Air Terminal Types — Which One Is Best for RV Protection?

Understanding Air Terminal Types

When it comes to protecting RVs from lightning and voltage spikes, choosing the right air terminal type is crucial. There are several types of air terminals available, but only a few are suitable for RVs. A Surge Arrestor, also known as a SPD or Surge Protective Device, is a type of air terminal specifically designed to protect electrical systems from voltage spikes and surges.

Surge Arrestor Selection and Installation

When selecting a Surge Arrestor, consider the following factors: the device’s voltage rating, which should match or exceed the RV’s electrical system voltage; the device’s current rating, which should be higher than the maximum current expected from a lightning strike; and the device’s temperature rating, which should be suitable for the RV’s operating environment. Install the Surge Arrestor at the point of entry for the solar panel’s electrical connections, typically at the RV’s electrical panel or at the point where the solar panel’s wiring enters the RV. Ensure the Surge Arrestor is properly grounded and securely fastened to the RV’s chassis.

Lightning Protection Best Practices

To ensure maximum protection for the RV’s electrical system, follow these best practices: install a Surge Arrestor at the point of entry for the solar panel’s electrical connections; use a surge-protected cord or cable to connect the solar panel to the RV’s electrical system; and ensure the RV’s electrical system is properly grounded and bonded. By following these guidelines and selecting the right air terminal type, RV owners can protect their electrical systems from lightning and voltage spikes, reducing the risk of damage and electrical shock.
