## # How to Calculate 3 Phase Panel Load

### Introduction

A three-phase panel is a type of electrical distribution panel that is used to distribute power to three-phase loads. Three-phase loads are common in industrial and commercial applications, and they can be used to power a variety of equipment, such as motors, pumps, and air conditioners. When sizing a three-phase panel, it is important to correctly calculate the total load that the panel will need to support. This can be done by adding up the power ratings of all of the individual loads that will be connected to the panel. The total load of a three-phase panel is typically expressed in kilowatts (kW). To calculate the total load in kW, you can use the following formula: ``` Total load (kW) = Sum of individual load ratings (kW) ``` For example, if you have a three-phase panel that will be used to power a motor with a power rating of 5 kW, a pump with a power rating of 3 kW, and an air conditioner with a power rating of 2 kW, the total load of the panel would be 10 kW.### Calculating the Load per Phase

Once you have calculated the total load of the three-phase panel, you need to divide the total load by the number of phases to determine the load per phase. The load per phase is typically expressed in amperes (A). To calculate the load per phase, you can use the following formula: ``` Load per phase (A) = Total load (kW) / Number of phases ``` For example, if the total load of the three-phase panel is 10 kW and the panel has three phases, the load per phase would be 10 / 3 = 3.33 A.### Sizing the Three-Phase Panel

When sizing a three-phase panel, it is important to make sure that the panel is large enough to support the total load. The panel should also have enough space for the number of circuit breakers that you need. The size of the panel is typically expressed in amps (A). To determine the size of the panel, you can use the following formula: ``` Panel size (A) = Load per phase (A) * Number of phases ``` For example, if the load per phase is 3.33 A and the panel has three phases, the panel size would be 3.33 * 3 = 10 A.### Installing the Three-Phase Panel

Once you have sized the three-phase panel, you can install it in your electrical system. The panel should be installed in a location that is accessible for maintenance and repairs. The panel should also be installed in a location that is protected from the elements. When installing the panel, it is important to follow the manufacturer's instructions. You should also make sure that the panel is properly grounded.### Conclusion

Calculating the load of a three-phase panel is a relatively simple process. By following the steps outlined in this article, you can easily determine the size of the panel that you need for your application. ### Additional Resources * [How to Size a Three-Phase Panel](https://www.electricaleasy.com/how-to-size-a-three-phase-panel/) * [Three-Phase Panel Load Calculation](https://www.engineersedge.com/electrical/three-phase-panel-load-calculation.htm) * [Installing a Three-Phase Panel](https://www.homedepot.com/c/how-to-install-a-three-phase-panel-H-550)Single Phase Panel Schedule Shows As Three Autodesk Community Revit Products
