For wires that will be 120, 208 or 240 volts, the following wiring color standards are used. It is important to note that with this type of wiring, there are multiple phases in place, each of which will get its own color wire to make it clear what it is for those working on it.
Electrode - Wikipedia
An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). The word was coined by William Whewell at the request of the scientist Michael Faraday from two Greek words: elektron, meaning aer (from which the word electricity is derived), and hodos, a way.
