I read prior questions and need to follow up before investing thousands in wire.
Starting at barn, need to run power to a sprinkler water pump (TSC model CLLS115) 900 ft away. Pump can run either 220V 10A or 115V 20A.
At water pump location I need pull chain light & 115V recep for sm heater or heat lamp in winter months.
Pump is used 1-2 x's per week for an hour. Barn has 2 unused 220V breakers. My plan to keep wire cost down is to use URD 4g Alum 3 strand wire (2 hots & a neutral) the 2 hots for the 2 sides of 220V & neutral for 115V need.
If I drove a ground rod at pump location for ground needs. The 2 hots for pump with ground & the neutral with a split off 1 of the 220V feeds & ground to a seperate 20A breaker for recep & light.
Upon cable reaching pump area I was told I need a disconnect I had planned on a 30A disco. I had planned to put a subpanel because of 115V need as your article stated.
In your prior question work you stated you needed a 220V breaker & 20A breaker at location. If I did the 220V breaker in panel at pump WOULD I NEED A DISCONNECT SWITCH AT LOCATION? however that would be 2 breakers on 1 -220V circuit or would the breaker at barn be enough?? Do I need disconnect also? If so does cable run into disco first then panel or vise versa? Which one is not necessary or both & where to go with cable first? - thought I would check before investing in disco & panel.
