“Some outlet boxes (plastic) don’t require a stud for mounting as they have tabs that will rotate outward to retain said box against the backside of whatever wall material is being utilized. Hope this helps.”
It’s called a ‘New Work Box’ and, as you write, the tabs rotate and clamp onto the back of the drywall via a screw.
Our house is made of SIP panels (structural insulated foam) and all of the exterior electrical boxes HAD to be new work boxes...

Yep.... same here. Reworked two homes so far with 200A panels. Gramps was a Master Electrician so I must have it in my genes. Not that difficult really once you understand electrical flow. Mistake many make is carrying their understanding of automotive electrical systems over to home systems.... big no-no. Black isn’t the ground in home systems.
