What size of Parallel conductors would I need for 800 amp service if it was installed in single conduit? Size of conduit? (single phase and 3 phase)
Welcome to the Forum...
Often it is more productive if you provide us with your input rather than us simply "doing the math". What size would you think.
Sorry, I'm new on forum and didn't know about "exam" questions. I didn't think they would work. 600 MCM was the largest multiple choice question and after I derated, I found it not to work and just answered with the largest. It bothered me, and that is why I had to find out the answer. My problem might be that I misunderstood about the conduit. Derating might not be necessary if in 2 conduits, but I thought by the way it was worded, that it meant a single conduit.
