I don't know about the incidents that you quote but as this goes along farther it gets even more unbelievable.
The 30 Amp receptacle has 3 conductors, right ??
And a 220 receptacle has 4 conductors, right (hot, hot, neutral and ground) ??
If the "electrician" runs two hots (4 wires) to a 3 conductor receptacle.....where does he connect the 4th wire ??? Or which of the remaining two conductors does he connect to the one remaining lug ??
I can see a rank amateur screwing this up but not a real electrician.
As I said earlier, the connection at the receptacle MAY be identical, it's how the wires are connected at the panel that makes the difference.
30A RV (110V) = 1 breaker, one hot, one neutral (plus ground)
30A Welder etc (220V) = double breaker, two hots, one ground. NO Neutral.
No reason for ANY electrician to run a 4-wire cable to a 30A 3-pin receptacle under ANY circumstances so your question about what to do with the 4th wire becomes irrelevant.
