The meter base is on a pedestal wall approximately 30 ft from the load center. The lines then run to the disconnect on the same wall, which becomes the main panel. The conduit will run from the disconnect under a slab for the new addition to the old main load center that will now become the...

That is for the load center. I need something for the disconnect. The only way that would work would be if one of the forks would fit into the present lug (and if it would be acceptable to the inspector) and the 2/0 would have to be run in from the side.

I have a Siemens 200 amp disconnect running from the 320 amp meter base to a 200 amp panel with 4/0, 4/0, 4/0, 2/0 to a 200 amp panel. My problem is that the small lug for the bond is too small for 2/0 wire. What are my options?

For some reason it does nor appear that my first posts are being posted. When I submit I get logged off of the site. So here it goes again. The current size is 2000 sq. ft. The new addition will add another 2000 sq. ft. My current 200 amp panel is completely full. The new panel will have...

I am retyping this, because apparently my last response did not take. There will be two sweep els. I do mean 250 kcmil. Can anyone tell me how we get MCM (mcm is smaller than oughts) from kcmil? As an engineer going from kilo to mega for the same measure makes no sense to me. Back to my...

Going with three 450 that is the max for 2" conduit. Would I be better off with 2 1\2" conduit?

The ATS does have automatic load shedding, but whenever the generator has been in use it has not had to implement it.

Does that mean I need to go with #250 from the meter to the 200 amp disconnect and from the disconnect to the current 200 amp panel. Do I need to pull four #250 thus going to a 2 1/2" conduit or can I pull two #250 and two #4/0? Are there any other options?

The ATS/generator will be disconnected from the old panel and will only supply the new panel. What about the cables to pull?

Currently I have a 200-amp service through an automatic transfer switch (ATS)/20 KW generator system. I will be adding an addition to the house that will enclose the current meter and the ATS/Generator system, so they will have to be moved. I will need power to the current panel during...
