400 amp service
I may be installing a geothermal unit in new construction. I was told I will need 400amp service.
1. How many hot and neutral wire come from the utility company.
2. Will it be single or three phase.
3. Will I need 1-400 amp breaker box or 2-200 amp boxes.
4. Is there a lot of cost associated with a 400 amp service compared to a 200 amp service.
Any help in this would be appreciated or If you have a link to good info.
