About this app

This user-friendly software is designed to assist with power distribution system design, making it convenient for electrical technicians and engineers to use on the go.

※ Based on the latest Taiwan regulations, "User Electrical Equipment Installation Rules," released on May 9, 2025.

The auxiliary tools include:

* Load current calculation
* Conductor amperage (Tables 25-2, 25-3, 25-4, and 25-5)
* Voltage drop calculation (The voltage drop of the low-voltage main line and its branches shall not exceed 3% of the nominal voltage, and the total shall not exceed 5%)
* Conductor conduit selection (For conductors of the same diameter running in the same conduit, refer to Tables 328-1, 328-2, and 343-1)
* Conductor cross-sectional area calculation (For conductors of different diameters running in the same conduit, refer to Tables 328-6, 328-7, and 343-4)
* Grounding wire diameter lookup (For grounding wires for separate grounding of electrical equipment or connecting wires for grounding of electrical equipment and the internal wiring system, refer to Table 93-2)
* Recommended copper busbar specifications
* Power factor improvement calculation (Capacitor capacity should be designed to improve the power factor to 95%)

* Duty cycle and rated current percentage of discontinuously operating motors (Table 214)

* Low-voltage short-circuit fault current calculation (using 3 Type combinations, fault current estimation can be completed for various low-voltage systems below 600V)

* Indoor enclosure size reference specifications
