I want to run the line power from the utility pole thru an underground service to a main panel on my shop, then to a 125 amp subpanel in the shop and thru 70 ft of buried 2.5 in pvc conduit to a 200 amp subpanel in my house. (the shop is bettween the utility pole and house) I have a siemens MC0816B1200SCTM 250 AMP MAIN PANEL. it has a 200 amp main breaker , it has 8 stabs, the largest breaker it can take is 135 amps, which is fine for the shop, but i still need 200 for the house. the buss bars have what look like large feed thru lugs at the bottom that i could use for my 200 amp subpanel in the house. the label in the panel says those lugs take from #4 thru 250 kcml wire, which would work for a 200 amp subpanel, but there is nothing on the panel saying it's rated for a 200 amp feed thru. Is that something i can do with this panel ? If so, at what depth would the conduit going to the house need to be at ?
thanks, mike
