MRCOOL® TravelCool™ Electrical Requirements: Everything You Need to Know Before Installation
One of the most important parts of installing a rooftop RV air conditioner isn’t mounting it on the roof—it’s supplying it with the correct electrical power.
The MRCOOL® TravelCool™ RV Inverter Heat Pump uses advanced inverter technology that automatically adjusts compressor speed based on heating and cooling demand. Because the compressor operates differently than older fixed-speed rooftop air conditioners, following the manufacturer’s electrical requirements is essential for reliable performance and long equipment life.
Before installing your new TravelCool™ system, verify that your RV electrical system meets the recommended specifications outlined below.

MRCOOL® TravelCool™- Install Manual
Electrical Specifications
The MRCOOL® TravelCool™ operates on:
Voltage
120 Volts AC
Frequency
60 Hertz
Phase
Single Phase
This electrical configuration is common in North American RVs and campers.

Recommended Breaker Size
The installation manual recommends:
16-Amp Dedicated Circuit
A dedicated breaker helps ensure the TravelCool™ receives a stable power supply while reducing the chance of nuisance breaker trips caused by sharing the circuit with other high-demand appliances.
Why a Dedicated Circuit Matters
A dedicated electrical circuit is recommended because it:
- Provides consistent voltage
- Reduces electrical interference
- Helps protect inverter electronics
- Minimizes nuisance breaker trips
- Supports reliable heating and cooling performance
Sharing the circuit with other large electrical loads may reduce system performance.
Power Consumption
The TravelCool™ inverter compressor automatically changes speed based on demand.
Cooling Power Consumption
1,000–1,650 Watts
Heating Power Consumption
1,000–1,400 Watts
Rather than operating at full output continuously, the inverter system adjusts compressor speed to match the indoor temperature. This helps improve comfort while reducing energy consumption.
Cooling Capacity
10,000–15,000 BTU per hour

Heating Capacity
12,000–16,000 BTU per hour
The variable-speed compressor continuously adjusts output to maintain a more consistent interior temperature compared to many traditional rooftop air conditioners.
Grounding Is Essential
Always ensure the TravelCool™ is properly grounded according to the installation instructions and applicable electrical codes.
Proper grounding helps protect both the equipment and occupants from electrical faults.
Before Connecting Power
Before energizing the system:
✔ Verify all wiring connections.
✔ Confirm breaker size.
✔ Check voltage.
✔ Ensure the roof installation is complete.
✔ Inspect all electrical connections.
✔ Confirm the air distribution box is installed correctly.
Common Electrical Mistakes
Avoid these installation errors:
❌ Using an undersized breaker
❌ Sharing the circuit with other heavy electrical loads
❌ Loose electrical connections
❌ Failing to verify voltage
❌ Operating without proper grounding
❌ Skipping the final electrical inspection
Frequently Asked Questions
What breaker size does the MRCOOL TravelCool use?
The installation manual recommends a 16-amp dedicated circuit.
Does the TravelCool run on 120 volts?
Yes.
It operates on 120V AC, 60 Hz, single phase power.
Does it need its own circuit?
Yes.
