Too bad that OSHA or one of the several other groups that
inspect plants for safety has not stepped in and said something
about that.

Too bad the company was not smart to specify the standards they
wanted when they ordered the equipment.

They may not have had much choice. I don't know about the offical
standards, but in the US for years it was red for off or stop and
green for on or run.

Then the European standards at some time was the opposit. When the
equipment was shipped in from Europe it came the their standards.
Doubt the company would have had much say.

Most of the large equipment was ran on the US standard of 480 volts 3
phase. We got in some of the European equipment in a very large plant
addition and it was 380 volts (think that is it, but could be off a
few volts) three phase. I was on the checkout crew after the
construction company finished installing it. No one told us about
the 380 volt equipment. As part of the check out was to calibrate
some heaters we could not get the controlers to put out 480 volts
like the other parts of the plant. Measured the in comming and found
out it was 380. Just love it when the 'standard' changes and no one
is told about it.



The company placing the order can specify what colors will be what.
Put it in the Specs.
