I am upgrading to 200A service. I am trying to figure out placement for my main panel. I would like the wires to run through the back of the meter, through the wall and straight in to the back of my main panel. The only back knock outs on my main panel box are at the bottom.

Can the wire come from the meter in to the back bottom of the main panel, then up to the top for the main breaker connection? not finding where this might be addressed in the code.

this location is good, because it puts the meter and the main breaker at eye level, just on opposite sides of the wall.

If not, I guess I will need to run conduit in the wall from the back of the meter to the top of the box and down.

Thanks,
Michael
