The wires that were installed into the conduit pipes to the junction boxes were up to nine individual wires that had to be pulled through the pipe. The proceedure required a stiff fish wire to be pushed through the pipe out the other end. Then the wires were fastened to the fish wire with tape and as the wires were pulled through the pipe they were continually gooped up with some kind to slick stuff to make them slide through the pipe easier. It was quite a process to watch for sure. I learned quite a lot about electrical wiring.
