Extension cords @ dock
What are the normal "rules" / etiquette for using extension cords when at dock?
I do not have any connections on the boat for the heavy duty shore power cord. I have one battery that was used to run interior light (1) and running lights. The previous owner left some AC fans onboard so I presume he plugged an regular extension cord into a shore power pig tail adapter.
Is this an ok thing to do? We don't have anything planned other than A/C fans for sleeping.
