This allows for more efficient power transmission and can support larger loads.
On the other hand, single-phase power uses only one wire to transmit power. It is more commonly found in residential and small commercial settings.

How to Convert 3 Phase to Single Phase 220v
You can convert a 3-phase electrical system to a single-phase 220V system by following these steps:
Determine the voltage of your 3-phase system: The voltage of your 3-phase system can typically be found on the electrical panel or by consulting a licensed electrician.
Calculate the voltage of your single-phase system: Using the formula: A single phase voltage is equal to 3 phase voltage / 3, where √3 is the square root of 3 (approximately 1.73)
Get the help of a licensed electrician: This step is important to ensure the safety and proper installation of the new single-phase system and comply with local building codes and electrical regulations.
Install a transformer: Step down the voltage from your 3-phase system to the appropriate level for your single-phase system by installing a transformer.
Connect the new single-phase system: Have a licensed electrician install and connect the new single-phase system according to local building codes and electrical regulations, ensuring proper grounding.
Test the new system: Once you connect the new single-phase system, have the electrician test it to ensure proper function and correct voltage.
3 Phase to Single Phase 220v Conversion Formula
The formula to convert 3-phase voltage to single-phase voltage is:
Single Phase Voltage = (3-Phase Voltage) / √3
Where:
- 3-Phase Voltage is the voltage of the 3-phase electrical system
- After a single-phase system is converted, it has a voltage known as the Single Phase Voltage.
- √3 is the square root of 3 (approximately 1.73)
It’s important to note that you can use this formula to calculate the voltage of the single-phase system after the conversion. It is not used to perform the conversion itself. A licensed electrician should do the actual conversion process, which may involve a transformer to step down the voltage.
Safety Precautions
It is important to note that converting your electrical system can be dangerous. And should only be attempted by a licensed electrician. Working with electricity can be dangerous and cause serious injury or death if not done properly.
Additionally, it’s important to ensure that you connect the new single-phase system to the ground. And that local building codes and electrical regulations do all wiring.
Final Thoughts
Following these steps and working with a licensed electrician, you can successfully convert your 3-phase to a single-phase 220V system. With the right knowledge and tools, you can ensure that your new system is safe, efficient, and able to support all your power needs.
