DC Solar Array - Arc fault demonstration
Why people recommend it
Cited as a demonstration of how readily high-voltage DC sustains an arc, supporting advice to use switches properly rated for DC.
Watch for: dramatic high-voltage footage, a hazard demonstration and not a method
In their words
High DC voltage is the worst to break, and indeed most of these will instantly catch fire because a decent solar array will be able to pull an arc of an inch or more.
