Article 250 · Texas pack
Grounding and bonding, Article 250
Article 250 is the long chapter. The misses come from treating every green or bare wire as the same thing. Split the electrode, the bond, and the fault path before you answer.
- The grounding electrode system connects the system to the earth. The main bonding jumper ties the grounded conductor to the equipment grounding path at the service. The equipment grounding conductor is the fault-current path back to that point.
- Free items describe one of those jobs in a short jobsite sentence. They cite Article 250. They do not reprint the section.
- If grounding is under 70% on the free practice test, this topic is the next sitting. It is also one of the slower lookups, so tab the parts you keep swapping.
