I'm running electric to a new shop building underground for about 185 feet. I'm considering using aluminum tri-plex #4 or #6 inside 1" PVC buried about 2 feet. I'll be running a 120V air compressor, an arc welder, and a 120V window A/C but not all at the same time. The reason I'm looking at the aluminum tri-plex is the cost which is .70/.85 cents a foot in my area. Is this the best and least expensive way to do this job ? I'm doing it myself so I'm not worried about code but I will have sufficient breakers on both ends. Any suggestions/ideas please ?
