Yes. It is a sub panel.

The term service is not applicable here. This is a feeder. You will need an EGC run with the feeder conductors (in addition to the neutral) and a GES at the pump house. You do not bond the neutral at the pump house, just connect the GES to the EG bar.

Texie and Gus bring up good points.

Sounds to me like the OP is installing a meter with main disco on the pump house and the sub at the main house.
That may be the case. Either way..a panel fed by another panel becomes a subpanel and texie and jumpers post are valid.. mine would not be./

OK, same thing, just reversed. But how do you have a house fed by 40 amp?

Well, that is a good question in terms of calculated load, but as far as minimum service size rules go (either NEC or POCO), they do not apply to feeders to the house.

225.39 Rating of Disconnect. Pretty much mirrors the requirements of 230.

All the residential well houses I've been in usually had a single circuit feeding them, sometimes a small sub for the nicer ones. Why do you need a 40 space 200 amp panel for yours?
we took you all the way around the world,.,.,partly my misunderstanding...
to summarize: (a) the house panel would be a sub panel, (b) you need a EGC from the pump house to the house, (c) both locations need an grounding electrode system, (d) follow Art 225 Part II as far as location, etc on the house panel, and Art 230 for the pump house (as mentioned they are similar)

My apology to the OP for misunderstanding and misreading your post. I think I got now-the service on the pump house with a few branches and a 200 amp feeder to the house. I'd be inclined to use a 8/16 space feed thru meter main combo. Simple and inexpensive. But it is still a feeder to the house which means a GES and unbounded neutral at the house and an EGC run with the feeder.

It is not a code term, it is a field term.

It is not in the code. However it typically would mean a panel supplied by another panel which in NEC terminology would mean it is not service equipment or a branch circuit which leaves us with it being supplied by a feeder.

In code terms I think it is better described as load side equipment.
