I am trying to do some work for dad and have figured out what i want to
do, but my lack of experience has me asking several questions.
Circuit #1 is for a maximum 2 hp water well to the house. I will be using outdoor rated romex. From the main breaker, we will run approx 150 ft. This distance is mostly inside the house. We then go outside and down one of the 2 x 8 rafters (along the center) on the carport. From there i plan on running the romex inside pvc pipe underground approx 4 ft so i can get to the well house disconnect. Total length inside the pvc pipe is 20 ft.
Since this is 125 - 150 ft, will i need to goto #8 due to wire length?
If so, can my main beraker will be 40 amp and the breaker at the pump will be 30 amps?
Can this be done with outdoor rated romex or do i need to jave a junction box
and splice the romex to thwn wire?
The next cable running along the same path is for an ac welder.
The input current is 42.5 amps. I was going to run a # 6 romex using the 75 degree column rated 65 amps, or should i go with #4 due to the length?
The size of the conduit i am planning to use is 1 1/2" based on fill.
all comments are much appreciated.
thanks in advance,
