Yes, you want your load to come through the 200 amp main breaker if you have
a 200 amp meter can and service. Connecting up stream or bypassing the 200
amp main could allow you to overload the service.

I'm not certain what the codes say, but a disconnect on the outside of your
main service panel could be a good idea just before you go underground. When
you come up to the new service, a fused disconnect shouldn't be necessary if
you come through the wall, and immediately in to your new panel. If you
cannot locate your new main panel, just inside the wall from your service
entrance, then yes, a fused disconnect would be a must.

What size panel for the new garage would I need? (If my home service
is 200 amps, and my current sub panel is 100 amps?) Can I put another
100 amp panel in my new garage/shop?

I will have to route the cable under the house (crawl space) and
outside under a deck to a ditch to the new shop. So you are sayign a
disconnect where the wite comes out of the house? (Which would be
under the deck).

B the way, I will have to disconnect somethignin the main panel to
give me space for the extra sub panel. If there is not enough slack to
move it over. (wire wise). What can I do?
