lol.....Love 3 phase questions....

What if they have a (4) Wire High Leg Delta...lol........then what colors...should they see...I wont tell...

Also...what is the proper PHASE arrangement of this panel in regards to the terminations....

Sorry Gerry....I simply can't resist sometimes.....Good QOD

Maybe If I have time....at the end I can explain about problems in commercial with panel upgrades on 3 phase versus todays arrangement and older arrangements.....if anyone cares to listen later...lol

[Paul W. Abernathy]

OK..........QOD...stop and think......3 phase..we are not bringing into the equation the Grounded Conductors identification in this question....before you answer it....stop....drop and roll...I mean THINK about it...

Neutral = White.

Mr Guru....?

Aren't the only colors mandatory by code are green /
green with yellow tracer for grounds, or grounding conductors and white or natural gray
for neutrals, or grounded conductors. orange for high leg?

[Paul W. Abernathy]

Yeppers........I was only shooting for the Orange...lol....the colors Gerry posted are acceptacle industry color markings.....now on branch circuits of multiple voltage systems you have to mandatory identify ungrounded phases...but again ....I dont want any brains to explode of this.

Hi to all,

I thought that I had posted a fairly easy question, but I am afraid I am not going to understand the answer myself

All that stuff about middle leg Beta and stuff, I am getting one of my headaches, I think I'll lie down.

Paul, you own it

That'll teach you to mess with QOD

You stick to arguing over CMI and leave the serious stuff to professionals

Regards

Gerry

One of the conductors on a 3 phase [Grounded B-Phase (Corner-grounded Delta) System] could be white or gray if the system was as follows:

http://ecatalog.squared.com/catalog/...3%2003-10.html

Specific colors for conductors are assigned to be green, green with yellow, white, gray, etc., and some special colors such as as light blue, yellow, and for ceiling heat, brown, orange, and yellow too.

See the NEC Index under "Color Code" if interested.
