Can I use this wire?

Postby DrBryanJ » Mon Sep 07, 2015 3:26 am

My neighbor works for PSE&G. He has offered me wire they use for outdoor applications in any color or gauge I need. Can I use it for my boat?

Marine wire is subject to vibration and moisture. It is multi-stranded and each strand is tinned.

If this wire is solid core don't us it. The vibration could fatigue it and cause it to fail. If it is multi-strand and you do a good job sealing all your connection and the boat is stored dry, it could give you years of service.

Thanks Bill. I'm not sure if it is solid or multistranded. He is going to get me a sample to check out.

Spoke to my neighbor. He says the wire is all multi-strand. Should be good to go. Should I stick to the recommended colors if he can get them (don't want to be a pest to him) or is red and black okay?

Go proper color coded if possible, it makes life a lot easier in the long run, from installing to troubleshooting.
This is my first, last and only boat build.

Since you making a "home made" boat you don't really have to follow the rules for wire colours.

But, if you try and stick to at least the main colours it could save a headache later on, particularly if you don't remember using brown in place of black etc. or someone else attempts to figure out what you have wired where.

Just one other note from me. In newer boats the 12 volt black wire has been replaced with a yellow one.

On many cruisers there is both 12 volt and 110 volts systems so to prevent a potentially dangerous "oops", on 12 volt systems the red wire is "hot" and the yellow is now the return so not to get mixed up with a 110 volt "black hot wire".

On 110 volt ac, black is hot, white is neutral, and green or bare copper is ground.

From memory... :?
On dc systems, Red is always hot. Black or yellow is negative. Nav. lights are grey. Bilge pumps/blowers and water pumps are brown. Auxiliary equipment is orange. Interior lights are blue. Earth ground is green.

This really helps if you pull your wiring ahead of time and when you are trouble shooting a problem.
