I'm doing some remodeling in our basement, and came across the following (see pictures). It looks like the contractor simply wrapped tape around the conduit to secure the box to the wall.
How are exterior boxes usually secured to an exterior wall? What is the "correct" way to prevent weather and/or critters from accessing the hole in the siding? I saw a similar post that mentioned caulking the box to the exterior wall, but is that how it's usually done? Are there any IBC codes that apply in this situation?
