I am installing a subpanel 220v residential service. I used the spreadsheet provided on this website. However, it seems to use a different formula than I have seen before....(2*K*L*I)/D.... The spreadsheet says that L is already 2* the conduit length.... Why is 2* included in the formula. Also, I have used a K of 10.09 for copper before. What is the right formula?
What size wire do I need for a 165 feet conduit? What is the maximum voltage loss allowed by the Code? I would like to have 60 amps of continuous power. Thanks
