I know this may be off topic but I can’t seem to find a solid answer. I’m wanting to install a nest outdooe camera above my garage and run the power cord into the attic and plug into a socket. Is this safe?
No issues. The only problem is the size of the USB plug which means you need a 3/4" or so hole to get it through. If the wiring run is long and the weatherproof transformer box will be outside, then you will need an even bigger hole in the wall to accommodate the plug.
