| Arc Flash PIQ Quiz is a Hot topic
The new Protection Intelligence Quiz (PIQ) on Arc Flash Hazard Protection, launched August 1st, is proving to be our most popular topic so far. If you haven't done so already, take the online quiz and test your knowledge of arc flash hazards and electrical safety. After you take the quiz you'll be directed to a "Learn More" page where you may download the PIQ Quick Notes, a one page summary of the Arc Flash Quiz, as well as other educational resources.

New White Paper Explains How to Reduce System Downtime by Correctly Coordinating Selectivity Between Overcurrent Protective Devices
 |
Selectivity between overcurrent protective devices is generally desirable and may be mandatory. Traditional time-current curve analysis may not accurately portray the degree of selectivity existing when current-limiting overcurrent protective devices are involved. It is important for designers to limit the outage to only that circuit which is overloaded or which has faulted in order to avoid shutting down healthy parts of the electrical distribution system. This white paper tech topic will discuss viable methods for evaluating selectivity between current-limiting fuses and non current-limiting circuit breakers.
This informative paper covers:
- Overview of NEC articles where Selective Coordination is required
- How fuses & circuit breakers operate
- How to read time-current curves & peak let-through graphs
- Two combinations & methods for evaluating selectivity
