Title: Identify the functions, operation, and characteristics of grounding systems.
Course: Building Trades II (17009-II) > Section: ELECTRICITY: Applying Basic Electrical Wiring

Based on the latest NEC, identification should include

- explaining the purpose of grounding
- distinguishing between a short circuit and a ground fault
- defining a ground circuit
- explaining the requirements for physical protection for the grounding electrode conductor
- defining made electrodes
- defining the use of a grounding electrode system
- explaining the use of a main bonding jumper
- explaining the purpose of the grounded conductor
- explaining the requirements for grounding more than one building
- explaining the requirements for grounding subpanels
- describing concrete-encased grounding electrodes (i.e., Ufer ground).

IRC: Chapters 34 through 43 identify all electrical components related to residential construction along with their use and installation. These chapters include general requirements, electrical services, branch circuits and feeders, wiring methods, power and lighting distribution, devices and luminaries, appliance installation, swimming pools and Class 2 remote controls, and power-limited controls.

Process/Skill Questions:

- In which article in the NEC would one find grounding systems?
- What is a man-made grounding system?
- Why is grounding important?
