On a 120/240Volt single phase system is:
Black = 1st phase
Red = 2nd phase
White = neutral
Green or Bare = ground
3 phase is the same with the third phase being blue.

Tips for a great answer:
Answer> Manuals: If you want FREE manuals for your device, you must go directly to the maker of your hardware device. Look for their SUPPORT (Drivers and Downloads) and input the required data such as the Make, Mod. of the device in question. They will then take you to the proper section where Drivers and Manuals are located. Here you simply select the option you want to download and install your drivers or open a manual. Manuals often come down in PDF format and require Adobe Reader. Get Reader form http://www.Adobe.com .
