The picture is service to bldg 1 coming from underground into a gutter ,from the gutter up to a disconnect that feeds bldg #1. Out of the same gutter service goes underground to bldg #2 and ends at a disconnect that feeds bldg #2.
Are these sec to both bldgs? And the disconnects are both rated for total service or taps from the gutter. As in a 200 amp service and each bldg has 100 amp disconnects?
Are the disconnects both bonded neutral to ground, if bldg 2 isnt a sub panel?
And last what the advantage of this method vs sub feeding bldg 2 ?The added ground is one.
 
I believe this is the pic

Thanks Mr.Dennis.
The neutrals and grounds bonded at both.
Tap rules could apply if bldg 2 was gonna be 100 amps.
When grouping how does having a service disconnect at seperate buildings work or does grouping apply to ,,at each structure?
 
(no where near "mr dennis' capacity but....)
Think of it as two houses and POCO puts a pull box in the ground and you run a service conduit to each house from the pull box.
Now simply move that pull box up the wall and make it a wireway......
Two sets of service conductors from one common point. No equipment grounds.and no tap rules as we are dealing with service conductors.
The conductors to #2 don't enter Bldg #1 in any manner.
 
Thank you as well Mr.augie.
Does the picture apply to residential or commercial or both.
I tried to look in my code book but 230.14 isn't a article?
 
applies to all services.
Note however some POCOs have rules that may govern such installs also.
(In one area I work, that install is prohibited by the local POCO)

This is spot on. These are two seperate services and should be treated as such. Try not to get feeder rules mixed in here.
 
Thanks.
I have a friend who bought a house and the panel is in the bathroom next to the toilet. The house was built before 1993.
Poco has overhead service conductors going to a pole next to a 6 car garage. From that pole the service goes the service point at the house.
He wants to move the panel and convert the garage into a game room ...not the gambling kind.
The garage has only one circuit from the house. Structures are not connected.
I'm thinking something like the picture or a main breaker panel in the garage and sub feed the house. Trench 10' from bldg to house.

If I was going to do what you propose I would remedy the panel in the bath room situation. Either remove the stool & sink so its not a bathroom or move the panel. You could leave the panel enclosure in place & use it as a junction box. Or could you make an electrical closet at the panel & meet clearance requirements ?
 
The attic access is in the hall opposite the panel,I suggested putting a j box in the attic so he can trace out the loads and decide if they are gonna work for him.
Remove the panel which led too how to re feed it and to feed the new game room/garage.
