That was my first thought as well. I think I already asked him about it. When installing concrete siding they expect you to put a solid wood base and the siding should be cut around it. Just installing directly on the siding is not ideal and I hope they at least used some kind of standoff or spacers that the box pushes against so it's not pushing against the siding.Hard to tell in that pic, but it looks like they just screwed it directly to your hardi-plank siding, which will compress it. The pic also shows a rough hole in the siding begging for water intrusion. Water problems may be in your future and for the quotes these installers are throwing around ($500-$1,000/hr.) they should be called back to correctly waterproof their install (if they even know how to properly do it). Sorry, but I'm not happy with how Tesla is not allowing us to choose our own installers who we know do things right and instead forces us into using non-competitive contractors.
Thanks for the help. I'm surprised you saw that I deleted it right away. I had the wrong world scale in coreldraw. It works for my needs but it's lame that the different pages or tabs in the same file all use the same world scale so I have to keep switching back and forth.16-1/4” X 25-3/4” glass, the box is a bit under 16” x 25-1/2”.
Does look like a huge load center if to scale. But it is not, as the box for the gateway is depicted at about 16” tall based on the 23” dimension lines.
