The size of the ground wire for a 200 amp service depends on several factors, including local electrical codes, permits, and the type of wire used. Here are some of the answers found in the search results:
- According to Table 250.122 in the NEC, for a feeder with a 200A maximum breaker ahead of it, it requires a #6 copper ground wire.
- 250.66(A) says the grounding electrode to a single or multiple rods shall not be required to be larger than a #6 copper wire.
- Grounding Electrode Conductor (GEC) for 200A is required to be 4 AWG copper.
- For 200 amp service, you would need at least 3/0 AWG copper wire or 4/0 AWG aluminum or aluminum copper-clad wire.
- Youll need a 4 AWG copper wire or a 2 AWG aluminum wire for the grounding wire conductor.
Based on the above information, the size of the ground wire for a 200 amp service can range from #6 copper to 4 AWG copper or 2 AWG aluminum. It is important to check local electrical codes and permits to ensure compliance.
