Sounds like this ancient XKCD: https://xkcd.com/242/ (Normal person doesn't pull the lever again; scientist wonders if that happens every time. I assume the engineer does, too...)
The scientist’s job is to get zapped until they figure out why. The engineer’s job is to get zapped a couple times while they wire that thing up into the power grid.
