My husband has been installing all the electrical stuff for my studio. He had to drill a bunch of holes through the studs, and then string the heavy yellow wire all around, connecting the outlets. The metal plates are where we had several studs close together and couldn't drill a hole - instead we chiselled out a chanel. The plates are to prevent anyone from accidentally drilling/nailing into the wire once the wall is done. I'll have 10 outlets in my space! Apparently you can have too few, but never too many. We'll have 5 circuits between the studio and the workshop/garage, with 20 amps per circuit.
The next step is insulation for the walls, which my husband is being super safe with. He's wearing an air mask and being really careful with ventilation and not wearing the same clothes inside the house. Fiberglass is nasty stuff.
After that we've got just a few little details to attend to, then we're moving everything out before the drywall crew comes on Tuesday. Besides the slab, this is the only other thing we're paying someone else to do. Why? Because honestly we don't want to do it, and this way I can move in faster! : )
