Panelboard and Switchboard Short Circuit Current Ratings

marked with their electrical ratings, including their SCCR. A typical marking would read, “Short-Circuit-Current Rating 65,000 RMS symmetrical amperes”. If the unit contains meter mounting equipment other than those for use with current transformers, they are also marked “Watthour meter not included in short-circuit-current rating”.

current supply, and LEDs are rated to operate within a certain current range (measured in amps). Therefore, too much or too little current can cause light output to vary or degrade faster due to higher temperatures within the LED. In summary, LED drivers convert higher voltage, alternating current to low voltage, direct current. They
