I had PVC conduit laid before concrete was poured to where I wanted a Jacuzzi. I realized that it is 1 1/4” PVC conduit while measuring how long of a run I needed. The plan is to put a 50amp panel in the back yard for the hot tub. The run is approximately 95 feet from end to end of the conduit.(measured with pull tape) Voltage drop calculator says minimum 6awg. I had the idea of running 4awg to have more power in the backyard for future projects but would that be nearly impossible to pull with 1 1/4” conduit? Should I just do 6awg?
