Wiring Nightmares

One of the last places you would ever want a fire is out at sea.  That is why wiring is so important and often times completely overlooked.  Wiring is not always difficult but it is tedious to do it right.  If you plan to have wiring done on your boat or you plan to do it yourself there are a couple of things you should understand.  For one there is a huge difference between marine electrical systems and electrical components you would see in a house.  This being said do not go to your local hardware store and pick up some house wiring and electrical connectors.  For example wiring you see in your house is considered a two conduit because the ground wire has no insulation however on the marine side of this the ground wire is in a green insulator making it a 3 conduit wire.  This insulation helps to prevent corrosion and issues down the road. Here are some helpful hints whether you are doing it yourself or just want a better understanding.  When selecting electrical components to go into your boat make sure the wires you are running are not only marine wire but also are the correct AWG for the load.  Do not use a house AC panel for your AC and DC wiring get the proper panel with the correct number of breakers that you need.  Always use heat shrink connectors to prevent corrosion and damage.  Never use wire nuts or those splice connectors that cut through the insulator.  Saving a couple of dollars in the short run is never worth what it may cost you if you have a fire out at sea…
