A
2
Q
When using Table 16, what are the only two situations when your bonding wire is sized off of the largest ungrounded conductor?
A
For the service raceway bonding conductor and for voltage drop
3
Q
What are the advantages of an impedance grounded system?
A
Rule 10-302 (App B.)
- Decreases the level of ground fault current
- Mitigates equipment damage and reduces loss of production
- limits the voltage rise of other phases
- stabilizes the system voltage to ground
