Go for your life.. but just a little advance warning: Try that down here and you'll end up on dry land.

Most of the world uses the IALA A standard. Red right returning to sea instead of the US centric IALA B red right returning to harbor.

At least the rest of the world finally got the US to paint all the black cans green.

And then there are the cardinal marks ...

Re: Yellow ground safety wire

"I needed to switch to using yellow for ground. This caused me substantial irritation, particularly as West Marine has far more ground stuff in black than in yellow,"

No, stop and think about it for a minute. The "safety" problem is that conventional black wires, wires not cables, could be DC grounds, DC negatives, or AC hots, and you've got no way to tell which is which by looking at it.

That's obviously not going to be the case with ground CABLES on a boat, as you're just not going to find individual AC *cables* in boat wiring. Maybe on ships, but not on recreational boats.

So if the stuff you're looking at in the chandlery is battery cables, forget about yellow, the black is perfectly good and safe.

When it comes to wires in a loom or harness or going to panel--that's something else again. (Usually "wire" means 10AWG or thinner, while "cable" means 8AWG or thicker.) If you see a budle of colored wires, 12-14AWG, and one of them is black...you have no idea what it is. If there's AC on the boat, it could very well be an AC hot line. That's why changing to red+yellow on new DC wiring becomes useful. Wiring, not cabling.

A wire is a single conductor. A cable is a number of individually insulated conductors tied together or (more commonly) covered with an additional layer of insulator. The genesis of "cable" is many components, thus mechanical cables (most wire rope counts), optical cables (multiple fibers in a sheath), and electrical cables (as above).

Open up your computer and you'll find ribbon cables with 10s of conductors only 24 AWG or smaller. The 12 or 14 AWG cables run all through your house or boat with hot, neutral, and ground for 117 VAC (in the US) are, well, cables. A cable is a collection of wires (electrically) and has nothing to do with size.

Re: Yellow ground safety wire

"A wire is a single conductor. "
That's a different use and meaning of the word. Or have you never bought "stranded wire" as opposed to "solid wire" ?

Auto stores, battery stores, hardware stores...and it isn't just a New England thing. Ask for "cable" and they reach for the heavy stuff. Ask for wire, and they reach for different spools. Maybe that's wrong and corrupt but then again...so are so many fun things.

Re: Yellow ground safety wire

Gentlemen. I'm a novice at this stuff (and tomorrow after I take the ham test I'll be on the path to official geekdom), so can you help me out here?

I downloaded the ABYC electrical standards. But it appears that the ABYC standards differ from the rest of the US standards? Am I correct? And, it appears that the two of you are using the same name for two different things (i.e., wire). Confusing. Is this like the age-old line vs. rope argument?

Is there a single resource that you can recommend that I add to my boating library?
