Carpenter working in a small strip mall went to remove what he thought was a plumbing waste or vent line. Turns out it was the three phase feed for the unit he was working in. Good thing the power was turned off. He didn't realize it until he was through all four lines. The electrician who wired the mall had schedule 80 on the exterior wall and SCH 40 DWV for the interior. Next door is a day care center.... The carpenter took the rest of the day off to reflect on his good fortune.
