Electrical shore power is a term used to describe the process of connecting a boat or other watercraft to an external electrical power source. This is typically done when the boat is docked at a marina or other facility, and allows the boat's electrical systems to be powered by the shore-side electrical grid instead of by its own batteries or generators. Electrical shore power is a convenient and efficient way to provide power to a boat, and can be used to run a variety of electrical appliances and systems, including lights, refrigerators, and air conditioning. Some common features of electrical shore 

power systems include: Shore power cables, Shore power connectors, Shore power inlets, Shore power panels.
