Hey All,
I bought a house that has a shed with a 120/240 subpanel. One of the 120 leg wires is out. When we tried to pull the old wire out of the conduit it isn't budging. It looks like the previous owner put in a few nasty 90 degree bends and the wire nearly filled the conduit anyway.
There is a huge concrete driveway between the main box and shed and there isn't a good path to get to dirt and bury a conduit.
I am running running 3 #8 (120, 120, N) and 1 #10 (GR) THWN from a 40A breaker on the main box. Ground rod at shed is taken care of.
I am going to have to resort to above ground conduit.
What size of conduit should I use? The old conduit was 3/4" and I have been told 5 #8 THWN can fit, but now that I can't use the old conduit, is 3/4" the right size or would 1" be better to go with to make it easy to pull the wires through? What should the conduit be made out of? Is there anything you would put around the conduit to make it any stronger? If I am running it over sidewalk what is the appropriate way to do it? Any other pointers to give me so that I don't have to replace conduit for quite some time?
Thanks in advance for the advice!
