What do the letters NEC stand for? List the color scheme required by the NEC to keep track of hot, neutral and safety grounds in the circuit? What is the neutral conductor called in the NEC? Discuss/describe the safety ground. Include what is its purpose, how does it provide its function, the color of the wire and what should be connected to it. Complete the schematic shown below of a light being controlled by four switches. Power comes in from the left and Romex (NM) cable is run to each box consecutively from left to right. All conductors in any cable selected must be used. Indicate the type of switch in the blank provided. Show connection points on each switch with heavy dots. Put a small "c" beside the common terminal on any 3-way switches. Do not show safety ground
