Proper Electrical Wiring for Ponds and Water Gardens
Your pond will require electrical outlets to run the pump(s), filters, and lighting. It is prudent that plans are made for your electrical connections prior to pond installation.
Always install a ground fault circuit interrupter (GFCI or GFI) in each electrical outlet used by the pond. The GFI senses any electrical contact with water and will stop the flow of electricity immediately whenever contact is established. Pump wiring can sometimes become frayed and can come into contact with the pond water- the GFI outlet will prevent electrical accidents from happening.
Compare the power requirements of your pump, and all other electrical devices, with the amperage that your circuit can handle. Residential circuit breakers can usually handle 15 or 20 Amps per circuit, for 1,800 to 2,400 Watts.
Tip: The voltage of North American power outlets is 120 Volts.
Power (watts) = Amperage (current) * Voltage (volts)
Thus, to calculate the Amperage of your pump:
Amperage (current) = Power (total in Watts, of all electrical devices) / 120 volts
Calculate the total amperage draw (calculated with the formula above) of all of your electrical devices, and compare this with the amperage your circuit can handle.
Always call your local phone, gas, cable, and electricity providers to mark all underground utility lines on your property prior to digging. If you’re laying your own electrical lines, avoid any area with a septic system, paving, deck, or patio. The power line should be run through a PVC schedule-40 pipe that is buried at least 18 inches deep
