Components:
* Battery: Provides power for appliances and accessories when the trailer is not connected to shore power.
* Converter/Charger: Converts 12V DC from the battery to 120V AC for use with appliances. It also charges the battery when the trailer is connected to shore power.
* Shore Power Inlet: The point where you connect the trailer to an external power source (usually 30 or 50 amp).
* Circuit Breaker Panel: Protects individual circuits from overload.
* Wire Harness: Connects all the components and appliances within the trailer.
* Appliances: These include refrigerators, lights, water heater, air conditioner, microwave, etc.
* 12V DC System: Powers accessories like lights, fans, water pumps, etc.
* 120V AC System: Powers appliances and outlets.
* Grounding System: Ensures safety by providing a path for electrical current to safely return to the ground.
Diagram Flow:
1. Shore Power: When the trailer is connected to shore power, electricity enters the shore power inlet and passes through the circuit breaker panel, distributing power to the various circuits within the trailer.
2. Converter/Charger: The converter/charger uses the shore power to charge the battery and also converts DC to AC for appliances.
3. Battery: When the trailer is not connected to shore power, the battery provides 12V DC to the 12V system.
4. 12V DC System: The 12V DC system uses the battery to power lights, fans, water pumps, and other accessories.
5. 120V AC System: The converter/charger provides 120V AC power to the appliances and outlets within the trailer.
6. Grounding System: The trailer's electrical system is grounded to ensure that electrical current has a safe path back to the ground in the event of a short circuit or other electrical fault.
Important Considerations:
* Amperage: Be sure to connect your trailer to a power source with an appropriate amperage rating to avoid overloading the system.
* Circuit Breaker Protection: It's crucial to have appropriate circuit breaker protection for all electrical circuits within the trailer.
* Grounding: Proper grounding is essential for safety.
