Re: A slight diversion from chuck issues: 24v DC motor wire code

Had a solar hot water heater controller like that on my house in Las Vegas in the early 80's. That company didn't another dime from me.? A few years ago one of the industrial washing machines I was working on had a small electrical fire that damaged? a bunch of the wiring. All the wire in that machine was red, but there were number tags on all the wires. It took me most of a week, but I completely rewired the machine. Marking on the wires & connectors makes the difference.? A lot of years ago, I built my first computer from articles in Radio Electronics magazine.? It used wire-wrap sockets, and I could only afford one roll of the wire, at $25 per. First-time power up let the magic smoke out of some very expensive chips. They? call that "pound wise, penny foolish." It would have taken a couple more months to get more colors of wire but I didn't want to wait any longer.? It's easier do it right than do it again. See my first aphorism. :) William R. Meyers, MSgt, USAF(Ret.) Aphorisms to live by: Good judgement comes from experience. Experience comes from bad judgement.? SEMPER GUMBY! Physics doesn't care about your schedule. The only reason I know anything is because I've done it wrong enough times to START to know better

You can always sleeve the leads of your motor for safety sake
even with heatshrink.? I've done it before on gear that I wanted to make MORE fool proof.
I once worked on a dental chair that the manufacturer wired
everything in the same gauge white wire.? That was years ago & that manufacturer did it to stop anyone
servicing their gear.? They would probably not be game to go quite so far now days with wiring for safety reasons but I have seen newer gear that has all the IC markings removed.

The problem is the same as that with thread sizes ¨C there are simply too many of them to be uniform everywhere. ? Even just In the US, for house wiring (120 / 240 volts), ground is bare or green, hot is black, and neutral is white (or gray).? If the other phase of the hot is in the same conduit, it may be any other color, but is usually red.? For industrial three-phase wiring, the ¡°standard¡± colors will vary with the voltage, and whether the distribution is delta or wye. ? Of course, what is important is that the colors (or thread sizes) used throughout the job are uniform and that everyone working on the job understands exactly what ¡°standard¡± is being used. ?
