I have noticed that in my plant (large food manufacturing plant), the electrical conduit to various machines varies. In some cases it ls simple conduit that you see all the time in home electrical and in other cases it is heavy metal piping (similar to water pipes) but is running electrical. I'm wondering if the heavy pipe is just for strength in an area that sees forklift traffic and could stand up to being bumped into or is the some code that controls this.

I'm asking because we just closed down a plant and I have an opportunity to pick up pipe that I could use in my backyard to add some outlets along the back fence for yard lighting. It seems like overkill but it's very high quality, galvanized, 1/2" x 10' pipe.

Any thoughts from the experts here?
