I posted on this a week or two ago and now have another question. Currently have aerial triplex to shop but need to run underground. Have a 100 amp panel in shop. Run from house will be about 180 feet. The previous question was related to awg and the consensus was that #2 was required. I agree. Before I go to the electrical supply house to buy cable and otherwise suffer sticker shock, I'd like thoughts on direct burial versus running schedule 40 and pulling the cable. It may be cheaper to use conduit rather than UF. Comments? Thoughts? BTW, when searching the internet and trying to locate prices, what should I call these things: UF? SE? What is the appropriate format to google? UF 2/3? Thanks
