Is necessary to put a disconnect on a house, that is going to have the ,
Breaker panel in the basement?This will be a 200amp under-ground service.
The Entrance wires will come out of the bottom of the meter base.
Straight down the outside wall & Sweep thru the Block wall into one of the,
The top Knock-out's of the Breaker panel.

Couple things might trigger that requirement...
if the panel indoors is sufficiently far inside that you'd otherwise have too much unfused service conductor inside, then you'd need some sort of OCPD outdoors.
if you have local rules requiring an outdoor disconnect, no matter what, for easy access by the fire department.

For the proposed arrangement you describe, my answer would be "no, not unless you want to".
 
Marc You have made a good point.
Here in our area we have to install a disconnect if we have more than ,
2Ft. of Conduit concealed in a wall.The conduit must Rigid (metal)
with a grounding Bushing. Panels installed in basements behind and ,
just below the meter base we in the past have not used a disconnect.
It is Not a problem to install the Disconnect. And it is probably a good Idea.
I was just curious about the requirements in other areas.

In This example, per the NEC an outside dsconnect would not be required.

Just for discussion purposes.........

Just for discussion purposes.........

Built my own home and large "shop" myself in 1998. Because I built the barn first, I brought in a 320 A service to barn. Then ran 200A service to house. Here is the rub.....According to local inspector, because "technically" the first disconnect (barn panel) was located inside the barn, he made me put the 200A DC for house and the 40A DC for the A/C INSIDE the barn. His reason was that all disconnects MUST be located together. My point was that the fire people would have to "break" in a very heavily reinforced barn door to shut off the power instead of pulling pole fuse, pulling the two meters or accessing outside disconnects which is what I wanted to do. He wouldn't buy it and I had to put DC's inside the barn.

For what it's worth.....

In WA State, the limit is 15 feet.

Isn't it just a "disconnecting means" that is required (i.e., no overcurrent protection is required)?

Shouldn't the house have a main disco also?
 
House does have a DC

House does have a DC

"200A DC for house and the 40A DC"

House does have a DC as does the A/C. My point was that I wanted all DC's outside at the meter mounts for easier access for fire dept. Inspector required that they be inside the barn.
