Boat Wiring

[Ducati]

Last fall just before haul-out I took photos of all of the wiring connections for the mast.
I looks like an octopus on crack. Anyhow good thing I had the photos because I was able to get it right the first time. My real issue is that I have no idea what I'm hooking up and was wondering how I go about learning more about where all of the red, black and white wires go to and what they do. I'm not looking to become certified in marine electronics just looking to get a better understanding (the big picture) of how things work.

Post the picture and some of us will be glad to help and also give you some ideas like maybe a terminal strip to make it easier for the next time

Alternating Current: Wiring Color Codes
I strongly recommend that unless you have experience or training working with AC electrical systems, that you hire an electrician. AC is deadly!
Black: Hot: An ungrounded current carrying conductor. This is the hot side of the system. Do not touch! You will get zapped!

White: Shore Grounded Neutral A current carrying conductor maintained at ground (Earth) potential. Do not touch! You will get zapped!

Green or Green with Yellow Stripe: Grounding Conductor. Used as a path to ground if there is a ground fault in the system Do not cut or disconnect!
Red: Hot: An ungrounded current carrying conductor in 120/240 volt systems. Do not touch! You will get zapped!

And of course, don't forget to cut off the power before you attempt to do any electric work...
