3.8. Load Connections
Cable Size Considerations
The DC load cable(s) should be sized sufficiently large to limit the voltage drop from the MX28B DC power plant to the loads per system design requirements. The cable(s) must also carry the full load current during battery operation. During battery operation the voltage will be lower and for constant power loads, therefore the current will typically be higher. If assistance is required to determine the necessary cables for the application, contact your sales representative or APC.
Circuit Breaker Connections (1 to 50 Amps)
Connections for 1 to 50 amp DC loads require standard
