Quick Answer
Protect your RV from lightning by investing in a good quality lightning arrestor, installing a grounding system, and using surge protectors for sensitive electronics.
Grounding and Lightning Arrestors
A lightning arrestor is a crucial component in protecting your RV from lightning strikes. It should be installed on the RV’s roof, typically within 3 feet of the highest point, and connected to a grounding system. This system should include a minimum of 8-foot-long grounding cables and 10 AWG copper wire, buried at least 12 inches underground to prevent damage from lightning strikes. A grounding rod with a resistance of 10 ohms or less is recommended.
Surge Protection for Electronics
Sensitive electronics such as your RV’s computer and appliances can be damaged by power surges caused by lightning strikes. Installing surge protectors, such as whole-house surge protectors or point-of-use surge protectors, can help safeguard your electronics from damage. These devices can handle power surges of up to 6,000 amps and can be installed in the RV’s electrical panel or near sensitive equipment.
Safety Precautions
When camping in areas prone to lightning strikes, it’s essential to prioritize your safety and that of others. Look for signs of a lightning storm, such as darkening skies, increasing wind, and thunder. If a storm is approaching, unplug sensitive electronics, secure outdoor furniture and decorations, and seek shelter. Avoid using water, taking showers, or using sinks during a lightning storm, as water is an excellent conductor of electricity. If you’re unable to find shelter, consider moving to a nearby building or vehicle with a metal roof.
