In marine electrical system there is a so called: "SHORE POWER"?

Question

i know marine electrical engineers or marine electricians do know more about this.. can someone please help me? i tried to search at Google but it gives a false information.. any good answers? i will give ten points.. Promise..

-thanks in advance!

Answer 1

Power you plug into when you are docked.  It can be different voltages and amperage.  For example, my boat's shore power hookup is 120V 30AMP.  This charges my batteries, Powers my fridge, microwave, stove, water heater, etc. When I'm at sea the batteries or generator run these.

Answer 2

Some boats are equipped for AC power that can come from the dock on a large yellow cord. This can be 15, 20, 30 amp for smaller boats and multiples of that for larger boats. Smaller boats do not have AC power inside but rely totally on batteries.

Answer 3

On boats with AC electrical systems there is usually a switch for "ship" and "shore" power.  Ship power would be electricity coming from an onboard source (battery network, generator/genset) while shore power is power that comes from off of the ship (plugging in to an outlet while docked).

Answer 4

When at sea sailboats boats run off batteries (12v or 24v are the commonest). These are charged at sea only when the engine (or dedicated generator) is running. Motorboats use batteries too for when they are at anchor (though they too usually have generators). Since they only move when the engines are running the batteries are charged almost all the time. 220v/240v (or 110v) A/C power is available at sea, either via the dedicated generator or via a DC-AC inverter.

When we put into a marina or port they are often equipped with boxes at each mooring which we can plug a 220v/240v (or, I guess 110v in the USA) plug into to bring mains power aboard. Then  we charge the batteries with a mains battery charger and use the shore power for running most things on the boat.

Answer 5

shore power simply refers to a circuit set up (inverters etc) which allows you to plug into 110 volt shore power while docked

Answer 6

when you dock, you plug into shore power for electricity.

Answer 7

Yup...like they all said. Basically you hook up an extension cord from your boat to the dock. There should be provisions for the connection at either end to be secure...ie: twistlock (hubbell) ends...a GFCI Breaker dockside and adequate fuses boatside immediately after the shorepower comes into the boat. From this point you have distribution within the boat directly for 110 to 125 V appliances or through an inverter or step-down transformer for 12,24, or 36 V appliances.

It doesn't magically charge batteries...there has to be a charger inline.

Answer 8

im not shore (teehee) what your specific question is but shore power is what you hook your ship up to at the dock so you can still have power and not have to run  your engines or generators. basically a 220v extention cord that plugs into your vessel.

Answer 9

SHORE POWER means, power taken from shore

Answer 10

Think they have covered it all so far. Was there a certain question you wanted to ask regards hook up? if so mail me and I'll ask hubby tonight . We do have a boat but he would know the answers to your question hope I can help

just read my answer, no I wasnt being rude  he may be able to help!

Answer 11

It means you can plug into the mains power on the wharf or shore.
