Quick Answer
To protect RVs from lightning, consider using a Faraday cage, surge protectors, and a grounding system. A Faraday cage acts as a conductive shield, while surge protectors safeguard against voltage spikes. A grounding system helps to dissipate electrical discharge.
Installing a Faraday Cage
A Faraday cage is an effective method for protecting RVs from lightning. It involves wrapping the RV with conductive material, such as aluminum mesh or copper, to create a conductive shield. This shield attracts and disperses electrical charge, protecting the RV’s electronics. For RVs with a rounded or curved shape, consider using a mesh with a diameter of at least 3/16 inches to ensure effective shielding.
Grounding and Surge Protection
A grounding system is crucial for safely dissipating electrical discharge. The system should consist of a grounding rod, a bonding strap, and a grounding clamp. The rod should be at least 8 feet long and 3/8 inches in diameter, driven into the ground. The bonding strap connects the RV’s metal components to the grounding rod, while the grounding clamp secures the bonding strap. Surge protectors, such as MOVs (Metal Oxide Varistors) or gas discharge tubes, can be installed on the RV’s electrical panel to absorb voltage spikes. Consider using a 2500-amp, 3-phase surge protector for maximum protection.
Additional Considerations
When selecting a grounding system, consider the RV’s size, shape, and location. For RVs with a metal roof, consider using a grounding rod with a built-in bonding strap to simplify the installation process. Additionally, ensure that the grounding system is regularly inspected and maintained to ensure optimal performance. It’s also essential to consult local building codes and regulations when designing and installing a grounding system for your RV.
