It is a premium investment into the longevity and safety of your RV’s electrical system.
Living full-time in my RV, I’ve experienced firsthand the anxiety of unreliable campground power. Power surges, open grounds, and miswired pedestals are real threats that can fry sensitive electronics and appliances. I needed a robust solution that would automatically protect my RV and provide a seamless transition between power sources.
The Southwire unit arrived securely packaged, and my initial impression was that this is a serious piece of equipment. The build quality feels incredibly solid, and the weight suggests robust internal components. It’s a far cry from some of the lighter, more plastic-heavy transfer switches I’ve seen.
I considered the Progressive Industries EMS-HW50C and the Hughes Autoformers Power Watchdog EPO, both excellent surge protectors, but neither offers the automatic transfer switch functionality. For me, the Southwire 41390-RVC Surge Guard Rvc Compatible Automatic Transfer Switch 120/240V 90A won out because it combined surge protection with the convenience of automatic switching, providing a comprehensive power management solution. I was excited to finally have a ‘set it and forget it’ solution.
Real-World Testing: Putting Southwire 41390-RVC Surge Guard Rvc Compatible Automatic Transfer Switch 120/240V 90A to the Test
First Use Experience
My first real test of the Southwire 41390-RVC Surge Guard Rvc Compatible Automatic Transfer Switch 120/240V 90A came during a stay at a rural campground in the Ozark Mountains. The campground’s electrical infrastructure was clearly dated, and voltage fluctuations were common. Installation was straightforward, guided by clear instructions, though professional installation is highly recommended for anyone not comfortable working with high-voltage electrical systems.
During a particularly heavy thunderstorm, the campground experienced a brief power outage followed by a surge. The Southwire unit immediately cut power, protecting my RV’s electronics. It then automatically switched to my generator after the pre-programmed delay, restoring power within seconds. The peace of mind knowing my RV was protected was worth the investment alone.
The switch operated flawlessly, even in the humid and occasionally dusty environment. It was so simple to use that it almost fades into the background – exactly what you want from an automatic transfer switch. There were no unexpected issues during the first use.
Extended Use & Reliability
After six months of continuous use, the Southwire 41390-RVC Surge Guard Rvc Compatible Automatic Transfer Switch 120/240V 90A continues to perform admirably. There are no signs of wear or tear on the exterior housing, and the internal components appear to be functioning perfectly. The transfer switch has weathered everything from scorching desert heat to sub-freezing mountain temperatures.
Maintenance is minimal; I periodically inspect the wiring connections and clean any accumulated dust or debris. This is very straightforward. The Southwire unit has far exceeded my expectations. I previously used a manual transfer switch and a separate surge protector, a system that was both cumbersome and less reliable.
Breaking Down the Features of Southwire 41390-RVC Surge Guard Rvc Compatible Automatic Transfer Switch 120/240V 90A
Specifications
- Electrical Rating: 120/240V, 90A. This high amperage rating ensures compatibility with even the most demanding RV electrical systems.
- Frequency: 60Hz. This is the standard electrical frequency in North America.
- Joules: 3350. A high joule rating indicates robust surge protection, capable of absorbing significant electrical spikes.
- RVC Compatible: This allows for seamless integration with RV-C systems, displaying voltage, current, and fault conditions on a compatible display. This provides real-time monitoring of your electrical system.
- Full RV Protection: The unit protects against power surges, open ground, open neutral, low (132V) voltage, reverse polarity, miswired pedestal, and high and low frequency issues. This comprehensive protection safeguards your RV’s electrical components from a wide range of potential problems.
- 95A FLA Mechanical Interlocking Contactors: These heavy-duty contactors ensure safe and reliable switching between power sources. The mechanical interlocking prevents the simultaneous connection of shore and generator power, preventing potentially dangerous backfeeding.
- Automatic Transfer: Automatically switches to generator power when shore power is unavailable (after a 30-second delay in generator mode). When both shore and generator power are available, the generator dominates after a 30-second delay. Once the generator shuts down, shore power activates after a 3-second delay. This provides a seamless power transition without manual intervention.
- UL Approved: UL1008 full transfer switch rating, UL/CUL listed. This certification ensures that the product meets stringent safety standards.
