Frequently Asked Questions

What is the maximum amperage I can safely draw through this adapter?

The maximum safe amperage is 15 amps, determined by the female end rating. Never exceed this limit to prevent overheating and potential fire hazards. The 30-amp male end connects to the dock, but the adapter is limited by its lowest-rated component.

Can this adapter be used in wet marine environments?

Does this adapter provide GFCI protection?

No, this adapter does not include GFCI protection. You must ensure that GFCI protection is provided at the source (dock pedestal or main panel) as required by marine electrical codes and safety standards.

What types of equipment can I connect with this adapter?

You can connect any 15-amp or 20-amp equipment with standard straight blade plugs, including power tools, battery chargers, work lights, small air compressors, and portable marine maintenance equipment. Always verify the equipment draws 15 amps or less.

Is this adapter suitable for permanent installation?
