Disaster Recovery Drill
Sunday, March 1st, 2009
With the push of this button, the air circuit breaker is switched off, and the disaster recovery (DR) drill is officially started. Yes, if you notice from the photo, the circuit breaker is huge. It is not like any common circuit breaker you find in your household electrical panel. This is a huge circuit breaker sized for 2500 amperes 3-phase current. It’s 415V, more than the typical 230V household power supply, but in the grander scheme of things, this is still considered “low tension”.
