The most difficult task I encounter when wiring switches or outlets is getting multiple devices within a multi-gang box to align properly so I can put the cover plate on.
What are some tips to get them lined up so all the cover plate screws will go in?
Note: I'm not talking about wiring the switches or outlets themselves, just getting the devices lined up within the box since the device mounting screw goes through a hole in the box, but a slot in the device. This makes it easy for the devices to not be perfectly vertical or for 2 devices to be too far apart or too close together to match up with the holes in the cover plate.
I know this is rather broad and there will likely not be a "best" answer. If there's support, I'll happily make this community wiki and would recommend the answers be made such, as well. Except that I don't see the "make wiki" check box that I thought I'd seen before.
