I'm introducing a quick reference quide the size of a credit card,laminated,two sided. With 120/208-240 colors and on the other side 277/480 colors with the circuit # next to the color...ex..

1 Black 2
3 Red 4
5 Blue 6

etc.

And code references at bottom of card. I had this in mind for the upcoming apprentices, for when a journeyman tells them to set up the wire for a pull he know's what colors are for what circuit #

Appreciate you feedback...Thanks.

Steve :grin:

Well, there is no NEC requirement for these colors to be used for these applications, so I hope you are going to make these cards available for free. :)

Yep, and welcome Dana.

I teach all my guys that any multiple of 6 and the number under that is a C phase. So count up 1 or 2 for A phase and count down 1 or 2 for B phase. Simple, no card required.

I made of those quickee reference cards awhile back...colors and conduit fill for 12/10's as well as derating for CCC.


Came in real handy on the job.

Teach them ROTATION, ROTATION, ROATION and consistency in their installation of conductors and what ever color code is prevalent in the are they work in.

Brian,

How does it not? It puts the conductors on the correct phase.

I worked on a small factory one time where we all had that line from the holiday poem....

"The phase rotation was correct, we were lead, as multiples of six danced in our heads....." (My apologies to Clement Moore)

Then the POCO got the rotation wrong in the transformer, so the entire building has 'reverse' rotation. It's that way to this day.

Someone please explain the multiples of 6 thing. 34 years in the trade and this thread is the first I've heard of it.

I guess that's why I hang around places like this.:smile:

On three-phase systems, the "C" phase will always be on a breaker numbered in a multiple of 6. 6,12,18,24,30,36, and 42 are all the "C" phase.

Subtract 1, and you're still on the "C" phase.

Subtract 2 or 3, and you're on the "B" phase.

Add 1 or 2, and you're on the "A" phase.



Logic goes like this:

What phase is circuit #27 on?

30 = C
subtract 3, you're on B.
Ergo, use Red or Orange.


Try 19
C=18
Add 1, you're on "A"
Black or Brown, then

That's a printed version. I never had a CD of it. Must be some real powerful virus, huh?:grin:
