As with any switch or outlet cover that uses 14 or 12 solid copper, do your best to keep the cords inside the box as much as possible to keep. Maybe. Installing this panel is much easier when there are no wires trying to pry the panel out of the box. The plastic is transparent so you can see the devices inside and there are 2 squares on the bottom where the cables can protrude. I have used them for WiFi switches to control pool lights and the case works fine. Whether it is UV-resistant and does not fog up remains to be seen.
