Short Circuit Current Rating (SCCR)
THIS PANELBOARD HAS A MAXIMUM SHORT CIRCUIT CURRENT RATING OF 100,000 AMPS RMS SYMMETRICAL, 120/240V~. THE ACTUAL RATING IS DEPENDENT ON THE BRANCH BREAKERS INSTALLED IN THIS PANELBOARD AND THE MAIN/FEEDER BREAKER, IF ANY, INSTALLED AHEAD OF THIS PANELBOARD. THE CORRECT MAIN BREAKER/FEEDER/MAIN BREAKER/BRANCH BREAKER SERIES COMBINATIONS TO BE USED ARE LISTED IN THE TABULATION BELOW. ANY CIRCUIT BREAKER INSTALLED, REPLACED, OR ADDED IN THIS PANELBOARD MUST BE MANUFACTURED BY SIEMENS AND MUST BE OF THE CORRECT TYPE AS INDICATED IN THE TABULATION BELOW. USE OF OTHER CIRCUIT BREAKERS IN THIS EQUIPMENT MAY VOID THE WARRANTY.

Diagram Description
The diagram illustrates the internal connections for the load center, showing the main line, neutral, and equipment ground bus bars.
- LINE: Two connection points labeled A and B are shown for the incoming line.
- NEUTRAL: Two neutral bus bars are present, labeled N1 and N2. The text indicates that the installed neutrals limit the panelboard to 30 circuits requiring neutral connections, with ECNBX kits available for up to 40 circuits.
- EQPT GND: Equipment Ground connections are depicted.
Key indicators in the diagram:
- NEUTRAL BUS FOR PLUG-ON NEUTRAL CIRCUIT BREAKERS
- BOND WHEN REQ'D
- BACK-FED BRKR WHEN USED
