12v wires

[dccruiser]

Personally i have always wired my boats circuits red for positive , black for negative, then whipped all the reds and blacks together in the back of the panel to form two looms, then just used cable idents for the individual circuits.

Why? It was correct.

Sudden doubts that I might be wrong when my whole being told me that I was right. DIN versus BS standards etc. You know how it is, you have to be 150% correct on here

I used red and black for 12V and Brown, Blue and green with yellow trace for 240V for all circuits. I also added cable numbers on each end of the cable and recorded these on the circuit diagram. I did consider using wires with trace colours (I work in an industry where I have access to the full range) however I stayed with red / black since it meant that anyone else could debug it if I sold the boat. If I need to sort out a wire from a bundle I can use a signal tracer.

 

Slightly off topic.

 

a very good 'signal tracer ' can be bought from £shop/ cheap shops. It looks like a screwdriver with batterys & if power is on the cable it, the screwdriver, will light up.

 

It will also do presence of voltage (DC & 70 to 250AC), continuity, find cables in walls/behind panels,ground faults, test diodes/transistors, microwave leakage & more.

 

No commercial connections, just a magic bit of cheap kit & you can have one on the boat one in the workshop etc.
