Well, that's where part of the expense lies. Not only do you now have to span the entire room because there's no load bearing, but we can't deny them access to power and communications. So the movable walls I've been dealing with have to have electricity and date ran into each panel separately, then flex connected to an approved juction box that can be connected or abandoned depending on where the wall may be relocated. Which is a new one for electricians and inspectors.
This makes it even MORE fun for contractors, because I show wiring these devices on my electrical drawings, but the electrician ASSUMES the movable wall mfg will prewire the panels. The GC ASSUMES the EC has wiring covered (since it's on his drawings) and orders the panels without prewiring, and they get installed. I do my above ceiling punch, and notice there's NO wiring going to these panels...and no outlets ON the panels. So now the GC is forced to tear off the face of these factory panels and pay the EC to run wiring, and cut openings in these panels for boxes.
It's just complete chaos all around
