| Nov 20, 2021 at 17:01 | comment | added | Ecnerwal | There are usually some screws holding those in place as well as the slots, often not visible with the breakers in. I have the QO not Homeline, and I know those are reversible top to bottom, but I had to make a point of telling my electrician to put the main on the bottom as he was defaulting to main on top. I prefer not to work around the main feeds running all along the sides and getting in the way. Only actual effect is that I have to hold my generator interlock up to flip the main on - not a big deal, as rarely as I use that. | |

The marking of "LINE" being marked twice so right side up no matter which way mounted indicates it can be mounted either way. I mounted this same panel the other direction in a house I owned in 2001. Finding the exact instructions for that panel might be difficult due to plug-on-neutral updates to currently available product line. The ground bus is connected to code. | |

The plastic that holds the neutral and line buses and the main breaker is held in place by gravity with tabs in slots. The only way to get the main breaker on the bottom would be to rotate the entire panel, and then those tabs would be falling out of the slots. And my service comes up from the ground not down from a pole outside. I think they did the best they could :( I might be missing something though, especially given my ignorance in having to ask this question :) | |

Code is minimum. It's OK to exceed it | |
