Hi,
I looked at a 200A Sq-D panel yesterday before I installed it and the panel can be installed in any vertical position. I have always been aware of the LINE/LINE markings in the panel and knew that the panel could be installed breaker up or down.
I guess I have never really had a reason to do it.
I think it is better up high. People like to lay tools, parts and other FOD in the bottom of the panel. Having the breaker low could be inviting trouble.
Regards
Greg
