1. Introduction and Product Overview
The Surge Guard 40350-RVC is a hardwire automatic transfer switch designed to provide premium electrical protection and seamless power management for recreational vehicles (RVs). This unit continuously monitors incoming shore power and automatically switches to generator power when shore power conditions are outside acceptable limits. It integrates RVC communication for displaying voltage, current, and fault conditions on compatible devices, ensuring comprehensive electrical system oversight.
Key features include a 65A, FLA full-rated contactor mounted on vibration isolators for quiet operation, UL1008 approval for full transfer switch rating, and 3350 Joules of power surge protection. This device is engineered to safeguard your RV's electrical system from faulty park power and generator power fluctuations.

2. Safety Information
Read and understand all safety instructions before installing or operating this device. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Professional Installation Recommended: Installation of this 50 Amp hardwire transfer switch involves high voltage electricity. It is strongly recommended that installation be performed by a qualified electrician or RV service technician.
- Disconnect Power: Always disconnect all power sources (shore power and generator) before performing any installation, maintenance, or troubleshooting on the unit.
- Proper Wiring: Ensure all wiring conforms to national and local electrical codes. Use appropriate gauge wiring for 50 Amp service.
- Ventilation: Install the unit in a well-ventilated area, away from flammable materials.
- Moisture Protection: Ensure the installation location protects the unit from direct exposure to water or excessive moisture. The unit has an IP54 rating, indicating protection against dust and splashing water, but it is not submersible.
- No User Serviceable Parts: Do not attempt to open or repair the unit. Refer all servicing to qualified personnel.
3. Installation Guide
This section provides general guidelines for installing the Surge Guard 40350-RVC. For detailed wiring diagrams and specific instructions, refer to the complete installation manual provided with the product packaging.
3.1. Choosing an Installation Location
Select a dry, protected, and well-ventilated area within your RV, typically near the main electrical panel or where shore power enters the vehicle. Ensure there is sufficient space for wiring connections and future access for inspection.
3.2. Wiring Connections
The 40350-RVC is a hardwire unit and requires direct electrical connections for shore power input, generator input, and RV load output. All connections must be secure and properly insulated.
- Shore Power Input: Connect the 50 Amp shore power line directly to the designated input terminals on the transfer switch.
- Generator Input: Connect the generator's 50 Amp output line to the designated input terminals on the transfer switch.
- RV Load Output: Connect the main electrical panel of your RV to the designated output terminals on the transfer switch.
- Grounding: Ensure proper grounding of the unit according to electrical codes.
- RVC Communication: Connect the RVC communication cable to the appropriate port on the transfer switch and to your RVC compatible device for monitoring.
After all connections are made, double-check all wiring for tightness and correct polarity before restoring power.
4. Operating Instructions
The Surge Guard 40350-RVC operates automatically to manage your RV's power source.
4.1. Automatic Power Transfer
When both shore power and generator power are available, the unit prioritizes shore power. If shore power is connected and stable, the unit will draw power from it. If shore power is disconnected or its voltage/frequency falls outside safe operating parameters, the unit will automatically switch to generator power, provided the generator is running and producing stable power.
4.2. RVC Monitoring
The RVC communication feature allows for real-time monitoring of your electrical system. Through an RVC compatible device (sold separately), you can view:
- Incoming voltage from shore power or generator.
- Current draw.
- Active power source (shore or generator).
- Fault conditions or error codes.
Consult your RVC compatible device's manual for specific instructions on accessing and interpreting this data.
5. Maintenance
The Surge Guard 40350-RVC is designed for minimal maintenance. However, periodic inspection is recommended to ensure optimal performance and safety.
- Visual Inspection: Annually, or more frequently if operating in harsh conditions, visually inspect the unit for any signs of physical damage, corrosion, or loose connections.
- Cleanliness: Keep the area around the transfer switch clean and free of dust, debris, and obstructions to airflow. Do not use harsh chemicals or abrasive cleaners.
- Wiring Integrity: Check all electrical connections for tightness. Loose connections can lead to overheating and potential hazards.
- Ventilation: Ensure that the ventilation openings are not blocked.
If any issues are observed, or if the unit is not functioning as expected, refer to the Troubleshooting section or contact qualified service personnel.
6. Troubleshooting
This section provides solutions for common issues. For complex problems, contact customer support.
| Symptom | Possible Cause | Solution |
|---|---|---|
| No power to RV from shore or generator. | Shore power not connected or faulty; Generator not running or faulty; Main breaker tripped; Loose wiring connection. | Verify shore power connection and source; Check generator operation; Reset main breakers in RV and at power pedestal; Inspect wiring for tightness. |
| Unit not transferring power automatically. | Input power (shore or generator) outside acceptable voltage/frequency range; Internal fault. | Check voltage and frequency of both power sources; If power sources are stable, contact customer support. |
| RVC communication error. | Loose RVC cable connection; Faulty RVC cable; Incompatible RVC device. | Ensure RVC cable is securely connected at both ends; Try a different RVC cable if available; Consult RVC device manual for compatibility. |
| Unit making unusual noises. | Contactor wear; Loose components. | While the contactor is designed for quiet operation, persistent or loud unusual noises may indicate an issue. Disconnect power and contact qualified service personnel. |
If troubleshooting steps do not resolve the issue, contact Surge Guard customer support or a qualified RV technician.
