I need to get about 60A back to a bathroom/bedroom remodel. Istarted putting in a sub-panel to handle the extra breakers, but then thought about running a hi-amp wire back to a sub-panel in the bedroom instead. Running a single big wire instead of 5 or 6 smaller wires will be more efficient electrically, and seems like it would be cheaper, but I don't know about code, or how much 3 conductor plus ground costs in 4 AWG (60A, 150ft). Probably alot :-(.
Does code care if I run a 60A line from a 60A main breaker back to a sub-panel in the bedroom area, or do I have to put the sub-panel right next to the main breaker box?
