Phase Coloring

On a 120/240 three phase Delta system I like using Pink, Orange and Purple as the color code.

The reason I use these colors is because they explain what will happen should the 208 high leg get used to feed a 120 volt piece of equipment, POP.

Now doesn?t that make a lot more sense than some of them other color combinations that are being used around the world today?

Roger, I'm good with that. I worked on a motor this week that had 3 blue ungrounded conductors, and one had a little orange tape at the disconnect and in the motor head. I was merely stating how I LIKE to mark them. I believe I am partly to blame for making this "much ado about nothing"!

Hmmm... 208 versus 120 is 1.732 times greater potential to kill. Need I say more?

Okay, in the all-other-things-being-equal arena, yes, the higher the voltage, the worse the shock; simple Ohm's Law. However, every shock is different, and under the right conditions, even lower potential can kill. Some have survived shocks of many times the voltage that has killed others.

Treat it all as deadly, even when working on your car.

Is this another one of those "the purple tele-tubby is gay" statements?

Why yes it is....

Really I find it hazardous, as only one 28 sq mile city here does it, and makes it confusing for everyone else in the state who stick to the CEC/NEC. And for no other reason than to be different. It's not a POCO, or regional practice item. Whats worse is that purple often looks red when it fades....

Both 120 and 208 can kill.

Either will ruin your day if you short it out or otherwise have a problem.

We are not talking about a grounded conductor vs a ungrounded conductor.

What question were you answering?
