Indicators On DC Breaker You Should Know

Unless they *explicitly* state the voltage ranking is DC, I'd personally assume it is actually an AC voltage rating and that they're currently being deceptive on objective.

I thought was vtMaps did--The arcing situation was only a difficulty for when the breakers vacation...
