Thanks for the replys. these really helped. Would the derating be such an issue due to the fact that all the wires were in the old panel anyway or is it because i am now feeding back out. I have 9 12/2's 4 14/2's one range, one dryer, and one hot water heater. i was going to use a seperate j box for the range anyway.
thnanks again for the input
