I have a meter, 200A breaker, and a main lug with feeder over current protection all at a utility pole. I want to run an underground feeder from there to a house load center, outdoor and with a main breaker. Can I run 3 wires from the main lug circuit breaker to the load center and then bond neutral and ground at the load center, i.e., at the house? Or do I have to run neutral and ground all the way to the main lug and bond there? The underground feeder is about 200 feet long.

Since your first disconnect is at the pole you need to run 4 wires to the building and keep neutrals and grounds separate. You also need ground rods at the building.

3-wire is only permitted if this is a mobile home setup.

3-wire main

Even though there are some AHJ's that permit 3-wire for residential, 4-wire in this case would be required to meet NEC and IRC rules. Check with the electrical inspector first. :)

An electrical inpsection is not required in rural location that I will be doing this work. No permit is required. If a 3 wire feeder is safe, I guess I'd go that way. The house is more of a cabin, only 4 120v circuits and I might run a well pump from the load center.

It’s amazing that people will count the cost of a 4th wire, but won’t count the cost of a life saved.

OK, sounds like 4 wire from utility pole with fist disconnect to house. Would this also apply to a feeder I would run from the utility pole to a barn, i.e., is there any difference between the the house and the barn.

To answer a couple posts above, I replaced the service when I bought the property. There's an old house, barely electrified, that will eventually be torn down to make way for a new house--but for now I'm using it as a cabin. The reason I put a main lug on the utility pole is to run multiple feeders--at least to house and barn.

Since there's no permitting or inspection, I have no inspector to ask as was suggested. The AHJ, as far as I know, is the utility company and they don't care/won't advise anything after the meter.

As to another post, I think I was explicit about wanting to have a safe installation, I don't understand why you blasted me for not caring about safety and only wanting to save a buck. Here's my news to you: if you can't tolerate a noob asking how to do something right, a DIY chatroom is the wrong place for you.

The house and the barn will be wired the same. Four wire feeds and each site will need a grounding electrode system - two rods or a UFER.

Ypu will need a separate OCPD (circuit breaker) at the pole for each set of feeders. The OCPD is sized based of the feeder size.

well system

Believer, Interesting that you are planning to use plc/multiplex looping for monitoring your well operation? (by CPU) Or are you? Just curious.

FYI: Depending on the type of pump setup, (Grundfos is popular with DC standalone systems), but if you are running 240Vac, a 2-wire 4" pump will be a lot less costly and easier to control with pressure auto switch at storage tank. A 2-wire w/gnd 240V feeder from the pole on a separate OCPD is all that would be necessary to the well head. (If a cap controller is used, then a control box at the well head will be needed for a 3-wire drop.
