Open up an industrial control box, inside will be just a few colours with most as Red or Black. If the electrician has been helpful there will be small white clips on each end of the wires with the code being the same each end and a list of codes inside the panel door.when I was younger (in the 80 's !) I was cheap and had the opportunity of 50 yards of red wire , which I used to make a new wiring for my cdo , and it works for me , but as I had done it during few days , then I need a multimeter to know where I was the previous days to continue my job .......
