Blair, for once I am not trying to be a smart a--, but how would you get the wire to go 350-400 yds.?
I'm not sure how Blair would do it, but many times in my career I've pulled cable that far, and further, through conduit and stuffing tubes of all kinds. For long runs like this, I generally start with a strong industrial vacuum cleaner attached at one end, and a roll of heavy string at the other end of the conduit. Let the vacuum cleaner suck the string through the conduit. Attach a much heavier line to the string, and pull it back through. Securely attach the cable to the heavy line -- then start to
heavily lubricate the cable and conduit. There are a number of different kinds of lubricants, for different conduit and cable jacket types, each with their own friction coefficients. A good electrical supply company can usually make recommendations.
