Question
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.Explanation / Answer
Solution:
1. NEC stand for National Electrical Code. It is a regional standard that is adoptable for the safe installation of electrical wiring and equipment. It is used in United States and is part of the National Fire Codes series published by the National Fire Protection Association(NFPA).
The color scheme that is required by the NEC to keep track of the hot,neutral and safety grounds in the circuit are as follows:
Hot: Red, Blak,Blue, Orange, Brown and Yellow (Depends on circuit voltage and phase system used)
Neutral: White or Gray
Safety grounds: Green or green stripes
Neutral conductor is defined as The conductor that is connected to the neutral point of the system that is meant to carry current under norma conditions or it can also be defined a a common point where the three-phae conductors of the wye system are connected to both the grounding electrode and the grounding-electrode conductor.
