  • Dirty terminals are the second most significant cause of connection failure.
  • The most significant cause of electrical failure in caravans and trailers is oxidisation inside the trailer plug.

It is essential to keep electrical connections dry otherwise they will fail.

Electrical flashing is caused by dirt and humidity. Electricity tracks across the wet dust, causing a flash. As a result of the flash, there is an associated explosion.

Electrical accidents are significantly reduced with plug covers.

Prevent electricity to flow between terminals via a shroud or barrier.

The locking tabs ensure a safe and reliable connection for towing, battery charging, and marine and industrial OEM applications.

Are Anderson Plug Covers Waterproof?

All-size plug covers help prevent the ingress of water and dust but are not waterproof or submersible.

How is water conductive?

Electricity passes along a stream of water from point A to point B. Electricity passes better through water with salt content.

Water provides a path between active and neutral conductors, causing tracking. Tracking causes power to be used, flattening the battery even when not connected to the battery.

Did you know that salt water is more conductive than freshwater?

Yes, the ions in the saltwater make it easier for electricity to pass between molecules.
