Arc Flash Labels

ESAD’s arc flash labels are prepared by a professional engineer and based on an in depth arc flash analysis as documented in NFPA 70E 2012 and IEEE 1584 and IEEE 1584a. Our labels include the PPE Level, Arc Flash Boundary, Incident Energy, Shock Hazard Exposure, Nominal System Voltage, and the Approach Boundaries.

Fault Current Labels

ESAD’s fault current labels are prepared by a professional engineer and based on an in depth fault current analysis. Labels based on maximum available fault current from utility transformer are not allowed. Our labels are based on calculated fault current and conform to the 2011 National Electrical Code Article 110-24.

Relay Coordination

One of the most critical aspects in a power system is power protection. Power protection involves using protective devices to insure that in the case of a short circuit or electrical fault, system components are not damaged and as little of the system is taken down. In order to provide adequate protection for the circuit, these fault conditions must be simulated and analysis. ESAD will analyze your system and determine the best protective device coordination to achieve optimum equipment protection and selectivity.
