| Essential Question | Level of Thinking |
| How are system grounding, equipment grounding (bonding - protectiveearthing), and common mode / EMI grounding different and related? | |
| What are the principal features and methods of implementation of ungrounded systems, high-resistance grounded systems, and solidly grounded systems? | |
| What grounding methods are appropriate for Primary buses, distribution buses, secondary buses, and special buses? | |
| How does one determine the required resistance of a neutral grounding resistor? | |
| What are the advantages and disadvantages of a grounding bus? | |
