Running Two Camper Trailers Off the Same Circuit Breaker System: A Comprehensive Guide
When planning a camping trip with two camper trailers, one of the common questions that comes up is whether it is possible to run both units off the same circuit breaker system. This article provides a detailed guide on the feasibility of this setup, along with the necessary precautions and considerations.
Maximizing Power Supply
The main question that needs to be answered is whether the circuit breaker system has the necessary ampere and wattage supply to support the maximum load requirements of both camper trailers. In most cases, if the system is sufficient in terms of ampere and wattage, it is indeed possible to run two camper trailers off the same circuit breaker system. However, certain precautions and limitations apply to ensure a safe and efficient power distribution.
Key Considerations
1. Avoid Running Heavy Loads Simultaneously: While the standard 30-amp breaker can support a considerable amount of power, approximately 3600 watts, it is advisable to avoid running heavy loads like air conditioners, heavy appliances, or large power tools simultaneously. For instance, running the air conditioner on both trailers would be problematic, as it can exceed the breaker's capacity and cause it to trip.
2. Optimal Load Distribution: A single 30-amp breaker can safely handle around 20 amps when two camper trailers are using it. This means that lights, fans, and small appliances like televisions and refrigerators can be used without issue. However, using power-hungry devices such as a microwave or an electric fireplace can easily blow the breaker. Therefore, it is crucial to carefully manage the load distribution to avoid overloading the system.
3. Use Gas-Operated Devices: To avoid overloading the electrical system, it is recommended to use gas-operated devices for tasks such as refrigeration and water heating, instead of electric units. This ensures that the primary power supply is reserved for essential electrical appliances.
Practical Options for Power Distribution
For those with multiple camper trailers, there are practical options to consider if you want to run both units off the same breaker system without causing overcrowding or safety hazards.
1. Using a Splitter Cable
If your available outlet is a 50-amp dual-phase outlet, you can use a splitter cable to create two 30-amp services. This is the easiest and most electrically safe method. However, if you only have a 30-amp outlet, a splitter cable can still be used to provide two 15-amp services, but running the air conditioners in both trailers would be impossible. In either case, it is important to understand the maximum load each RV requires and ensure that the breaker is wired to cover at least that amount. Careful and controlled use of power is also crucial to avoid overloading the system.
2. Splitting the Load Properly
If you and your fellow camper plan to run two RVs at full outlet current, you need to be cautious. Running both units simultaneously means pulling a significant amount of amps, which can easily exceed the breaker's capacity and cause it to trip or even start a fire. Therefore, it is advisable to inform all users in both RVs to limit their electric usage and to use power-saving devices where possible.
Conclusion
While it is technically possible to run two camper trailers off the same circuit breaker system, it is crucial to understand the load requirements and limitations of your electrical setup. By managing the load distribution carefully and using appropriate devices, you can ensure that your camping trip is enjoyable and safe. If in doubt, consult a professional electrician to ensure that your setup meets all safety and legal requirements.
