How is TEK 90 referenced in the NEC? Does it meet the qualifications to be used inside an attic for instance? Finally the onestopbuy link was very light on info; are the cables inside stranded or solid?

Thanks,

William,

We get it with two pairs of color coded #8 copper and a #10 ground. Off the shelf you can get #14, #12, #10, #8, and #6 and on up to 500 MCM. The 14-10 go up to 10 conductors and the 8 and 6 go up to 4 conductors. Here's a URL, not the cheapest place, but to give you an idea: http://www.onestopbuy.com/wire-cable/Product-Price-Code-TK-40629.asp Graybar had the best price for us.

You can also get it custom in big quantities from some manufacturers.

If you support it every 18" or so it stays straight. The end connectors are a bit of a PITA to assemble. The key is to cut the end of the armor cleanly and as directed and then disassemble the connector and put it on piece by piece. Takes a couple of minutes.
