Tap in one building to feed a service in another?

[JoeNorm]

I have a 200 amp remote meter/main on the street that feeds a small residence. Service comes into crawlspace to a large junction box where a splice is made to feed the main panel.

I want to connect into this splice and bring a new feeder outside to a new modular small building that is being delivered. Is there any code stopping me from doing this?

It seems fine to me but not sure if I am missing something.

Since you have a main at the meter the house is fed by a feeder and not a service. A connection to the junction box would be a feeder tap and have to comply with the rules in 240.21(B) unless the conductors to the modular building are the same size as the feeder that supplies the house.

I could make them the same size. My main concern was the tap originating in the crawlspace of a different structure.

IMO - it would be much easier to abide by feeder tap rules that don-resqcapt19 was speaking about (and safer) if you were to make your tap from the meter/main outside, and derive your tap outside. otherwise, depending upon the size of feeder conductor you're planning to run, you're limited to the length that tap can travel through that crawlspace before hitting an OCD. that is, unless you're running full-sized 200a feeder to this outbuilding. better do some reading up on 240.21(B).
