With the new boat, we plan on staying at some transient docks and there are electrical hook ups. I dont have one of them plug in,s on my boat. With the purchace of a few items which require power,I would like to hook up something that would allow me to use the power supplied at the dock and not my cranking battery. I have made up the power cord for the hook up.30 amp 125 volt.(not to worry,it was made waterproof by our resident electrician). What else do I need to do so I can run the power through the boat ,without using up my cranking battery, like I said.
Thanks
