F-2 System Loading and Heat Dissipation
Validate the System
The example systems shown in the tables below are verified to be acceptable
configurations. The systems are valid because:
• Calculated Current Values < Maximum Allowable Current Values
• Calculated System Loading < Maximum Allowable System Loading
