Pond Fountain Voltage Drop Calculator

Estimate total circuit voltage drop and determine whether your fountain installation may benefit from a smaller motor, shorter cord length, heavier wiring or a higher-voltage.

Fountain & Electrical Specifications

The provided cord gauge will depend on the motor configuration and manufacturer. 12 AWG is the most common cord gauge provided, and is generally a reasonable baseline to use for calculations. To get the most accurate results, feel free to Contact Us to verify the provided cord gauge for your particular fountain.

Your Results

Select a motor, enter the main-panel distance, and choose the fountain cord length to see an estimate.

For single-phase installations only. These voltage-drop calculations are estimates using typical amperage ratings for pond fountain motors. These estimates do not establish conductor ampacity, breaker sizing, or suitability of a particular fountain model. All wiring must comply with applicable electrical codes and be evaluated and installed by a licensed electrician.
