Welcome to our full load current calculator!

To calculate the full load current of a device or circuit, you will need to know the following information:

- The voltage of the circuit (V)
- The power rating of the device or circuit (W)
- The power factor of the device or circuit (PF)
- Whether the circuit is single-phase, 3-phase or DC

Let's begin!

The full load current is the amount of current that a device or electrical circuit is rated to carry continuously, without overheating or damaging the conductors. Knowing the full load current of a device or circuit is important to properly size the conductors, overcurrent protection devices, and power supply.
