Using this Camco marine extension cord is easy. First, make sure your boat's power requirements match the cord's 50 - amp rating. Then, connect the male end to the power outlet and the female end to your boat. The threaded locking rings should be tightened well to ensure a weatherproof connection. When using it outdoors, be aware that although it's protected from moisture, it's best to avoid submerging it in water. For storage, use the adjustable cord organizer to neatly coil the cord. The carrying strap handle makes it simple to move around. After each use, check the cord for any signs of damage, like cuts or frays. If you notice any issues, stop using the cord and contact Camco for assistance. Keep the cord in a dry place when not in use to extend its lifespan. Remember, it comes with a 12 - month warranty, so if it has any defects in normal use, you're covered.
