Green Wire as Phase Wire?

[tdaug53]

We are installing a printing press from China and they are using Yellow-Green-Red as the phase wires for 380 volt 3 phase. There is green wire through out the machine as a phase wire. What is everyone's thoughts on this?

It is what it is. What happens inside the machine is not under the jurisdiction of the NEC.

I would have to agree with Larry. Does the machine have a third party cert? Being out of China, I would doubt it.

I would really doubt that it has a NRTL listing.

I also argee that the wiring within the equipment would not be subject to the NEC.

As long as you only have to make connections to L1-L2-L3 it really wouldn't make a difference what color the internal wiring was.

Treat it just like trips to Vegas.
What happens in the machine stays in the machine.

An electrician died from just this issue of Chinas color code.
Some states will not allow non-listed equipment.
90.7 tells us the internal wiring is not subject to inspection, if it has been listed by a qualifed testing laboratory.
I recommend you discuss this with managment and get an answer in writing.

It just so happens to be a printing machine.

Re-identify it with colored, except green, white or gray, phase tape.

20 years ago there were depression era buildings in NYC that had 208Y/120 Black/Red/Green/White feeders. I wish that I had a photo. Hopefully by now they've all been removed.

I wired a machine from Japan back in the 80's that used red white and blue for their wire colors.

Many US utilities use that same color scheme.

Phase rotation meters typically have red whit and blue leads.

Cost me a pair of dikes to find out that green used to be a nongrounded conductor.:smile: It was funnier when it happend to my brother.:grin:

Good thing electrons are color-blind!

About 6 month ago I installed a coater made in China and sounds like the same crew did the install going to have to check this out.

Isn't green used as a "hot" conductor in traffic signal controllers?

Without UL it fails here.

Yes, but only for the grounding lights. :grin:

The amber uses 277v, and the red is 120v.
