Voltage Drop Calculator
This calculator will estimate the voltage drop of an electrical circuit based on the wire size, distance, and anticipated load current. Please note this calculator assumes that the circuit is operating in a normal condition - room temperature with a normal frequency.
The actual voltage drop of your circuit may vary based on the condition of the wire, the conduit being used, the temperature, the connector, the frequency, etc. It is recommended that the voltage drop should be less than 5% under a fully loaded circuit condition.
