I am just reviewing some the requirements of the nec. As per sec #300(k)I have never used any boring equipment, and have never seen any cables or raceways listed as such.

So what's your question? There is a thriving business doing this, and products are available.

Are these boring machines similar to those that bore pipe sideways under highways and such for gas lines, where it's all computer-directionally controlled? and the trays are sectional, lile 6" wide a piece, built like a hollow bike chain, and the cable running inside? or am I way off? I'd like to know. thanks! Brian
