I posted this over at electriciantalk, and only found 1 or 2 guys responding with experience in this topic, so here goes....... I've heard good things about this forum.
Recently I've run across several Siemens/ITE residential main breaker panels with burned spots on the aluminum buss or burned lugs on the main breaker.
The line lugs are separate from the main breaker and those lugs have lugs stabs, into which the main breaker plugs in. The main breaker is similar to four single pole breakers ganged together. Since we're replacing it, the old arrangement wont' matter.
I think these G4040 200a panels are 39" in height. The Siemens G4030 is shorter and the G1224 is much shorter. All have the same lousy main breaker setup and the same lousy al buss. It looks as if the Sq D Homeline HOM 40M, or 40L, or 40V have the right height, depth and width dimensions to cover 39".
Obviously the swapped panel cover, has to cover the 39" height. Most every residential panel is going to be 14 1/4 wide and 4" deep. Is there anything else to look out for? A new panel cover which matches the new guts will obviously line up perfectly, breaker-wise, as long as you have sufficient wireway clearance at the top and bottom of the can. We'd plan to screw the new guts to the back of the old can, screwing through the plastic backing - just as Seimens does it.
I've seen the $400 CH retrofit kit but at that cost, it's a killer. They are not currently UL listed anyway, according to our CH rep.
Yes, I know we can remove the entire old panel and can, but would prefer not to, if that can be avoided.
