Applying Transfer Switch High WCR & Short-Time Rating To Simplify Electrical System Design
Transfer switches are critical components in the power system and they are tested to meet UL 1008 Standard for Safety - Transfer Switch Equipment. This course discusses some of the UL 1008 testing and passing criteria and then demonstrates that high short-circuit and short-time withstand and closing rating (WCR) help simplify the selection of overcurrent protection devices and enable selective-coordination strategies. This course also touches on switchboards (UL891) and switchgear (UL1558).
