Recently I was troubleshooting/repairing parking lot plugs in a fenced compound used exclusively by a school bus company. All of the wiring, starting right at the panel, was Aluminum. This was not an older installation and based on the overall appearance of the parking lot I'd say it was a "money saving" installation in every which way possible. It's not often I find Aluminum wiring unless it's in a house that was built in the 70's. The only time I've heard of Aluminum being the preferred choice in recent years was when I was still in school. One of my instructors said that Aluminum was a reasonable choice for residential service conductors because it's cheaper. I remember a few classmates taking issue with that comment. Anybody here use Al for certain jobs?
