How does one service, one meter feeding two main panels?
A residence with a 200 amp underground service to a meter, then two 100 amp SEU cables tied together on the load side lugs going into the house to two separate 100 main breaker load centers right next to each other. Both panels have their neutrals and grounds bonded together.
Can a house have more than one service entry feed?
Building code says you can only have one service entry feed to a residential house, but if your main panel is outside in the yard this does not by the letter of the law contravene this rule because your main power cutoff is the switch in your yard.
Can you run two separate feeds off of your 200 amp service?
You will need (may already have) a main breaker box next to the service, with separate main breakers for the barn and the house – maybe 100A each, maybe 50 and 150 or 75 and 125 – whatever suits your load split. In most code areas you CANNOT double-tap both demands off one 200A breaker by tying them into a bus bar that ties into the breaker.
Do you need two main service panels in a house?
A large home with many circuits and many permanently-wired appliances may require two (or more) main service panels, each with a set of circuit breakers to distribute power throughout the house. National Electrical Code (NEC) states that service entrance equipment must be rated to supply all the devices it serves.

Where are the two load centers in a house?
Both panels are in the same structure, a single family house. The original panel is in the garage; the new panel is just outside the side door to the garage – say 5ft apart. Both panels are main breaker types. The new is a Siemens PW2020B1100 w/copper bus in type 3r enclosure.
Can a double panel be used for a feed breaker?
NO, you cannot simply “jump off the top of one panel to feed the other”, unless it is designed for this purpose. Another option is a feed-through panel outside. This lets you continue the full 200A in to the house, and you can have a 100A sub-feed breaker for the barn.
