Yea, commercial has far stricter inspection and material requirements then residential. You're playing with a whole lot more angry pixies in a pipe.
Most of the overlap I see is when there is a commercial building collapse (economically, not literally) and you end up seeing master electricians working on residential. Much more rare to see the opposite movement unless it's a permanent change.
