Meter bank against a wall that will be removed

[electrofelon]

I am in the camp that thinks it would not be that big a deal for "can do electric". "Can't do electric" might have a tough time though. Block under it to take the weight as has been suggested, and maybe some strategically placed 2x4's or strut in a couple places. Even if the plywood has to come off I imagine that whole mess will pretty much want to stay where it is with some support and blocking. If those are sealed meters, probably will need the power company to come replace seals as you will likely need to get some new screws in there. I would plan on having the electrician there while the wall is being demoed.
