The S92 does not have a non-essential bus and, regardless, does not shed any buses after an engine shutdown. It uses MGB driven generators - not engine starter/generators.
That said, you do come across some odd wiring examples on different types, as Max Con says. The one that really struck me was reading the Air Transat A330 report, where they dumped all their fuel out of a leaking pipe over the Atlantic, at night, and then dead-sticked into the Azores. The CVFDR was shed after the second flame out, so the investigators lost the last 30 min of the flight! Turns out that that's a standard practice, but now being addressed.
