Hi Bruce- Great Electrical Repair Question!
I would need to know the volts and the Amps or Watts of the pump as stated on the name plate or specifications to calculate this. Let me know -
Thanks for the response. The pump specifications are, 3/4 horsepower, 1-phase, 60 cycle, 3450 RPM, Voltage is 115/230, Amps=10/5, SF Amp 14/7. Cheers, Bruce.
Hi Bruce, Based on your information: If the pump is wired for 115 Volts the wire size should be #1 Copper. If the pump is wired for 230 Volts the wire size should be #6 Copper. These are minimum wire sizes based upon installation into a PVC Conduit with no more that 50% Fill Capacity. The wire size is for the current carrying conductors, Hots and or Neutral
The ground wire size may be de-rated or a ground rod may be installed at the pump location. You may also want to consider a Solar Powered Pump. Dave.
Hi Dave, I thought that it would require a good sized cable which is costly. I already have the pump but I am still looking into a wind turbine. I need to get some oxygen into the deep water of my pond. Last winter I lost all of my aquatic life due to a freak storm which brought 4 inches of rain in January which melted the ice, sunk to the bottom and forced the anaerobic layer to the upper levels. Thank you very much for your thoughts. All the best, Bruce.
