Iwire asked: "Why use a cable if a raceway runs from point to point"?
The aluminum SER I saw stuffed into a 2" pvc pipe underground was installed in a pvc pipe that was only continuous from where it exited one building into an LB and entered the other building through another LB...the SER cable was unbroken from panel to panel and the PVC was used just for the underground section of the feeder...eliminating the need for a juction to change wiring methods.
I'm not saying it's OK...just an installation that I question?
When I 1st looked in article 338, I looked for the "Uses not permitted" part that I see in most other articles...maybe it needs to be added for 2008...
