Transfer switch Torque Verification
1. Disconnect shore power. Turn battery disconnects to the off position.
3. Once access has been gained to transfer switch, remove cover using a 1/4” socket to loosen set screw.
4. Once cover has been removed from the transfer switch using an in.lbs torque screwdriver /wrench tighten each conductor lug to the specified torque indicated on the inside of the transfer switch cover or in the installation instructions.
5. Torque specs listed on the inside of the transfer switch cover.
Tools Needed
1. Screw gun with number two square bit.
2. 1/4” socket or wrench.
3. IN.LBS torque screwdriver or wrench.
4. 5/32” hex bit.

- Nirakoka RV Automatic Transfer Switch has been pre-wired to automatically change the primary source of AC current from shore power to generator or inverter power when activated.
- WIDE APPLICATION — Applied to RVs, speedboats, and various high-power equipment that requires emergency power supply.
- AUTOMATICALLY SWITCH — This Automatic Transfer Switch 50 AMP can be used to automatically switch between inverter power and a generator. It switches to inverter power when the generator stops running. In the event of a inverter power outage, the generator will start automatically. The green L.E.D is lit when generator power is present.
- DOUBLE PROTECTION — Double protection of built-in mechanical interlocks and control circuits prevents two separate 120/240 volt AC power sources from entering the AC distribution board at the same time and causing a short circuit.
- TIME DELAY CIRCUIT — Once AC power from the Generator is sensed by this RV Automatic Transfer Switch, it will start a timer and automatically switch over to generator power supply after a 20-45 sec delay which ensures the generator has sufficient time to run up to speed before electrical load is applied.
- Seamlessly integrates with inverters, shore power, and generators for reliable electricity management.
- Provides automatic power switching between two separate 30 amps AC input sources.
- Features a time delay of 20-30 seconds to allows the generator voltage to stabilize.
- Designed for 120V systems, it accommodates standard residential and RV electrical requirements.
- Combining mechanical and electrical capabilities, it ensures efficient power distribution and control.
- Versatile Power Transfer: This 30 Amp transfer switch seamlessly integrates with inverters, shore power, and generators for reliable electricity management.
- Can handle 2 sources of 30 amps at one time
- 30 amp Transfer Switch provides automatic power switching between two separate 120 volt AC input sources.
- Combining mechanical and electrical capabilities, it ensures efficient power distribution and control.
- One Year Warranty is Provided
- 【FUNCTION】: After starting the onboard generator or backup power source, power is automatically switched to AC appliances. Seamlessly integrates inverters, shore power, and generators for reliable power management
- 【MATERIAL】: Made of Plastic and Copper, it offers wear resistance, impact resistance, and low heat generation, making it suitable for diverse environments encountered during RV travel
- 【EASY INSTALLATION】: No rewiring required, pre-punched holes are provided for professional installation
- 【DELAY DESIGN】: Features a time delay of 20-30 seconds to allows the generator voltage to stabilize
- 【SAFETY INTERLOCK】: Combines mechanical and electrical functions to ensure efficient power distribution and control
- Versatile Compatibility: Handles up to two 30-amp power sources simultaneously, providing flexibility in power management.
- Easy Installation: Features knockouts that ensure a quick and professional installation process.
- Delay Switch for Generators: Includes a delay switch to ensure safe and smooth power transitions when using a generator.
- Built-in Protection: Safeguards connected devices by managing power transitions efficiently.
- Compact and Efficient: Compact dimensions (9.65”L x 7.28”W x 4.75”H) for easy integration into RVs, boats, and off-grid systems.
