Therefore, no need for a control box? And Ray's suggestiong for a subpanel would work? Ray, Is the 14ga whip tha wiring for the v circuit coming out of the subpanel? If I use a subpanel, then is there any ground wire connected back to the main panel 60 ft away in a separate building? Bruto, The existing plug is a 2-wire with ground red, black, green. Thanks to all for inputs. I propose to do the following Install 2 pole 20amp breaker at main panel.
At the subpanel do not connect the ground to same bus as neutral. Use separate bus. This from Bruto's Sticky Note line diagrams which are very helpful. At Pumphouse 3. Outlet would be used to power pressure switch for pressure tank located in the pumphouse.

On the ft run of 12 your voltage drop would be 9. OK for lights but no motors. Go over 8 amps to say 15a and way to much voltage drop. Suggest a minimum of 10 on the ft run. Even then at 15a you would be looking at an Ok for lights but marginal for motors. Thanks Ray, For next year or two the only load at the future barn location would be lights and a water tank deicer.
Currently we only have a shelter. Later we'll build a barn and connect the electrical to a house panel which will shorten distance to ft and allow more load. We will pull 10s from subpanel at the pumphouse to the shelter location. Back to this question Is 30 amp breaker and 10's enough? Yes 10 on a 30a 2-pole breaker should be fine to the pump house. Give you a bit extra to play with.
Remember electric is like money once you have it you find uses for more of it. The temporary 12 to the barn at feet would be OK for lights but I wouldn't try to run something like a circular saw on it. Got it! No motors!. That will be the generator's job as needed for the next couple years. Thanks all. Related Articles. Well Pump Wiring. I currently h I have a v water well pump, submersible this is for farm use.
