sounds like a excellent way to start a fire
IDK that it's much different than doing the same thing with a 20A
circuit. You'd get a bit more arc for milliseconds, but it doesn't
seem that much worse at 30A.
Forgot that it's also 220V, instead of 120V, so I guess the available
energy for arcing is 3X what it is here with a 120V, 20A circuit,
so I agree, you have a point. How much more likely that is to start
a fire in the milliseconds before the breaker trips, IDK. It would
depend on what's around to ignite.
