This looks to me like a hack "pro" did the work. No DIY would waste good wire like that. And the framing and concrete look professional- they use pressure treat where they need to, proper tie-down bolts, looks like the right fastener schedule was used, etc. Pity they'll have to come back and replace so much of it to pass the framing inspection. Plumbing looks pro, too.
Doesn't recessing those panelboards in the wall separating the garages pretty much kill any fire ratings that they would otherwise have?
Here in the US; interior garage walls would need a 2-hour fire rating to keep a fire in the garage from spreading to the house.
No, recessing the panelboards like that is OK under IBC/IRC. The sheet metal housing acts as a firestop. Same goes for HVAC- it's OK, so long as the penetration is metal. So, ductboard in the garage, metal take-off punched through the drywall, transition to flex just inside the wall = OK. Plastic boxes with plastic covers are surprisingly OK as well, I guess 4" holes aren't the fire risk they may appear to be.
You have to figure that not only is there 5/8" type-X gypsum wallboard, the walls are also packed full of firestopping fiberglass insulation. It's not intended to stop a fire, or stop the spread of fire, just allow enough time for the occupants to escape before the house collapses.
