Three Plug Tips
 Keep shore-power cables stored in a designated locker, away from moisture and cleaning supplies. If leaving at a dockside hanger, disconnect the plug and keep it facing down to prevent water intrusion. Dockside breakers should be turned off when not in use.
 Dockside power sources vary. Identify the power source(s) at your favored destinations, and buy the corresponding pigtail adapters to keep things running smoothly. A 30A locking receptacle is the norm at most U.S. marinas.
 Avoid tight coils; they generate heat. Likewise avoid pinching cable under a door or hatch. Make sure plugs and connectors are secured in their full, locked positions. Tug cords to verify.
