need advice for outdoor mounting of boxes
I need to mount the outdoor box (pictured below) onto my vinyl siding (pictured below) for an electrical line.
I also need to mount the PVC pull elbow (pictured below sticking out of the mulch) for my sprinkler system wiring into my cinderblock wall which will connect in my basement.
I need to know from start to finish what I need to do for each of the two tasks. I can't find this information anywhere.
For the electrical box I will be drilling through my sill plate and right through the siding. Do I need to enlarge the hole from the outside? After running the wire through the hole in the wall and mounting the box, what do I use to seal the hole in the vinyl siding outside and how do I go about doing this?
For the PVC elbow, I need to rent a hammer drill to make a hole large enough (from the basement outwards) for the PVC to fit in. What should I use to weatherseal it from the outside and inside? I plan on putting an identical elbow inside the basement on the other side of the hole.
For the electrical box, I'm going to have a tough time finding a spot for the junction box in my basement near my sill plate. It doesn't have to be mounted right over the hole right? If not, what should I use to fill the hole in the sill plate after running the UF wire through to a suitable location for the indoor junction box?
