PWG297766 - Arch Flash Study and Labelling

It is the intent of this project for the consultant’s to provide a current Arc Flash Study for the three buildings identified, RH Coats, Jean Talon and Main Stats which will include the required study, label identification and subsequent label affixing.  Existing Arc Flash Studies will be made available to the successful bidder and can be used as a reference for this procurement.
The completed Arc Flash Studies will include but limited to the following headings
 
 

• Calculation of the maximum short circuit currents throughout the 600 - 208 Volt Distribution System
• Determination of protective device settings and sizes
• Calculations of the estimated arc current
• Determination of the arcing time based on the protective device characteristics and the contributing arcing current
• Calculation of the incident energy for the equipment at the given working distance
• Determination of the hazard/risk category (HRC) based upon the estimated incident energy level
• Determine the flash protection boundary for the equipment
