Trying to figure out what's going on with the wiring
on the boat I just bought...
I'm a total non-technical newbie to electrical
issues and wiring
so please be patient with me. I'll be as descriptive as I can be and hope someone can walk me through rewiring this mess.
i have an electrical control panel
that is dedicated to 110v wiring. along side it (on the back is another, separate panel).
The top switch is labeled 'Main' and has the black wire from the shore power
wired to it. Across from this, the white wire is connected to the secondary panel. The green wire is hanging loose. This concerns me.
The other wiring appears to be ok until we get to the 'Inverter' switch. This appears to be the main switch for 110v coming FROM the inverter
. This has a wire with a 3 prong plug
on the end that is cut to length for fitting into the plug
on the side of the inverter
. One wire to the switch panel, two other wires to the secondary panel. However, the wire to the switch panel is white - but I suspect there are two whites and one green on this wire.
Below that is another switch labeled 10A Port. This appears to be the 110v wiring for the port side of the boat. This wire has the green and white connected to the secondary panel, but the black wire is not connected to the main switch panel.
Along one side of the switch panel is single
(black) wires coming in. Along the other side is a series of short black wires connected to other switches on the same panel - like jumpers.
I have a lot of questions and don't even know where to start.
First, is there any reason to have the disconnected wires.
What is the function of the smaller secondary panel with white and green wires? Is it just a ground?
What is the purpose of the black 'jumper' wires on the other side of the panel?
What 'typically' are the functions of white/green/black wires? ie: which is hot, ground etc.
Sorry for all the questions and absolute 'newbie' descriptions but I need to learn what this stuff does and how it works so that I can fix it now and in the future (if necessary).
Thanks in advance to anyone who dares to help
