I am am planning to put in a sub panel via an old 3/4 flex conduit that housed an old dryer feed to make completion of a basement bath and two other rooms easier. The house has aluminum wiring which I plan to replace as I go, but I don't want to tie in to it for my new areas.
I've got four question/concerns: 1) the run length and drop in amps, 2) the max size conductors that I can should run to make the pull manageable, 3) using a twist-in couple on the flex, and 4) what size ground should be pulled back to the main.
My main panel is 100 amp located in the garage and I'd like to run the sub using #6 or #8 copper.... (3+G) I want to extend the flex conduit (total length 90') with a twist-in coupler.
Any information would be greatly appreciated. Thanks!
