Service Drop

[skylink]

Hello, I'm working on an industrial building and the owner wants the service drop and main breaker panel installed several feet away from the building.
I live in Washington and I know code says a service disconnect installed outdoors must be "..within sight and within fifteen feet of the building or structure served."
Does anyone know any codes regarding installing a Main Breaker Panel several feet from a building that will accommodate a large number of circuits?

You must have some amendment in Washington because there isn't any code that says it must be within 15' of the structure,

Also if the panel is on the pole you want to run all the circuits for the building to the pole? That will not be compliant IMO

I think 225.30 (E) would allow it.

I think 225.30 (E) would allow it.

225.30 (E) states, "Different Characteristics. Additional feeders or branch circuits shall be permitted for different voltages, frequencies, or phases, or for different uses such as control of outside lighting from multiple locations."

I'm not sure how that applies?

Yeah, it's an additional rule in my area. The drop and panel would be secured to a nearby structure. Not on a utility pole.

My point was that you can't have more than one branch cir. or feeder going to the service from a different structure.

Maybe it is (F) that allows for multiple feeders in Branch circuits if under control of single management. I was looking in 2017

Thanks for the reply!

Is that from Article 225.30 "A building or other structure that is served by a branch circuit or feeder on the load side of a service disconnecting means shall be supplied by only one feeder or branch circuit unless permitted....?”

But where does it say in the NEC that a main breaker panel can't be detached from a building that it's serving.

Also, I don't think this article would apply, that's assuming it's what you were referencing.

I thought you said that you were bringing all the circuits out to the service disconnect?

 

[retirede]

I agree with Dennis. Not having the main panel attached to the building is a violation because it results in more than one branch circuit run to the building.

I’m not sure it was the intent of that section to disallow what you want to do, but it does.

They want a NMEA 3R 42 Breaker Panel with the main disconnect as the service disconnect installed several feet from the building.

And that is what I have been responding to.. Definition of structure--- That post in the ground is a structure as it is not a piece of equipment

Structure.

That which is built or constructed, other than equipment

Since that is a structure then everything going to the post is either a branch circuit or a feeder and that is where 225.30

225.30 Number of Supplies.

A building or other structure that is served by a branch circuit or feeder on the load side of a service disconnecting means shall be supplied by only one feeder or branch circuit unless permitted in 225.30(A) through (F). For the purpose of this section, a multiwire branch circuit shall be considered a single circuit.
Where a branch circuit or feeder originates in these additional buildings or other structures, only one feeder or branch circuit shall be permitted to supply power back to the original building or structure, unless permitted in 225.30(A) through (F).
