Short Circuit and Coordination Study with Arc Flash Hazard Analysis for a National Video and Ecommerce Retailer
We provided a short circuit study review and update of the entire electrical distribution system, including incoming utility service, primary switchgear, transformers, emergency generators, and all associated 480V and 208V distribution. Our team performed a review and update of the protective device coordination study of the electrical system and associated feeders to the nearest downstream overcurrent protective device past any adjustable settings. A review and update of the arc flash hazard analysis was also conducted and protective devices were checked for miscoordination from an arc flash perspective, and coordinated to trip the closest upstream circuit breaker to the fault.
