21K? The 1000MCM was scrapping for $$ a long time ago. We'd cut us off a slice on the back end of a old scrap spool and go get emergency lunch money. 2 feet would buy us a $6 happy meal. Can you use AL 1000MCM? may be 1/3 price of copper.
According to the engineer, to use the aluminum wire, I'd have to go with 1500 mcm which costs nearly the same as the 1000 million copper, .29 cents a foot difference
